How to Format Email for Maximum Readability: Paragraphs, Bullets, and Proven Strategies
Most professionals receive 120+ emails daily and spend just 11 seconds per message. Poor email formatting—dense paragraphs, buried action items, weak visual structure—causes recipients to ignore or misunderstand your messages. Proper formatting using strategic paragraphs, lists, and accessibility standards transforms emails into effective communication tools that get read and acted upon.
The average professional receives over 120 emails daily, and most recipients spend less than 11 seconds deciding whether to read, skim, or delete each message. If your carefully crafted emails consistently get ignored or misunderstood, the problem likely isn't your content—it's your formatting. Dense paragraphs, buried action items, and poor visual structure create cognitive overload that causes recipients to abandon messages before grasping their purpose.
Email formatting directly impacts whether your message gets read, understood, and acted upon. Research from
Nielsen Norman Group
demonstrates that users don't read digital content word-for-word—they scan for key information using headings, lists, and visual cues. When emails lack proper structure, recipients miss critical details, ignore requests, or simply move on to the next message. This isn't just a minor inconvenience; it's a communication failure that wastes time, creates confusion, and damages professional relationships.
The challenge intensifies because email serves multiple roles simultaneously: it's a communication channel, an archival system, a task management tool, and increasingly, a legal record. Poor formatting doesn't just reduce readability—it creates compliance risks, excludes people with disabilities, and undermines your professional credibility. Understanding how to structure paragraphs, deploy lists strategically, and apply accessibility standards transforms email from a source of frustration into an effective communication tool.
Email remains the dominant communication channel in business, academia, and government despite the proliferation of chat platforms and collaboration tools. Professionals often receive hundreds of messages daily, forcing them to triage quickly. Messages that appear visually dense or difficult to scan get skimmed, misunderstood, or ignored entirely. Microsoft's Outlook best practices explicitly advise keeping messages short and to the point, organizing content from most important to least, and using formatting such as bold text and separate lines to make action items stand out. The consequences of poor formatting extend beyond immediate comprehension. Email creates a permanent, searchable record that can be forwarded widely and may serve as documentation in disputes or audits. When messages are poorly structured, key obligations, deadlines, or disclaimers get buried in dense text, increasing the likelihood of non-compliance or misunderstandings. The American Psychological Association emphasizes that email's permanence means unclear or ambiguous messages can have long-term consequences for professional relationships and legal exposure. Accessibility regulation has transformed email formatting from a courtesy into a compliance requirement. The Web Content Accessibility Guidelines (WCAG) 2.2 articulate detailed criteria for text presentation—including line height, paragraph spacing, word spacing, letter spacing, text width, and reflow behavior—that directly apply to HTML email content. Organizations increasingly treat email as part of their public-facing digital infrastructure, and messages that ignore accessibility practices risk excluding users with disabilities while potentially violating Section 508 in the United States and similar regulations internationally. The Litmus accessibility guide frames these standards as intertwined with legal requirements, noting that WCAG conformance is widely recognized as the benchmark for accessible digital experiences. For email clients like Mailbird that position themselves as productivity tools, supporting readable formatting isn't just good practice—it's essential for serving diverse user populations and meeting organizational obligations. Readability has a direct economic dimension tied to productivity and engagement. Nielsen Norman Group's long-term research on marketing emails and newsletters finds that usable emails—those with clear structure, concise content, and scannable layout—significantly improve engagement, task success, and user satisfaction compared to poorly designed messages. Business publications highlight that better email writing can reduce miscommunication, shorten decision cycles, and improve collaboration, especially when senders front-load their main point and use formatting to clarify calls to action. For content creators using email clients with productivity features, mastering paragraphs and lists becomes part of the broader strategy of efficient digital communication. When emails are formatted for quick comprehension, recipients can process them faster, respond more accurately, and move forward with less friction—benefits that compound across hundreds of daily messages. Understanding email readability requires recognizing a fundamental truth: people don't read emails the way they read books. They scan for key information, often reading only the first sentence of each paragraph and relying heavily on headings, highlighted text, and lists to locate what matters. Nielsen Norman Group's research on web usability demonstrates that in controlled studies, sample sites scored 58% higher in usability when written concisely, 47% higher when made scannable, and 27% higher when using an objective tone rather than promotional language. This scanning behavior maps directly onto email, where long messages require extensive scrolling and recipients must quickly determine whether an email is actionable or can be archived. Users dislike long, scrolling pages and strongly prefer text that is "short and to the point." When the same information is presented in paragraph form versus bullet points, recipients are more likely to skim and miss critical data in paragraphs, whereas bullet points encourage careful reading and retention. Cognitive load theory explains why paragraph and list formatting exert such strong influence on email readability. Human working memory has limited capacity, so when information is presented in dense, unstructured form, readers must expend more mental effort to segment and organize it internally. This increases the risk of overload and misinterpretation. Providing clear external structure—through short paragraphs, headings, and lists—reduces the intrinsic cognitive load associated with parsing content. Business writing experts explicitly advise opening up text with white space and separating paragraphs, noting that this makes it easier for readers to differentiate points, sub-points, and ideas. When each paragraph encapsulates a single concept and begins with a clear statement of that concept, readers can quickly form a mental model of the content and decide whether to engage more deeply. Lists provide another form of chunking that manages cognitive load effectively when presenting multiple items or steps. Email writing experts note that lists of three or more items should be broken out into bulleted or numbered form, with a brief introductory explanation of what the list contains. The formatting creates white space and prompts readers to pause after each item, reducing the likelihood that critical information gets overlooked during rapid scanning. Readability isn't solely a cognitive phenomenon—emotional and social factors affect how email content is interpreted and whether recipients feel respected and motivated to respond. Poor formatting can signal carelessness, disrespect for the recipient's time, or lack of professionalism, which may diminish goodwill and cooperation even if the content is technically understandable. Purdue OWL advises writers to use standard spelling, punctuation, and capitalization, warning against ALL CAPS and text abbreviations that might appear unprofessional. Emotional responses are also shaped by how requests and information are presented within the email structure. Hiding the real question or request at the end of a long email is a common frustration, as recipients must wade through context before discovering what is actually being asked. When requests are buried in dense text, recipients may feel ambushed or overwhelmed, leading to delays or avoidance, whereas clear, segmental formatting reduces anxiety and supports timely, cooperative responses. Guidance from business writing, usability research, and professional etiquette converges on a clear recommendation: email paragraphs should be short, focused, and limited to one main idea. Business writing training materials advise dividing emails into paragraphs averaging around five to seven lines, cautioning against writing messages as a single large block of text. When a paragraph reaches about seven lines, writers should look for a natural break corresponding to a new idea, though this serves as a guideline rather than an absolute rule. Small paragraphs of two to five lines should be used freely, helping to keep each unit of text manageable and visually distinct. Purdue OWL echoes this sentiment by urging writers to use clear, short paragraphs and be direct and to the point, explicitly warning against unnecessarily long emails that waste recipients' time. The APA's etiquette guide adds that short paragraphs with skipped lines between them help ensure that questions are not missed, because readers can quickly locate and isolate each segment. Nielsen Norman Group provides experimental support for the one-idea-per-paragraph principle. In their studies, participants scanning long paragraphs often reported difficulty locating information and expressed a desire for paragraphs to be broken into pieces, one for each topic. Researchers also observed that many users read only the first sentence of each paragraph, which highlights the importance of topic sentences as a way of conveying the core idea upfront. When each paragraph covers a distinct topic and begins with a clear, informative sentence, scanners can decide whether to read further or move on, enabling efficient triage. This structure is particularly important in email, where recipients may be reading on small screens with limited visible lines per page, making paragraph boundaries and first sentences crucial cues. Topic sentences are critical for email readability because they serve as the main anchors for scanners. Nielsen Norman Group's observations that users rely on the first sentence as a summary underscore the need for content creators to craft topic sentences that clearly state the paragraph's main idea rather than burying it in the middle or end. By combining strong topic sentences with the one-idea-per-paragraph rule, authors create a predictable structure that helps readers rapidly build a mental map of the message. Outlook's documentation recommends organizing content from most important to least, ensuring that high-priority information and action items appear early in the message rather than being hidden at the end. This translates into front-loading essential instructions or decisions, then elaborating with context in later paragraphs, making sure that each paragraph supports the overall information hierarchy. Plain language is a foundational element of readable paragraphs, especially in mixed audiences. GOV.UK content guidelines require content to be written in clear, plain English, free from unnecessary jargon, and optimized for web readability. The Litmus accessibility article recommends keeping sentences around twenty words or less, using active voice, and avoiding slang or jargon that may confuse some readers. Directness and objectivity in tone enhance clarity within paragraphs. Nielsen Norman Group's experiments found that objective writing—free from promotional exaggeration—improved usability because users could more quickly discern factual information and tasks. Within paragraphs, this translates into stating facts and requests clearly, without hedging or rhetorical ornamentation, and separating distinct issues into different paragraphs rather than conflating them. Bulleted and numbered lists are among the most powerful tools for enhancing email readability because they exploit scanning behavior, allowing readers to quickly parse multiple items or steps. Nielsen Norman Group's research identifies bulleted lists, highlighted text, and headings as key elements that enhance scanning and usability. In experimental comparisons of writing styles, the inclusion of scannable formatting—such as lists and headings—produced a 47% improvement in measured usability. Business writing guidance explicitly endorses separating lists of three or more items into bulleted or numbered form. Instead of embedding items in a dense sentence or paragraph, authors should begin with an explanation of what the list contains, including a key term such as "steps" or "recommendations," and then present each item as an example of that term. This pattern creates white space and clarifies the semantic relationship among items. The choice between bullet points and numbered lists should reflect the nature of the content and desired recipient action. Productivity experts recommend bullet points for information that does not require a response—such as status updates, features, or options—because bullets signal that items are related but not sequential. Numbered lists work best when recipients must respond to multiple requests or follow procedural steps, as the numbering allows them to reference and answer each item in order, reducing the chance that any request is missed. Outlook's best practices recommend putting action items or questions on separate lines so that they stand out and get noticed, which is effectively a call for list-like formatting. When multiple requests are embedded in a single paragraph, recipients often respond to only the first or most salient one, leaving others unaddressed. Numbered lists prevent this by making each request visually distinct and trackable. Lists also support accessibility and inclusive design when implemented with proper HTML semantics. The Litmus accessibility guide recommends using semantic elements, including list markup in HTML, to help assistive technologies such as screen readers accurately convey content structure. When lists are implemented with proper HTML semantics—using unordered and ordered list elements rather than improvised formatting—screen readers can announce the presence and length of lists, allowing users to navigate them more efficiently. Microsoft's Outlook accessibility documentation advises organizing information into small chunks, including bulleted or numbered lists, to make it easier for screen readers and all users to read and understand email content. This semantic structure also helps maintain readability when users adjust text spacing or zoom levels, because list items remain logically grouped and visually distinct. Despite their benefits, lists can be misused in ways that undermine readability. Overloading emails with numerous or excessively long lists can create a fragmented, overwhelming layout where readers struggle to discern the overarching structure or prioritize among items. Lists should begin or end with an explanation, including the number of items and a key term they exemplify, but if this pattern is not followed, recipients may not understand the purpose or scope of the list. Lists can also create accessibility challenges when used without proper semantics or when combined with problematic visual formatting. The Litmus guide advises against justified copy and warns that poor color choices and insufficient contrast can make list text hard to read, especially for users with visual impairments. When senders attempt to simulate lists using tables or manual spacing rather than semantic list elements, assistive technologies may misrepresent the structure, complicating navigation. The Web Content Accessibility Guidelines (WCAG) 2.2, developed by the World Wide Web Consortium (W3C), provide a foundational framework for making digital content—including HTML email—accessible to people with disabilities. WCAG is organized around four core principles known by the acronym POUR: perceivable, operable, understandable, and robust. Perceivable content ensures that information can be accessed through one or more senses, operable content requires that users can navigate using different input methods, understandable content must be clear and predictable, and robust content must work well with current and future assistive technologies. WCAG defines three levels of conformance: Level A (minimum), Level AA (widely targeted), and Level AAA (highest), with Level AA being the most common target for organizations seeking to meet legal and policy requirements. While WCAG itself is not a law, it is widely referenced by national and sectoral accessibility regulations, including U.S. Section 508 standards for federal agencies and various EU directives, making WCAG conformance a de facto requirement in many contexts. WCAG's success criteria directly address text readability and layout. One criterion specifies that content must remain functional and readable when users adjust text style properties, including line height to at least 1.5 times the font size, spacing following paragraphs to at least two times the font size, letter spacing to at least 0.12 times the font size, and word spacing to at least 0.16 times the font size. Another criterion limits text width to no more than 80 characters or glyphs, recognizing that overly long lines hamper readability and tracking. Font choices are central to legibility. Microsoft's Outlook accessibility documentation advises using familiar sans-serif fonts such as Arial or Calibri, which are easier to read on screen, and avoiding excessive italics, underlines, or decorative typefaces that may reduce clarity. The Litmus guide similarly recommends using larger font sizes and ensuring adequate line height—around 1.5 times the font size—to make paragraphs easier to read, particularly on mobile devices where text may appear small. Color contrast is another critical WCAG requirement that affects email readability. WCAG defines contrast ratios between foreground and background colors using a specific formula, with acceptable contrast ratios ranging from 1:1 to 21:1 depending on text size and level of conformance. The Litmus guide recommends using high color contrast between text and background and warns against harmful content such as flickering or low-contrast text that can trigger issues for users with photosensitive epilepsy or low vision. Microsoft's Outlook guidance suggests using the "Automatic" font color setting to ensure that text displays well in high-contrast mode and encourages use of accessibility checkers to detect insufficient contrast. These practices intersect directly with email formatting choices such as colored backgrounds, colored text, and overlays, which business writing resources often advise against for purely usability reasons. When combined, WCAG and usability guidance send a clear message: readable emails must be visually clear and accessible, not merely aesthetically pleasing. Spacing within and between paragraphs is critical for accessibility. The Litmus guide advises creating enough white space above and below paragraphs and using padding within table cells or paragraph tags to move text away from the edges of emails, reducing visual crowding. WCAG mandates that when users adjust line height and spacing following paragraphs, there must be no loss of content or functionality, which means email layouts must avoid overlap or truncation when spacing is increased. Business writing guidance complements these standards by advising users to separate paragraphs with white space and keep lines of text under 70 characters, which aligns closely with WCAG's 80-character limit and general typographic best practices. These concrete formatting requirements apply to both paragraphs and lists, ensuring that all text elements are large enough, spaced adequately, and contrasted sufficiently with backgrounds. The choice between HTML and plain-text email formats significantly influences what formatting options are available for paragraphs, lists, and other structural elements. HTML emails support rich formatting, including headings, lists, bold and italic text, colors, images, and tables, enabling authors to implement many readability and accessibility practices. Plain-text emails, by contrast, are limited to basic characters and line breaks, relying on conventions such as indentation and separators to suggest structure. Mozilla Thunderbird's documentation explains that the presence of a formatting bar in the compose window indicates HTML composition, whereas its absence indicates plain text. Users can enable HTML composition under Account Settings and Composition & Addressing by selecting "Compose messages in HTML format." Thunderbird further recommends configuring sending format to "Both HTML and Plain Text," ensuring that recipients who cannot or prefer not to view HTML receive a plain-text version. Cross-client rendering issues pose significant challenges for maintaining readable formatting across diverse environments. Email clients differ in their support for CSS properties, HTML elements, and media queries, making it difficult to guarantee consistent presentation of paragraphs, lists, and headings. The Litmus accessibility guide underscores the importance of testing emails in multiple clients and using responsive design techniques, such as media queries, to adjust font sizes and line heights for smaller devices. WCAG's reflow criterion adds further constraints on responsive design. Content must be presentable without horizontal scrolling at a width equivalent to 320 CSS pixels and a height equivalent to 256 CSS pixels, which means that multi-column layouts and fixed-width tables must be carefully designed or avoided. Outlook's accessibility documentation advises avoiding fixed-width tables and ensuring that tables render properly on phones and tablets, reflecting the reality that horizontal scrolling is particularly problematic on small screens. Tables, images, and media can enhance or impair readability depending on how they are used and integrated with textual content. Tables are often used to present structured data, but they can pose accessibility challenges and rendering issues. Microsoft's Outlook accessibility documentation advises avoiding tables in emails if possible and presenting data in paragraphs with headings instead, because tables may not render properly on all devices and can be difficult for screen readers to interpret. Images and media must be carefully formatted to support readability rather than distract from it. The Litmus guide emphasizes the need to balance text and images and to avoid harmful content such as flashing animations. They recommend using descriptive alt text for all images, including GIFs, so that users relying on screen readers can understand the content. Microsoft's Outlook guidance similarly stresses alt text and cautions against using text in images as the sole method of conveying important information, urging authors to repeat the text in the email body. Mailbird is a desktop email client for Windows and Mac that unifies multiple email accounts—including Gmail, Outlook, Yahoo Mail, and other IMAP services—into a single workspace, positioning itself as a productivity tool for managing high-volume communication. Its core features include a unified inbox that aggregates messages from different accounts, integration with over 30 tools such as Slack, Dropbox, Google Calendar, and Asana, and the ability to add custom apps or websites to the interface, reducing "tab overload" by centralizing work within the Mailbird environment. Mailbird emphasizes focus and flow, offering tools to block unwanted senders and unsubscribe from annoying emails with a single click, thereby helping users keep their inboxes clean and reduce distractions. These features indirectly support readability by minimizing noise and allowing users to concentrate on the content of important emails rather than wading through clutter. The client's support for HTML formatting in compose windows enables users to implement headings, lists, and styled text, aligning with accessibility and usability guidelines when used appropriately. Mailbird's email templates are particularly relevant to readability because they allow content creators to standardize and reuse well-formatted message structures. The documentation explains that templates can be used in both Quick Reply and Compose windows, accessed via an Email Templates icon in the interface. To create a template, users compose an email draft, click the templates icon, select "Save draft as template," and then "Save as new template," providing a name and subject for the template. When templates embody readability best practices—short, focused paragraphs, clear headings, appropriately used lists, descriptive subject lines—they can significantly improve consistency and reduce cognitive burden for both senders and recipients. For example, a status-update template might begin with a brief overview paragraph, followed by a numbered list of completed tasks, ongoing issues, and upcoming milestones, each labeled clearly and separated by white space. By reusing such a template, content creators ensure that recipients always know where to look for particular information and can scan quickly for the items most relevant to them. Mailbird's AI-powered email writing aims to help users draft clear, professional messages in seconds when they are "stuck staring at a blank screen." AI tools can be particularly useful for generating concise wording, reorganizing content to place main points early, and suggesting bullet points or numbered lists for multi-item content. However, AI-generated messages may not automatically conform to accessibility or organization standards unless explicitly guided. Content creators must review and edit AI drafts to ensure that paragraphs are appropriately segmented, lists are used judiciously, and language is tailored to the specific audience, maintaining control over readability. Authors can prompt AI to produce concise paragraphs, summarize complex information, or rephrase content in plain language, and then review outputs to ensure that topic sentences, list usage, and spacing align with guidelines. Mailbird's integrations and unified inbox capabilities support efficient reading and response to well-formatted emails. By connecting Mailbird to calendars, task managers, and collaboration tools, content creators can process list-based action items without leaving the client, reducing friction and ensuring follow-through. Blocking unwanted senders and unsubscribing from irrelevant emails helps keep the inbox focused on messages that benefit most from careful formatting, improving the signal-to-noise ratio. User feedback from SoftwareAdvice reviews rates Mailbird at 4.4 overall, with sub-scores around 4.5 for ease of use, 4.1 for customer support, 4.3 for value for money, and 4.3 for functionality, suggesting that users generally find the client intuitive and effective. Many reviewers praise the interface design, calendar integration, and unified inbox, noting that Mailbird simplifies management of multiple accounts and reduces the complexity of juggling different clients. Synthesizing the evidence from usability research, accessibility standards, and email client documentation yields a coherent set of practical recommendations for formatting readable emails in Mailbird. At the core is the principle that emails should be divided into short, focused paragraphs, each addressing one main idea and beginning with a clear topic sentence that summarizes that idea. Paragraphs should average around two to five lines for most messages, with seven lines serving as an upper heuristic for considering a break when a topic changes. Topic sentences should front-load critical information, aligning with the practice of placing the main point early. Each paragraph should be separated by white space to make boundaries visually distinct, and font choices should favor familiar sans-serif typefaces such as Arial or Calibri, with font sizes large enough to be comfortably legible. Line heights should be set to approximately 1.5 times the font size, and paragraph spacing should be at least twice the font size to provide clear separation. Text should be written in plain language, with sentences kept to around twenty words or fewer where possible, active voice used to simplify structure, and slang, jargon, or regional terms avoided unless appropriate for the specific audience. Critical information—such as requests, deadlines, and decisions—should be positioned early in the email and given their own paragraphs or list items. Lists should be used judiciously to present multiple items or steps, especially when making requests or describing tasks. Bullet points are most appropriate for conveying informational items that do not require specific responses, while numbered lists are preferable for multiple requests or procedural steps. Each list should be introduced with a brief explanation that defines the key term and number of items, and list items should be concise and clearly related to that term. Lists should be visually separated from surrounding paragraphs with adequate white space and implemented using semantic HTML elements where possible, ensuring accessibility for screen-reader users and compliance with WCAG spacing requirements. When lists are combined with headings that clearly explain what an email section is about, screen-reader users can navigate quickly, jumping between headings and lists as needed. In Mailbird, these paragraph and list structures can be encoded in templates, providing reusable formats for recurring communications. Content creators should design templates with meaningful subject lines, introductory paragraphs that summarize purpose and context, list-based sections for tasks or decisions, and closing paragraphs that reiterate next steps and contact information. Templates can be leveraged with AI-generated content that fills in specifics while preserving structure, though human review remains essential to ensure clarity, appropriateness, and accessibility. Templates should be designed with accessible defaults—high contrast, appropriate spacing, semantic lists—and AI-generated content should be edited to ensure compliance with spacing, contrast, and language guidelines. By standardizing these formats, content creators reduce the cognitive load on both senders and recipients: senders no longer need to reinvent structure each time, and recipients learn to recognize patterns and know where to find key information. Content creators should adopt conservative HTML formatting that respects cross-client constraints, testing emails in multiple clients when possible. While Mailbird does not provide built-in accessibility checkers in the available documentation, content creators can manually review and adjust formatting in the compose window, using external validation tools if necessary. Aligning email formatting with WCAG and Outlook's accessibility recommendations ensures that messages are not only readable but also inclusive and legally robust, particularly in regulated industries. By viewing Mailbird not just as an inbox but as an environment for applying evidence-based formatting practices, content creators can craft emails that stand out in crowded inboxes for their clarity, readability, and effectiveness. The combination of templates, AI-assisted drafting, unified inbox management, and productivity integrations creates a powerful workflow for high-quality email communication that respects recipients' time and cognitive load. Based on business writing research and usability studies, email paragraphs should average around two to five lines, with seven lines serving as an upper guideline for considering a break when topics change. The one-idea-per-paragraph principle is more important than exact line counts—each paragraph should address a single concept and begin with a clear topic sentence. Short paragraphs with white space between them help recipients scan quickly and locate relevant information without feeling overwhelmed by dense text blocks. Research from productivity experts and business writing guidance indicates that bullet points work best for informational items that do not require specific responses—such as status updates, features, or options—because bullets signal that items are related but not sequential. Numbered lists are preferable when recipients must respond to multiple requests or follow procedural steps, as the numbering allows them to reference and answer each item in order, reducing the chance that any request is missed. Lists of three or more items should always be broken out from paragraph text to improve scannability. Email formatting directly impacts compliance with accessibility standards such as WCAG 2.2 and Section 508. These guidelines require specific text presentation criteria including line height at least 1.5 times the font size, paragraph spacing at least twice the font size, adequate color contrast ratios, and text width limited to 80 characters to prevent overly long lines. Semantic HTML elements for headings and lists help screen readers navigate content, while alt text for images ensures that non-visual users can access all information. Organizations in regulated industries such as healthcare, finance, and government must ensure their email formatting meets these standards to avoid excluding people with disabilities and potentially violating legal requirements. Yes, Mailbird's email template feature allows content creators to save well-formatted message structures and reuse them for recurring communications. Templates can encode best practices such as short paragraphs, clear headings, appropriate lists, and accessible formatting defaults. Users can create templates by composing an email draft, clicking the Email Templates icon, selecting "Save draft as template," and providing a name and subject. When templates embody readability principles—including meaningful subject lines, introductory paragraphs that summarize purpose, list-based sections for tasks, and closing paragraphs with next steps—they significantly improve consistency and reduce cognitive burden for both senders and recipients. Accessibility research and client documentation recommend using familiar sans-serif fonts such as Arial or Calibri, which are easier to read on screen, with font sizes large enough to be comfortably legible—especially on mobile devices where text may appear small. Line height should be approximately 1.5 times the font size, and paragraph spacing should be at least twice the font size to provide clear visual separation. Text should not be justified to both margins, as this creates irregular spacing that hinders reading. High color contrast between text and background is essential, following WCAG's quantitative thresholds. Conservative HTML formatting that respects cross-client constraints ensures that spacing and fonts remain readable when emails are viewed in different clients and on various devices.Why Email Formatting Matters More Than Ever
