Postbox Review

The Postbox app is a powerful, feature-rich email client that, despite its short time on the market, has gained much popularity. The simple, clean user interface streamlines the management of your email accounts and inbox. The email client also connects to third-party apps, including Evernote, Slack, Todoist, Salesforce, Mailchimp, and more.

“Why are people searching for alternatives to the Postbox app then?” you may think.

Unfortunately, all the nice features come at a price of $40 per license, per version (i.e., Postbox 5, Postbox 6), though there are discounts for multiple uses. It can be hard to justify the cost of Postbox, especially with many free alternative email clients available for any OS on the market.

Perhaps you’ve read multiple Postbox reviews and decided to try the free trial but found that the features and experience didn’t justify the cost. Or you’re a current Postbox user but have realized you don’t utilize all the features. Maybe you need more licenses and don’t want to shell out the additional cash.

Whatever reason you may have for switching to another email client, we’ve compiled a few recommendations for alternatives to Postbox you can try below!

The Roundup of Top Postbox Alternatives

Mailbird vs Postbox

The Postbox email app and Mailbird share many similarities. Mailbird also has a clean interface designed to streamline the user experience and make managing your inbox easier. You can connect a large library of third-party apps to Mailbird, from messaging apps like Facebook, Twitter, and WhatsApp to task management platforms like Todoist, Evernote, and Asana to Google Calendar and more.

Its Unified Inbox with color indicators allows you to manage multiple email accounts from one Inbox, where you can manage and sort your emails. In addition to that, you can completely customize your layout and color theme to make the experience unique to you.

Thunderbird

Mozilla Thunderbird is a free email client that’s loved by its users due to its advanced customization capabilities. While most email clients come with a set of features built into the program, Thunderbird has a large library of extras you can download and install to extend its capabilities. Examples include calendar add-ons, mail merge capabilities, ad blockers, and more. It’s also kind of easy to set up and includes support for an unlimited number of email accounts.

Benefits of Thunderbird

  • Free to use with quick and easy setup and an unlimited number of email accounts
  • Fully expandable via add-ons and extras in the Thunderbird library
  • Includes other notable features, such as email encryption, advanced security protocols, calendar and task management, and a built-in chat function

WebMail

More than likely, the email clients that are most recognizable to you are the webmail services, such as Gmail, Yahoo, Hotmail, Outlook, etc.

While all the other recommendations on this list are email applications, webmail allows you to access your email anywhere you have an internet connection and on any computer. All you have to do is visit the web address and log into your email.

Of course, this convenience comes at a cost — webmail services are much lighter on features, and you cannot access your inbox offline.

Benefits of Webmail

  • Access your email through a web browser on any computer that’s connected to the internet.
  • Almost always free for personal use, regardless of the company
  • No need to download or install any programs to get access to your email
  • If you choose to use webmail, you can also have an email application on your personal computer that syncs with your account. The combination of both might be the best alternative for you.

Conclusion

It’s clear that the Postbox app offers many advantages, but for most people, they will not outweigh the cost — especially when you get these same advantages from using an email client like Mailbird, for a cheaper price. So whether you’re a paying Postbox user or someone who used the trial and decided to explore alternatives, we hope you found these recommendations helpful.

  • I’d like to use Mailbird, but the compose window has far to few fonts. Why can’t I use all the fonts that are on my system, the way I can with Postbox or Thunderbird?

  • Hungarian translation please! THX!

  • Postbox: CalDAV, Mailbird: nope. A NoGo for me

  • There is no google contacts sync in Mailbird but in Postbox there is a plugin for that.

  • Mailbird is very nice and I’d paid for it, but it does lack the professionality of Outlook / Postbox. The composer windows is too simplistic. Tab doesn’t work that well. When I need to write a professional mail, I simply miss Outlook. Even so with signatures including a picture. Not to speak about lay-outs being messed up when I read my previous mails in the reply’sof my correspondents. Serioulsy inprofessional. When complaining at Mailbird I got the task to confirm with my correspondents if the lay-out was indeed messed up. Come on, you can see that in the screenshot I attached. Just fix it, or say you are working on it…

  • mailbird is a good option only for windows, but not as long as they add support for Mac remains a second option, the first choice is postbox, once implemented an App for Mac, we can again be compared with more force …

    Sorry! I wholeheartedly disagree that Mailbird can be the best alternative to Postbox as Postbox is multiplatform. Mailbird has snubbed its nose at OSX users for whatever stupid reason. It maybe the most feature rich, have an exemplary layout or even be the best in design but it simply cannot be the best overall as it leaves a HUGE base of power users (paying customers!!!) in the freezing cold.

  • I also bought Mailbird but I’m considering switching to Postbox or Thunderbird, simply because they provide a way better way to search email, plus there is no way to sync contacts in Mailbird. I find those two features to be essential for a proper mail client.

    Damn. Just tried postbox & hated it on sight because of the 1993-style UI. Here, we have something with a decent UI, and… Windows only. Great.

    • Every once in a while they talk about a Linux/OSX port/version, but I haven’t seen anything in a while. When this comes to *NIX it will actually be pretty incredible.

      It already feels like something that would fit right in on a nix workstation

  • Postbox does looks outdated but has some of the best features around and is productivity oriented. I just tried Mailbird and got nothing but problems: No text showing in email content, desktop folder filled with installation files and folder. uninstallation failed and left tons of trash files and registry entries. Now the installer wont even run anymore!
    Mailbird looks modern and all (although the integration with slack, todoist, etc dont not look that great), but it is a badly written very patchy and unstable piece of software. I just waisted close to an hour just installing, uninstalling it and cleaning my computer. In comparison PostBox can run as a portable app and does mess with and system directories or registry.
