How to change the default mail app on Mac

Switching the default mail app on your Mac might sound like a small tweak, but it can be a game-changer. Whether you’re more comfortable with Mailbird, Outlook, Thunderbird, or Gmail, selecting your preferred email app as the go-to choice can streamline your workflow.
Let’s be honest: Apple Mail isn’t everyone’s cup of tea. But you have complete control over which app launches as your default email tool, so you don’t have to stick with the status quo.
In this guide, we'll show you exactly how to change your default mail app on Mac and why doing so can improve your daily routine.
What’s a default mail app?
A default mail app is simply the application your Mac uses to handle all email-related tasks, such as opening mailto: links or sending an email directly from another app.
By default, macOS comes pre-installed with Apple Mail, but many users prefer third-party alternatives like Mailbird, Outlook, Gmail, or Thunderbird, especially if they offer better features or smoother integrations.
Apple Mail may be the default choice, but it’s far from the only option. Depending on your needs, switching to an app like Mailbird can provide more customization and productivity options, especially for users juggling multiple accounts or collaborating across platforms. If you're multitasking and find your touchpad not working, a user-friendly email app can help you stay productive with efficient keyboard shortcuts and streamlined navigation.
Why change the default mail app?
There are plenty of reasons you might want to change your default email app on a Mac. Here are a few common ones:
- Unified inbox & simplicity: Mailbird is a great option if you value a streamlined interface and need a unified inbox for multiple email accounts. It’s designed with productivity in mind, smoothly integrating with apps such as Google Calendar, Slack, and Dropbox. This helps simplify your workflow and reduce the need to switch between different platforms. Although known primarily as a Windows app, a Mac version will be available in the fall of 2024.
- Customization & features: Some apps, like Microsoft Outlook, offer more robust scheduling, task management, and integration options. This can be a huge benefit if you're managing work-related emails since Outlook connects seamlessly with Microsoft Teams and other Microsoft 365 productivity tools.
- Integration: If you use Google Workspace, you might find it easier to work with Gmail directly through a dedicated desktop app. It can offer better synchronization and notifications compared to Apple Mail.
- Better performance: Not all email apps are created equal. Some users find that alternatives run faster or use fewer system resources. Mozilla Thunderbird, for example, is known for its lightweight performance, making it a great free alternative for Mac users.
Requirements for changing the default mail app
Before you switch your default mail app, make sure:
- The new email app (e.g., Outlook, Gmail, Thunderbird) is installed and set up on your Mac.
- Your macOS version is compatible with the app. Most popular apps support the latest macOS versions like Ventura or Sonoma, but it’s always good to double-check.
