How to Set Your Preferred Email Client in macOS Catalina

Catalina Quick Tip

When you click a link for an email address, your Mac opens the app you’ve set for that kind of link. Mail is the default email app, and it works just fine for me.

However, if you install other email apps, you might want to set them to open when you click an email link or web link. To set a default email app:

  • Open the Mail app.
    If you haven’t already set up an email account in Mail preferences or Internet preferences, follow the onscreen instructions to set one up.
  • From the Mail menu, choose Preferences.
  • Click General.
  • Choose your email app from the ”Default email reader” pop-up menu. 

If you haven’t installed a new email app on your Mac, only “” will show up.

A bit of trivia: a couple of years ago, you could also reset your default web browser from the Mail app. That feature seems to have disappeared with macOS Catalina.

These instructions apply, for the most part, to other versions of macOS besides Catalina. However, I’m using Catalina on a 16-inch MacBook Pro for this tutorial.
