Some people love the Mail app Preview feature, while others want to know how to turn off Mail Preview.

The iOS 18 Mail app update included an Apple Intelligence feature that gives you email summaries. With iOS 26, you can shrink or enlarge those email summaries.

Here’s how to turn off Mail Preview, as well as how to change the length of the previews you see in the Mail app, so you can get a preview that’s actually helpful for you.

  • Choose anywhere from a one-line to a five-line summary of your emails in the Mail app.
  • Turn off email summaries if you do not find them useful.

This tip was performed on an iPhone 14 Pro running iOS 26.1.
