How to block email senders on iPhone

iOS Mail

One of the built-in features of iOS can easily block specific phone numbers on the iPhone. When a phone number is blocked, it prevents incoming voice calls, messages and FaceTime from getting through. Mail senders can also be blocked, with the Mail app recognizing blocked email addresses and ignoring them.

To block spam or otherwise annoying emails from your inbox, follow these steps on an iPhone, iPad or iPod touch running iOS 13 or later:

  1. Launch the Phone app and tap Contacts
  2. Add a new Contact with the plus (+) button
  3. Enter the email address to block
  4. Block email iOS contact 1
  5. Scroll down and tap Block this Caller
  6. Block email iOS contact 2
  7. Confirm by selecting Block Contact from the pop-up menu
  8. Block email iOS contact 3
  9. Navigate to Settings and tap Mail
  10. Block email iOS contact 4
  11. Toggle Ignore Blocked Senders -> ON (green switch)
