The fastest way to block an email sender on iPhone

Open the email you want to block in the Mail app, tap the sender's name or email address at the top of the message, then tap Block This Contact. That sender's future emails will go straight to your trash folder. You can also swipe left on an email in your inbox, tap the trash icon, then tap Block when the option appears.

Once you block someone, their emails stop showing up in your inbox when ready. If you change your mind later, you can unblock them by going to Settings > Mail > Blocked Contacts and swiping left on the name you want to remove.

Key Takeaways

  • Blocking an email sender takes two taps in the Mail app and sends their future messages to trash automatically.
  • Blocked emails are not deleted — they go to your trash folder so you can review them later if needed.
  • You can unblock a contact at any time through Settings > Mail > Blocked Contacts.
  • Blocking works across all your Apple devices if you use the same iCloud account.
  • Blocked senders cannot tell they have been blocked, and blocking does not affect emails already in your inbox.

Where blocked emails go

When you block someone on iPhone, their emails do not disappear — they move to your trash folder instead. This means you can still read them later if you need to, but they will not clutter your inbox or send you notifications.

The trash folder keeps deleted emails for 30 days before removing them permanently. If you want to permanently delete a blocked sender's emails right away, you can go to your trash folder, find their messages, and delete them manually.

Blocking emails from the same domain

If you are getting unwanted emails from multiple addresses at the same company or domain (like spam@company.com, noreply@company.com), blocking one address at a time is slow. Instead, you can create a VIP list rule or use Mail's filtering options to handle them together.

Go to Settings > Mail > Rules and create a new rule that automatically moves emails from that domain to trash. You can set it to match any sender whose email ends with @company.com, which catches all addresses from that organization without blocking individual people.

Blocking emails on other Apple devices

If you use an iPhone, iPad, and Mac with the same iCloud account, blocking a contact on one device blocks them on all of them. The block syncs automatically through iCloud, so you do not have to block the same person multiple times.

On a Mac, you can block a sender by opening their email in Mail, clicking the sender's name, and selecting Block Contact from the menu. On iPad, the process is the same as iPhone — tap the sender's name and choose Block This Contact.

What happens when you block someone

Blocking prevents that sender's emails from reaching your inbox, but it does not delete emails they already sent you. Those messages stay in your inbox unless you delete them manually. Only new emails from that sender go to trash.

The blocked person cannot tell they have been blocked — they will not receive a notification, and their emails will not bounce back to them. From their perspective, they straightforward will not know whether you read their messages or not.

Unblocking a contact

To unblock someone, open Settings on your iPhone, go to Mail, scroll down and tap Blocked Contacts, then swipe left on the name you want to unblock and tap Unblock. That person's future emails will go back to your inbox normally.

Unblocking does not restore their old emails to your inbox — those remain in trash unless you move them back manually. If you want to see their previous messages, go to your trash folder, find their emails, and move them back to your inbox or another folder.

Using VIP and filtering instead of blocking

If you want to hide emails without fully blocking someone, you can use Mail's VIP feature or create a filter. VIP lets you mark certain senders as important so their emails stand out, or you can create a rule that automatically files emails from someone into a specific folder instead of trash.

To create a filter, go to Settings > Mail > Rules, tap Add Rule, and set conditions like "from contains" with the sender's email address. Then choose an action like "Move to Folder" and pick where those emails should go. This keeps them out of your inbox without deleting them.

Frequently Asked Questions

Can I block emails from a group or mailing list?

Yes, you can block the email address that sends the group messages, but blocking one address does not stop other senders in the group. If the group uses a single address like team@company.com, blocking that address stops all emails from that group. If multiple people send from different addresses, you would need to block each one separately.

What if I block someone by mistake?

Go to Settings > Mail > Blocked Contacts, find the person's name, swipe left, and tap Unblock. Their future emails will go back to your inbox. Any emails they sent while blocked are still in your trash folder — move them back to your inbox if you want to read them.

Do blocked emails take up storage space?

Yes, blocked emails in your trash folder count toward your iCloud storage until you delete them permanently. If you want to free up space, go to your trash folder, find the blocked sender's emails, and delete them. After 30 days, trash empties automatically.

Can I block emails on iPhone without using iCloud?

The blocking feature works with any email account set up in the Mail app, not just iCloud. Whether you use Gmail, Outlook, Yahoo, or another provider, you can block senders the same way. However, the block only works on your iPhone — it does not sync to other devices or email clients unless they also support blocking.

Will blocking stop spam or marketing emails?

Blocking stops emails from one specific address, so it works well for individual senders or known spam accounts. For large-scale spam or marketing lists, blocking one address at a time is slow. Instead, look for an unsubscribe link at the bottom of marketing emails, or create a Mail rule to automatically move emails from that domain to trash.
