The steps depend on which email service you use

Unblocking an email address works differently in Gmail, Outlook, Yahoo Mail, and Apple Mail. The fastest way is usually to find the blocked sender in your settings, locate their address, and click unblock. Most services let you do this in under a minute without restarting your email or changing any passwords.

If you blocked someone by accident, or they have changed and you want to hear from them again, unblocking restores their messages to your inbox. Any emails they sent while blocked will not appear — those are gone. Going forward, their new messages will arrive normally.

Key Takeaways

  • Gmail stores blocked senders in Settings under Filters and Blocked Addresses, where you can unblock them one at a time.
  • Outlook and Yahoo Mail keep blocked senders in a separate list you reach through Settings, and unblocking takes one click.
  • Apple Mail blocks addresses through VIP or rules, and unblocking means removing them from that rule or list.
  • Unblocking does not recover emails sent while the address was blocked — only future messages will arrive.

Unblocking in Gmail

Open Gmail and click the gear icon in the top right corner, then select See all settings. Go to the Filters and Blocked Addresses tab. Scroll down to find the section labeled Blocked addresses. You will see a list of every address you have blocked.

Find the address you want to unblock and click the Unblock link next to it. Gmail will ask you to confirm. Click Unblock again, and the address is now unblocked. Their future emails will go to your inbox like any other sender.

Unblocking in Outlook

Log into Outlook online or open the Outlook desktop app. Click the gear icon and select View all Outlook settings (online) or go to File > Options > Trust Center > Trust Center Settings (desktop). Look for Junk email or Blocked Senders.

You will see a list of blocked addresses. Find the one you want to unblock, select it, and click Remove or the trash icon. Outlook will remove them from the blocked list when ready. If you use the Outlook mobile app, go to Settings > Mail > Junk email to find the same list.

Unblocking in Yahoo Mail

Click the gear icon in the top right and select Settings. Go to the Security and privacy tab. Scroll down to Blocked addresses and you will see every address you have blocked.

Click the X or Remove button next to the address you want to unblock. Yahoo Mail will remove them from the list right away. Their emails will arrive in your inbox from that point forward.

Unblocking in Apple Mail and iCloud Mail

In Apple Mail on Mac, go to Mail > Preferences > Rules. Look for any rule that blocks the address you want to unblock. Select it and click Delete. If you blocked the address by marking it as junk repeatedly, you may need to go to Mailbox > Junk Mail > Reset Junk Mail Filters to clear the block.

In iCloud Mail (iCloud.com), click the gear icon and go to Settings > Mail > VIP or Rules. If the address is listed as blocked in a rule, edit or delete that rule. If you blocked them through the VIP list, remove them from there. On iPhone or iPad, go to Settings > Mail > Blocked and swipe left on the address to delete it.

What happens after you unblock

Once you unblock an address, that sender's emails will arrive in your inbox normally. You will not see any messages they sent while they were blocked — those are permanently deleted. If you want to hear from them again but are not sure, you can always block them again later.

If you unblocked someone by mistake, you can block them again using the same settings where you unblocked them. The process takes the same amount of time in reverse.

If you cannot find the blocked address

Some email services move blocked senders to spam or junk automatically, rather than keeping a separate blocked list. If you cannot find the address in your blocked senders list, check your spam or junk folder to see if their emails are there. You can unblock them by marking a message from that sender as Not spam or Not junk.

If the address still does not appear in your blocked list, they may not be blocked at all — their emails might be caught by spam filters instead. Try sending them a test email to see if they receive it, or ask them to check their spam folder if they are trying to reach you.

Frequently Asked Questions

Will unblocking recover emails they sent while blocked?

No. Emails sent while an address was blocked are deleted and cannot be recovered. Unblocking only affects future messages from that sender. If you need to see what they sent, you would have to ask them to resend it.

Can I unblock someone on my phone?

Yes. On iPhone or Android, open your email app, go to Settings, and look for Blocked Senders or Blocked Addresses. The exact path varies by app, but most let you swipe or tap to remove a blocked address. Desktop is usually faster if you have many blocked senders.

What if I block and unblock someone repeatedly?

You can block and unblock the same address as many times as you need. There is no limit, and it does not affect your account. Each time you unblock, their future emails will arrive normally again.

Does unblocking them mean they can see I unblocked them?

No. Unblocking is invisible to the other person. They have no way to know whether you have blocked or unblocked them. They only know if their emails stop arriving or start arriving again.

Can I unblock a whole domain instead of one address?

Most email services block individual addresses, not entire domains. If you want to unblock everyone from a company domain, you would need to unblock each address separately, or check whether you set up a filter rule that blocks the whole domain — those can sometimes be edited to allow specific addresses through.
