The quickest way to unblock an email address

The steps depend on which email service you use. Gmail, Outlook, and Yahoo each store blocked addresses in a different place, but all three let you unblock someone in under a minute once you find the right menu.

The person you unblock will not be notified. Their emails will start arriving in your inbox again when ready, and you will see any messages they sent while blocked. You can block them again at any time if needed.

Key Takeaways

  • Gmail blocked senders are managed in Settings under Filters and Blocked Addresses, where you can unblock with one click.
  • Outlook stores blocked addresses in the Junk Email settings, accessible from the Home tab or account settings depending on whether you use the web version or desktop app.
  • Yahoo blocks are found in the Settings menu under Blocked Addresses, and unblocking removes them from your blocked list when ready.
  • Unblocking someone does not notify them, and their past emails will appear in your inbox once you unblock.
  • If you cannot find the blocked address list, searching your email provider's help documentation for "unblock" or "blocked senders" will show you the exact steps for your version.

Unblocking someone in Gmail

Open Gmail and click the gear icon in the top right corner, then select See all settings. Click the Filters and Blocked Addresses tab. You will see a list of every address you have blocked. Find the one you want to unblock and click Unblock next to their name.

If the list is long, use your browser's find function (Ctrl+F on Windows, Command+F on Mac) to search for part of their email address or name. Once you unblock them, close the settings page — the change saves automatically.

Unblocking someone in Outlook

The location differs between Outlook on the web and the Outlook desktop app. On the web version, click the gear icon in the top right, then View all Outlook settings. Go to Mail in the left sidebar, then Junk email. You will see a Blocked senders section with a list of addresses. Click the X next to the person you want to unblock.

In the Outlook desktop app, click Home at the top, then Junk in the toolbar, and select Junk Email Options. The Blocked Senders tab shows your list. Highlight the address and click Remove.

Unblocking someone in Yahoo Mail

Click the gear icon in the top right and select Settings. Click Security and privacy in the left menu. Scroll down to Blocked Addresses and you will see everyone you have blocked. Click the X next to the address you want to unblock, then confirm the removal.

Yahoo will ask you to confirm before removing them from the blocked list. Once you confirm, they are unblocked and their emails will reach your inbox again.

What happens after you unblock someone

Emails from that person will arrive in your inbox normally from that moment forward. Any messages they sent while you had them blocked will not appear retroactively — those emails were rejected by your email service and are gone. You will only see new messages they send after you unblock them.

The person has no way of knowing you unblocked them. They will not receive a notification, and there is no record they can see. If they sent emails while blocked and you do not respond, they may assume you never got them, which is technically true from their perspective.

If you cannot find the blocked address list

Email services update their interfaces regularly, so the exact menu location may differ from what is described here. The fastest way forward is to search your email provider's help center for the word "unblock" — Gmail Help, Outlook Support, and Yahoo Help all have articles specific to your version that show screenshots of the exact buttons to click.

You can also search within your email settings using your browser's find function (Ctrl+F or Command+F) for the word "block" to locate the right section. If you use a third-party email client like Thunderbird or Apple Mail, the blocking feature may not exist in that app — you would need to unblock through your email provider's website instead.

Frequently Asked Questions

Will the person know I unblocked them?

No. Unblocking someone sends no notification to them. They have no way to see that you blocked them in the first place or that you have now unblocked them. If they ask why you did not respond to emails they sent, you can tell them you had them blocked by mistake.

Can I see emails they sent while I had them blocked?

No. When you block someone, their emails are rejected before they reach your mailbox. Those messages are deleted by your email service and cannot be recovered. You will only see new emails they send after you unblock them.

What if I block them again later?

You can block and unblock the same person as many times as you want. Each time you block them, new emails from that address will be rejected. Each time you unblock them, their emails will reach your inbox again.

Do I need to do anything else after unblocking?

No. Unblocking is the only step. You do not need to restart your email app or refresh the page. Their emails will start arriving in your inbox when ready, and you can respond to them normally.

What if I unblocked the wrong person by mistake?

You can block them again right away using the same process you used to block them the first time. Go back to your blocked senders list and add them again. Any emails they send after you re-block them will be rejected.
