The fastest way to unblock someone in Gmail

Open Gmail and go to Settings (the gear icon in the top right). Click See all settings, then select the Filters and Blocked Addresses tab. Find the sender you want to unblock in the list, click the checkbox next to their address, and click Unblock. The person's emails will now arrive in your inbox instead of being filtered out.

If you have only a few blocked addresses, you can also unblock directly from an email. When you receive a message from someone you blocked, Gmail shows a notification at the top saying they're blocked. Click Unblock [sender name] and confirm. This takes about five seconds and works the same way as the Settings method.

After you unblock, their future emails come through normally. Emails they sent while blocked do not automatically reappear — you would need to search for them manually if you want to read old messages.

Key Takeaways

  • You can unblock an address in Settings under Filters and Blocked Addresses, or directly from any email they send you.
  • Unblocking takes effect when ready for new emails, but old messages from when they were blocked stay hidden unless you search for them.
  • If you unblock someone by mistake, you can block them again the same way.
  • Unblocking in Gmail does not affect your contact list or any other Google service — it only changes your Gmail inbox rules.

Where Gmail stores your blocked list

Your blocked addresses live in the Filters and Blocked Addresses tab inside Settings. This is the central place Gmail keeps all the senders you have blocked, whether you blocked them from an email, from a contact card, or by creating a filter. You can see the full list at any time and unblock multiple people in one session.

The list shows the exact email address you blocked. If someone has multiple email addresses and you only blocked one of them, their other addresses will still reach your inbox. You would need to block each address separately if you want to block all of them.

Unblocking from an email versus Settings

Both methods do the same thing, so choose whichever is closer to what you are doing right now. If you just received an email from someone and want to unblock them when ready, the notification at the top of the message is faster — one click and you are done. If you want to review your entire blocked list or unblock several people at once, Settings is the better choice.

In Settings, you can see all your blocked addresses in one place and unblock them in bulk by checking multiple boxes and clicking Unblock once. From an individual email, you can only unblock that one sender at a time.

What happens to old emails after you unblock

When you block someone in Gmail, their future emails go to spam or are filtered out entirely, depending on how you blocked them. Unblocking stops that filter, so new emails arrive normally. However, emails they sent while they were blocked do not automatically move back to your inbox — they stay wherever Gmail put them.

If you want to read old messages from someone you just unblocked, search for their email address in the search bar at the top of Gmail. You can then move those messages to your inbox if you want to keep them. This is useful if you blocked someone by mistake and want to catch up on what you missed.

Blocking someone again if you change your mind

If you unblock someone and then decide you want to block them again, the process is the same as the first time. Open any email from that person and click the three dots menu, then select Block [sender name]. Or go back to Settings, find their address in your contacts or recent senders, and create a new block.

Gmail does not penalize you for blocking and unblocking the same person multiple times. You can change your mind as often as you need to.

Unblocking does not affect other Google services

Blocking someone in Gmail only affects your Gmail inbox. It does not block them from your Google Calendar, Google Meet, Google Drive, or any other Google product. If you want to prevent someone from seeing your calendar or contacting you through Meet, you need to adjust the settings in those services separately.

Similarly, if you have blocked someone's phone number in your phone's contacts or blocked them on another email service, unblocking them in Gmail does not change those settings. Each service keeps its own block list.

Frequently Asked Questions

Can I unblock someone if I deleted their email?

Yes. Go to Settings, click Filters and Blocked Addresses, find their address in the list, and click Unblock. You do not need to have an email from them to unblock them — the block list is separate from your inbox.

What if I blocked someone but do not remember their email address?

Open Settings and go to Filters and Blocked Addresses. Your entire blocked list is there. Scan through it to find the person, or use your browser's find function (Ctrl+F on Windows, Cmd+F on Mac) to search the page if the list is long.

Does unblocking someone let them see old emails I sent them?

No. Unblocking only affects what reaches your inbox going forward. It does not change any emails you already sent or received. The person you unblock cannot suddenly see messages you deleted or anything else in your account.

Can I block someone without them knowing?

Yes. When you block someone in Gmail, they do not receive a notification. However, if they try to email you and their message bounces back or disappears, they may figure it out. Gmail does not tell them they are blocked.
