Where to find the unblock option depends on which email service you use

The steps to unblock someone differ between Gmail, Outlook, Yahoo Mail, and Apple Mail. Gmail and Outlook let you unblock from settings or directly from a blocked sender's message. Yahoo Mail requires you to go through Account Info. Apple Mail on Mac uses System Settings rather than the mail app itself. The fastest route is usually to search your email settings for "blocked" or "blocked senders" — most services put the list in the same place.

If you cannot find where you blocked the person, start by checking whether the email is actually blocked or just filtered into spam or a folder you do not check regularly. Many people think they have blocked someone when the mail is straightforward being sorted automatically. You can test this by asking the person to send you a message and watching for it in your spam folder.

Key Takeaways

  • Gmail unblocking happens in Settings under Filters and Blocked Addresses, or by opening a blocked sender's message and clicking the unblock option.
  • Outlook users should go to Settings, then Mail, then Junk Email, and select Blocked Senders to find and remove the address.
  • Yahoo Mail requires you to sign in to your account on the web, go to Account Info, then Security and Privacy, then Blocked Addresses.
  • Apple Mail on Mac does not have a block feature in the app itself — blocking happens in System Settings under Mail, so you unblock there too.
  • After unblocking, check your spam folder for a few days in case the email system has learned to filter that sender automatically.

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. You will see a list of every address you have blocked. Find the one you want to unblock and click Unblock next to it.

Alternatively, if you have a recent message from that person, open it and look for the three-dot menu icon in the top right of the message. Click it and select Unblock [sender's name]. This method works even if you do not remember exactly how you spelled their address.

Unblocking in Outlook

Sign in to your Outlook account on the web. Click the gear icon in the top right and select View all Outlook settings. Go to Mail, then Junk email. You will see a section called Blocked Senders with a list of addresses. Find the person you want to unblock and click the minus sign or delete icon next to their name.

If you are using Outlook on your desktop or phone, the path is slightly different. On desktop, go to Home, then Junk, then Block Sender, and you will see an option to manage your blocked list. On the Outlook mobile app, open a message from the blocked sender and look for the block or report option — tapping it again will give you the choice to unblock.

Unblocking in Yahoo Mail

Yahoo Mail blocks happen at the account level rather than in the mail app. Go to Yahoo.com, sign in, and click your account icon in the top right. Select Account Info. On the left side, click Security and Privacy, then scroll down to Blocked Addresses. You will see the full list of blocked senders. Click the X next to the address you want to unblock.

If you do not see a Blocked Addresses section, check whether you have blocked the sender at the filter level instead. Go back to Account Info, select Mailboxes, then look for any filters you created that might be sending their mail to spam or trash automatically.

Unblocking in Apple Mail on Mac

Apple Mail does not have a dedicated block feature inside the Mail app. Instead, blocking happens through your Mac's system settings. Click the Apple menu, go to System Settings, then Mail. Look for VIP and Blocked or Blocked Senders. You will see a list of addresses you have blocked. Select the one you want to unblock and click the minus button to remove it.

On iPhone or iPad, go to Settings, scroll down to Mail, then VIP and Blocked. Swipe left on the blocked sender's name and tap Unblock. After you unblock, the next message from that person should arrive in your inbox normally.

What happens after you unblock someone

Once you unblock an address, new messages from that person will arrive in your inbox again. However, old messages that arrived while they were blocked usually stay in whatever folder they were sent to — typically spam or trash. You may want to check those folders and move important messages back to your inbox.

Some email systems learn blocking patterns over time. If you blocked someone and their messages went to spam for months, unblocking the address might not when ready stop them from landing in spam. You may need to mark their first few messages as "not spam" to retrain the filter. This usually takes three to five messages before the system stops treating them as spam automatically.

Unblocking when you cannot find the blocked list

If you cannot locate your blocked senders list, the person may not actually be blocked — they might be filtered by a rule you created instead. Search your email settings for the word "filter" or "rules." Many email services let you create automatic rules that send certain senders to spam or a specific folder without technically blocking them.

Another possibility is that you blocked them on a different device or in a different email client. If you use Gmail on both your phone and your computer, blocking on one does not always sync to the other when ready. Try unblocking on the device where you originally blocked them, then wait a few minutes for the change to sync across your accounts.

Frequently Asked Questions

Can I unblock someone without going into settings?

In Gmail and Outlook, yes — if you have a message from the blocked sender, you can usually open it and click an unblock option directly. In Yahoo Mail and Apple Mail, you have to go through account settings or system settings. The direct method is faster if you have a recent message from them.

What if I blocked someone by accident and they keep trying to email me?

Unblock them using the steps above for your email service. Their next message should arrive normally. If you want to prevent them from emailing you in the future, you can block them again, but for now unblocking will let their messages through.

Does unblocking someone let them see that I blocked them?

No. Blocking and unblocking are invisible to the other person. They will not receive a notification that you blocked them or that you unblocked them. They will only know if their messages suddenly start arriving in your inbox after a long silence.

If I unblock someone, will I see the emails they sent while I had them blocked?

No. Messages that arrived while someone was blocked stay in whatever folder they were sent to — usually spam or trash. Unblocking does not recover old messages. You can search for their address in your spam folder and move messages back to your inbox manually if you want to read them.

Can I block and unblock someone multiple times?

Yes. You can block and unblock the same person as many times as you want. There is no limit to how many times you can change your mind. Each time you unblock, their next message will arrive normally.
