Where your blocked list actually lives

When you block an email address, you are telling your email provider to send that person's messages to spam or delete them entirely — the exact behavior depends on which email service you use. Gmail, Outlook, Yahoo Mail, and Apple Mail all have a blocked senders list, but none of them make it equally straightforward to find or change.

The blocked address does not disappear from the internet or stop the person from sending. They can still email you; you straightforward will not see their messages arrive in your inbox. If you change your mind, you need to go into your email settings and remove that address from the blocked list. The steps are different for each service, and some services bury the option deeper than others.

Key Takeaways

  • Blocked emails go to spam or are deleted depending on your email provider, but the sender can still attempt to reach you.
  • Gmail stores blocked addresses in a list you can access through Settings > Filters and Blocked Addresses, while Outlook uses Settings > Mail > Junk Email.
  • Once you unblock an address, future emails from that sender will arrive in your inbox normally, but past blocked messages usually stay deleted.
  • If you cannot find the blocked list in your email settings, searching for "blocked senders" or "blocked addresses" in your provider's help center will show you the exact steps for your account type.

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 email address you have blocked. Find the one you want to unblock and click the Unblock button next to it.

After you unblock the address, emails from that sender will go to your inbox like any other message. Gmail will not automatically retrieve the messages it blocked while the address was on your list — those stay in your spam folder or deleted folder, depending on how you set up the block. If you need to see those old messages, you can search your spam or trash folder by the sender's name.

Unblocking in Outlook

Log into your Outlook account and click the gear icon in the top right. Select View all Outlook settings, then go to Mail > Junk email. Under Blocked senders, you will see the list of addresses you have blocked. Click the minus sign next to the address you want to unblock.

Outlook removes the address from your blocked list when ready. Like Gmail, Outlook does not restore messages that arrived while the address was blocked — you would need to ask the sender to resend anything important. Future emails from that address will land in your inbox unless you have other filters set up that send them elsewhere.

Unblocking in Yahoo Mail and Apple Mail

In Yahoo Mail, click the gear icon, select Settings, then go to Security and privacy > Blocked addresses. You will see your blocked list. Click the X next to any address to remove it from the block list.

In Apple Mail on a Mac, go to Mail > Preferences > Junk Mail. Click the Reset button to clear your entire junk mail filter, or manually drag messages from your junk folder back to your inbox if you want to keep the filter active but restore specific senders. Apple Mail does not have a straightforward blocked senders list like Gmail or Outlook — instead, it learns which addresses are spam based on your actions. If you want to receive mail from someone again, move their messages out of junk and mark them as Not Junk.

What happens after you unblock

Once an address is unblocked, the sender's future emails will arrive in your inbox. You will see them the same way you see mail from anyone else. The email service does not notify the sender that you have unblocked them, so they will not know you have changed your mind unless you tell them.

If the person tried to email you while they were blocked and you want to see those messages, you will need to search your spam or trash folder. Most email services keep deleted mail for 30 days before permanently removing it, so if the block was recent, you may still be able to recover those messages. After 30 days, they are usually gone for good.

Why someone might stay blocked even after you unblock them

If you unblock an address but still do not see emails from that person, check whether you have set up a filter or rule that sends their mail somewhere else. In Gmail, filters can override your blocked list — if you created a filter that sends mail from that address to a label or deletes it, unblocking will not stop the filter from working. Go back to Filters and Blocked Addresses and look for any active filters for that sender.

In Outlook, check your Focused Inbox settings. Outlook can automatically sort mail into a Focused tab and an Other tab, and sometimes legitimate mail ends up in Other by mistake. If you unblock someone and their mail still does not show up in your main inbox, check the Other tab or adjust your Focused Inbox settings to include them.

Blocking and unblocking on mobile devices

On the Gmail app for iPhone or Android, open an email from the sender you want to unblock, tap the three dots menu, and select Unblock [sender's address]. The process is faster on mobile than on the web version because you do not have to navigate through settings.

On the Outlook mobile app, open an email from the blocked sender, tap the three dots, and select Unblock sender. Apple Mail on iPhone does not have a dedicated unblock option — instead, move the sender's messages to your inbox and mark them as Not Junk to train the filter to accept future mail from them.

Frequently Asked Questions

Can I unblock someone without them knowing?

Yes. Unblocking an address is a private action on your account. The sender will not receive a notification that you have unblocked them. They will only know if their emails start arriving in your inbox and you tell them you have unblocked them, or if they notice you are responding to their messages again.

Will I see the emails they sent while they were blocked?

No, not automatically. Those messages are deleted or in your spam folder depending on how you set up the block. You can search your spam or trash folder by the sender's name to find them, but they will not reappear in your inbox on their own. Ask the sender to resend anything important if you need it.

What if I unblock someone and they keep sending unwanted mail?

You can block them again at any time using the same method you used the first time. If the mail is harassing or threatening, you can also report it as spam or abuse to your email provider. Most services have a report button in the email itself or in the three-dot menu.

Do I need to unblock someone to reply to their old emails?

No. You can reply to any email in your inbox or spam folder whether the sender is blocked or not. Blocking only stops new incoming mail from that address. If you have an old email from someone and you want to respond, you can do that without unblocking them first.
