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

The steps to unblock an email address are different in Gmail, Outlook, Yahoo Mail, and Apple Mail. Gmail keeps blocked senders in a list you access through Settings. Outlook uses a Junk Email filter where you can manage blocked addresses. Yahoo Mail has a Blocked Addresses section in Account Info. Apple Mail stores blocked senders in your Mail preferences. The fastest way is to search your email service's help documentation for "unblock" plus your provider's name — each one has a slightly different interface, but the process takes less than a minute once you find the right menu.

If you do not remember which service hosts your email account, check the web address in your browser or look at the login page. You can also search your email inbox for a recent message from that provider — the "From" address will tell you which service you use.

Key Takeaways

  • Gmail stores blocked senders in Settings under Filters and Blocked Addresses, where you can unblock them one at a time.
  • Outlook moves blocked emails to the Junk folder and lets you unblock addresses through the Junk menu or by right-clicking a message.
  • Yahoo Mail keeps a separate Blocked Addresses list in your Account Info that you can edit directly.
  • Apple Mail blocks senders through VIP and Mail preferences, and unblocking requires removing them from your blocked list.
  • Unblocking does not delete old messages from that sender — they remain in your Junk or Deleted folder until you manually remove them.

Unblocking in Gmail

Open Gmail and click the Settings gear icon in the top right corner. Select "See all settings," then go to the Filters and Blocked Addresses tab. Scroll down to find the list of blocked email addresses. Click "Unblock" next to the address you want to restore. Gmail will when ready stop filtering that sender's messages to spam, and new emails from them will arrive in your inbox.

If you cannot find the Filters and Blocked Addresses tab, you may be using Gmail's newer interface. In that case, click Settings, then go to the left sidebar and look for "Blocked addresses." The unblock button appears in the same place.

After you unblock an address, messages from that sender will go to your inbox by default. If you want them to skip the inbox and go to a label instead, you can create a filter rule in the same Settings menu.

Unblocking in Outlook

Open Outlook and go to the Home tab. Click "Junk" in the toolbar, then select "Junk Email Options." A window will open with several tabs — click "Blocked Senders." You will see a list of all addresses you have blocked. Select the address you want to unblock and click "Remove." Outlook will when ready stop treating that sender as junk.

Alternatively, if you see a message from a blocked sender in your Junk folder, you can right-click it and select "Junk" > "Never Block Sender." This unblocks them in one step without opening the settings menu.

Unblocking in Outlook does not move old messages back to your inbox — they stay in the Junk folder. You can move them manually if you want to keep them, or leave them where they are.

Unblocking in Yahoo Mail

Log into Yahoo Mail and click your account icon in the top right corner. Select "Account info," then go to "Security and privacy" in the left sidebar. Click "Blocked addresses." You will see a list of all blocked email addresses. Find the one you want to unblock and click the X button next to it. Yahoo will remove it from your blocked list when ready.

After you unblock an address, new messages from that sender will arrive in your inbox normally. Messages that arrived while the address was blocked remain in your Spam folder unless you move them.

Unblocking in Apple Mail

Apple Mail does not have a single "blocked addresses" list like other services. Instead, blocking happens through VIP settings and mail rules. If you blocked someone by removing them from your VIP list, open Mail and go to Preferences (or Settings on newer versions). Click the "VIP" tab, find the person's name in the list, and click the minus button to remove the block.

If you blocked a sender using a mail rule, go to Preferences, click "Rules," find the rule that blocks that address, and click "Delete." This removes the block. You can also edit the rule instead of deleting it if you want to change what it does.

On an iPhone or iPad, blocking and unblocking works differently. Open Mail, find a message from the sender, swipe left on it, tap "More," then tap "Block This Contact." To unblock, go to Settings > Mail > Blocked Contacts and swipe left on the name you want to unblock, then tap "Unblock."

What happens to old messages after you unblock someone

Unblocking an address does not automatically move old messages back to your inbox. Messages that arrived while the sender was blocked stay in your Spam, Junk, or Deleted folder depending on your email service. You can move them manually if you want to keep them, or leave them where they are.

If you want to find old messages from that sender, use your email service's search function. Type the sender's email address in the search box and select the folder where you think the messages ended up — usually Spam or Junk. Once you find them, you can move them to your inbox or another folder.

Why an email might still not arrive after unblocking

If you unblock an address but still do not see messages from that sender, the problem may not be on your end. The sender's email server might be having trouble, their message might have bounced back before reaching you, or they might be sending from a different address than the one you unblocked. Ask the sender to resend the message and confirm they are using the correct email address.

Another possibility is that your email service's spam filter is still catching their messages even though you unblocked them. This happens when the sender's email server has a poor reputation or sends messages that look like spam. You can create a filter rule to send their messages directly to your inbox, bypassing the spam filter entirely. Each email service has a different way to do this — check your provider's help documentation for "create a filter" or "whitelist an address."

Frequently Asked Questions

Can I unblock multiple email addresses at once?

Most email services require you to unblock addresses one at a time. Gmail, Outlook, and Yahoo Mail all have you click an unblock button for each address individually. If you have many blocked addresses, it will take a few minutes, but there is no faster way through the standard interface.

What if I blocked someone by accident and do not remember their email address?

Go to your blocked addresses list in your email service's settings. The list shows every address you have blocked, so you can scan it to find the one you are looking for. If the list is very long, try searching for a partial name or domain if your email service allows it.

Does unblocking someone mean they can see my email address?

No. Unblocking only affects whether their messages reach your inbox — it does not change your privacy settings or let them see anything about your account. They cannot tell whether you have blocked or unblocked them unless you tell them.

If I unblock someone and then block them again, will old messages reappear?

No. Blocking and unblocking only controls where new messages go. Old messages stay in the folder they were in before. If you block someone again after unblocking them, their future messages will go to spam or junk, but the old ones remain where you left them.

Can I unblock an email address on my phone?

Yes, but the steps are different from the web version. On Gmail's mobile app, go to Settings, select your account, tap "Manage your Google Account," go to the Security tab, scroll to "Third-party apps with account access," and manage blocked addresses there. On Outlook mobile, go to Settings, select your account, and look for Junk Email options. Apple Mail on iPhone has a Blocked Contacts list in Settings > Mail that you can edit directly.
