The fastest way to block an email address

Most email services let you block a sender in one or two clicks from the message itself. Open the email from the person you want to block, look for a menu icon (usually three dots or a downward arrow) near the sender's name or at the top right of the message, and select "Block" or "Block sender". The exact wording and location depend on which service you use, but the option is almost always there without digging through settings.

Once you block someone, their emails go straight to spam or a blocked folder instead of your inbox. You won't see notifications when they send you something. If you change your mind later, you can unblock them the same way — find the blocked message (usually in spam or a dedicated blocked senders list), open the menu, and choose "Unblock".

Key Takeaways

  • Blocking a sender takes seconds: open their email, tap the menu icon, and select "Block sender" or similar.
  • Blocked emails land in spam or a blocked folder, and you get no notification when they arrive.
  • The steps differ slightly between Gmail, Outlook, Yahoo, and Apple Mail, but all have a block option in the message menu.
  • Unblocking is just as straightforward — find the blocked message and reverse the action from the same menu.
  • Blocking stops individual addresses, not entire domains, so a sender using a different email address can still reach you.

How to block in Gmail

Open the email from the sender you want to block. Click the three-dot menu icon at the top right of the message. Select "Block [sender's name]" from the dropdown. Gmail will move that message to spam and send all future emails from that address to your spam folder automatically.

To unblock, go to your spam folder, find an email from that sender, open it, click the three-dot menu, and select "Unblock [sender's name]". Their emails will return to your inbox as normal.

How to block in Outlook (web and desktop)

In Outlook on the web, open the email and click the three-dot menu at the top right. Select "Block" or "Junk" depending on your version, then confirm. On the Outlook desktop app for Windows or Mac, right-click the sender's name in the email and choose "Block Sender". Outlook moves blocked messages to your junk folder.

To unblock in the web version, go to Settings (the gear icon), then "Mail" > "Junk email", and look for a list of blocked senders. Find the address and remove it. On the desktop app, go to File > Options > Trust Center > Junk Email and manage your blocked list there.

How to block in Yahoo Mail

Open the email from the sender. Click the three-dot menu icon and select "Block". Yahoo moves that sender's emails to spam. You can also hover over the sender's name and click the block icon that appears.

To unblock, go to Settings (the gear icon in the top right), then "Security and privacy" > "Blocked addresses". Find the sender you want to unblock and click the X next to their name.

How to block in Apple Mail and iCloud Mail

In Apple Mail on Mac, right-click the sender's name or email address and select "Block Contact". On iPhone or iPad, open the email, tap the sender's name at the top, then tap "Block this Contact". In iCloud Mail on the web, click the three-dot menu and select "Block sender".

Blocked senders' emails go to your junk folder. To unblock on Mac, open Preferences > Junk Mail, find the blocked address, and remove it. On iPhone or iPad, go to Settings > Mail > Blocked Contacts and swipe left to delete. In iCloud Mail, go to Settings > Mail > VIP and Blocked, then remove the address from the blocked list.

What blocking does and does not do

Blocking stops emails from reaching your inbox, but it does not erase messages already there — those stay in your inbox unless you delete them. Blocking one email address does not block the entire domain, so if someone has multiple email accounts or uses a different service, they can still send you messages from those other addresses.

Blocking is not the same as reporting spam. When you block, you are just filtering out one sender. When you report spam, you tell your email service that the sender is sending unwanted bulk mail, which helps protect other users. Some email services let you do both at once — block the sender and report them as spam.

When to block versus when to report spam

Block a sender when you know them personally or recognize the address and straightforward do not want to hear from them anymore. Block a coworker you are avoiding, an ex-partner, or someone who keeps emailing after you have asked them to stop.

Report as spam when you do not recognize the sender, when they are sending you unsolicited sales pitches or phishing attempts, or when the email looks like a scam. Reporting helps your email service identify patterns and protect other users. Many services let you report and block in one action, so you can do both at the same time.

Frequently Asked Questions

Will the sender know I blocked them?

No. Your email service does not notify the sender that you blocked them. They will not receive a bounce-back message or any other confirmation. They may eventually notice that their emails are not getting replies, but they have no way to know for certain that you blocked them rather than straightforward ignoring them.

Can I block an entire email domain instead of just one address?

Most standard email services do not have a built-in option to block an entire domain from the message menu. You would need to access advanced filters or rules in your settings. Gmail, Outlook, and Yahoo all let you create filters that automatically send emails from a specific domain to spam, though the steps vary. Check your email service's help section for "create a filter" or "email rules" to set this up.

What happens to emails from blocked senders if I unblock them later?

Emails that arrived while the sender was blocked stay in your spam or blocked folder — unblocking does not move them back to your inbox. New emails from that sender will go to your inbox as normal once you unblock. If you want to see the old messages, you will need to go to spam and move them manually.

Can I block emails on my phone the same way as on a computer?

Yes, but the steps are slightly different. On iPhone or Android, open the email, tap the sender's name or the menu icon, and look for "Block" or "Block sender". The option is usually in a menu at the top or bottom of the screen. Desktop versions often have the option in a three-dot menu, while phone versions may require you to tap the sender's name first.

If someone emails me from a different address after I block them, will that new email be blocked too?

No. Blocking works on a per-address basis. If you block jane@example.com, emails from jane@anotherdomain.com will still reach your inbox. If the same person keeps contacting you from multiple addresses, you will need to block each address separately, or create a filter rule that catches emails based on the sender's name or other details.
