Block an email address in iCloud Mail on your computer

Open iCloud Mail in your web browser and find the message from the sender you want to block. Click the message to open it, then look for the three dots or gear icon in the top right corner of the email. Select Block Contact or Block Sender from the menu that appears.

Once you block a sender, all future emails from that address go straight to your Junk folder automatically. iCloud remembers the block even if the sender changes their display name — it blocks based on the actual email address. If you change your mind later, you can unblock them by going to iCloud Mail settings, finding the blocked senders list, and removing the address.

The block takes effect when ready. Any emails already in your inbox from that sender stay where they are — blocking only stops new messages from arriving in your main folders.

Block an email address on iPhone or iPad

Open the Mail app and find the email you want to block. Swipe left on the message (or tap and hold it), then tap the trash icon or the three dots menu. Look for an option that says Block Sender or Report Junk. Tap it to block that address.

On some versions of iOS, you may see a popup asking whether you want to block the sender and report the email as junk. Confirm your choice, and the sender is blocked across all your Apple devices that use the same iCloud account. The block syncs automatically — you do not need to block the same address on each device separately.

If you do not see a block option in the menu, try swiping all the way to the left on the message. Sometimes the block button appears only when you swipe fully to reveal all actions.

Key Takeaways

  • Blocking a sender in iCloud Mail sends all future emails from that address to your Junk folder automatically.
  • On your computer, open the email, click the three dots or gear icon, and select Block Contact or Block Sender.
  • On iPhone or iPad, swipe left on the message and tap Block Sender from the menu that appears.
  • Blocks sync across all your Apple devices that share the same iCloud account, so you only need to block once.
  • Emails already in your inbox from a blocked sender remain there — blocking only stops new messages.

Find your blocked senders list

On your computer, go to iCloud Mail settings by clicking the gear icon in the top right corner of the mail window. Look for Settings or Preferences, then find the section labeled Blocked or VIP. Your blocked senders list appears there with all the addresses you have blocked.

From this list, you can remove any block by clicking the X or delete button next to the sender's address. Unblocking a sender means their emails will no longer go to Junk — they will arrive in your inbox like any other message.

On iPhone or iPad, you cannot view your full blocked list in the Mail app itself. Instead, go to Settings on your device, tap Mail, then scroll down and tap Blocked to see all blocked senders and remove any blocks you no longer want.

What happens when you block someone

When you block a sender in iCloud Mail, that address is added to your blocked list, and all emails from them automatically go to your Junk folder. The sender does not receive a notification that you blocked them — they will not know unless they notice their emails are not getting replies.

If the sender uses multiple email addresses, you will need to block each address separately. Blocking one address does not block their other accounts. Similarly, if a sender creates a new email address after you block them, that new address is not automatically blocked — you would need to block it when you receive an email from it.

Blocked emails still count against your iCloud Mail storage, so if you want to free up space, you can delete them from your Junk folder rather than just letting them pile up there.

Unblock a sender if you change your mind

Go to your blocked senders list using the steps above for your device. Find the address you want to unblock and click or tap the remove button next to it. Confirm the action if prompted. The sender is now unblocked, and their emails will arrive in your inbox normally again.

Unblocking takes effect right away. If the sender has been emailing you while blocked, those messages are still in your Junk folder — unblocking does not move them back to your inbox automatically. You can move them manually if you want to see them, or leave them in Junk and delete them.

Report spam instead of just blocking

If an email is spam or phishing rather than just unwanted, you have the option to report it to Apple in addition to blocking it. When you block a sender on iPhone or iPad, you often see a choice to Block and Report Junk. Choosing this option sends a copy of the email to Apple so they can identify spam patterns and improve their filters for all users.

On your computer, you can report spam by clicking the flag or report icon in the email before or after blocking. Reporting helps Apple's systems learn which senders are sending spam, so future emails from similar addresses may be caught automatically for other users.

Reporting spam does not change what happens to that sender's emails in your account — they still go to Junk. But it contributes to making iCloud Mail safer for everyone by helping Apple identify new spam sources.

Frequently Asked Questions

Can a blocked sender tell that I blocked them?

No. A blocked sender does not receive any notification from iCloud. They will not know you blocked them unless they notice you are not responding to their emails or they check their own email delivery reports.

If I block someone, do their old emails disappear from my inbox?

No. Blocking only affects new emails going forward. Any messages from that sender that are already in your inbox stay there. You can delete them manually if you want them gone, or leave them and just ignore them.

What is the difference between blocking and reporting spam?

Blocking stops emails from a sender from reaching your inbox — they go to Junk instead. Reporting spam does the same thing but also sends information to Apple to help them improve spam detection. You can do both at the same time on most devices.

Will blocking someone on iCloud Mail also block their text messages?

No. Blocking an email address in iCloud Mail only affects email. It does not block text messages, FaceTime calls, or any other communication method. You would need to block them separately in each app.

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

iCloud Mail does not have a built-in feature to block entire domains at once. You have to block individual email addresses. If you receive many emails from the same domain, you can block each address as they arrive, or use mail rules to filter them if your iCloud plan supports that feature.
