To block senders in iCloud Mail from a browser (iCloud.com), you can't use a direct "Block Sender" button like in the Mail app; instead, create a Rule in Mail Settings to automatically move emails from a specific address to the Trash. Sign into iCloud.com, go to Mail Settings (gear icon) > Rules, then Add Rule, set the condition to "Is From" with the sender's email, and choose the action "Move to Trash".
Steps to Create a Rule in iCloud Mail (Browser)
- Go to iCloud.com: Open Safari, go to iCloud.com, and sign in with your Apple ID and password.
- Open Mail: Click the Mail icon to open iCloud Mail.
- Access Settings: Click the gear icon (Settings) in the bottom-left corner, then select Rules.
- Add a Rule: Click Add a Rule....
- Set Conditions:
- In the "If a message" section, choose is from from the dropdown menu.
- Type the full email address you want to block in the text field.
- Set Action:
- In the "Then" section, choose Move to Trash.
- Confirm: Click Done to save your new rule.
Now, any email from that specific address will automatically be moved to your Trash folder, preventing it from cluttering your Inbox.
