Creating a Rule to Block Email From a Sender

Here's how to build a rule to block messages from a specific sender:

  1. Go to Mail > Preferences from the Mail menu bar.

    Mail Preferences selected on a Mac

    If you already have a message from the sender you want to block, open the email first and then select Mail > Preferences to avoid having to type the address when you formulate the rule.

  2. Click the Rules tab in the Preferences screen and select Add Rule.

  3. In the rule form, choose any of the following conditions if only one of the criteria must be met to trigger the rule; this is the default setting. If all the conditions you specify must be met, choose all instead. The criteria fields are From and contains.

  4. Type the full email address that you want to block in the field next to contains.

    If you started this process by opening an email from the email address you wanted to block, you don't have to type in the email address. It will already be filled in.

    To block an entire domain and not just a single email address from that domain, enter the domain only in the field next to contains. For example, you can block all @example.com email addresses by entering example.com in the field.

  5. Select Delete message under Perform the following actions.

Mac Mail lets you block senders by other conditions, too, such as messages in which the Subject line contains specific text. This approach is useful if you often receive emails from different senders that have the same text in the Subject line, and you want to block all of them.
