6. Click OK.

Carefully consider the rules you create. If they’re too broad, messages can be sent inadvertently or create loops (replies to replies you sent). If possible, test the rules.

Redirect emails

1. In the Mail app on your Mac, select the message you want to redirect.

2. Choose Message > Redirect.

3. Address the message, then click the Send button .
