You can automatically forward incoming mail to another email address. You can forward all of your mail, or create a filter to forward mail that meets certain rules.
You must verify that the email address you want to forward mail to is a legitimate recipient. After you add a forwarding address, Gmail sends an email to that address with a link to confirm permission to forward mail.
Tip: If you use Gmail for work or school, Gmail doesn't require you to verify the forwarding address if the email address is for a user or group in your organization.
