To forward your Gmail to another email account, go to account settings and click "Forwarding and POP/IMAP". Select "Forwarding" and add the forwarding address, then confirm the request. You can cancel forwarding at any time. You can also add an automatic signature with your name and links under the "General" tab. Signatures only apply to emails sent from Gmail unless also configured in the other email client. Additionally, you can send emails from Gmail displaying a different "from" address like your domain address by selecting "Send mail as" and verifying ownership of the other email.
