To make Gmail forward incoming messages to another email address automatically:
- Sign in to your Gmail account.
- Click “Setting” on top right of the page.
- Go to “Forwarding and POP/IMAP” tab.
- In the “Forwarding” column, click the radio button next to “Forward a copy of incoming mail to”.
- Enter the email address in the box that you want to forward the mail to.
- Gmail will keep every copy of your mail in its inbox (default setting), click the pull-down menu to change this behaviour to either trashes or archives the email after it has been forwarded. “Archive Gmail’s copy” option will make Gmail mark forwarded emails as read and remove them from inbox but keep the emails in the archive for later search and retrieval. The last option “Trash Gmail’s copy” will make Gmail move the forwarded messages to “Trash” after they have been forwarded. All the Trashed messages will be permanently deleted automatically after 30 days.
- Click “save changes” and you are done.
