How to Forward Gmail Messages to Another Email Client
When you use filters to forward your email messages, you can only forward messages that meet certain criteria to external addresses. If you prefer to read your email in another app or web interface, forward all the Gmail messages you receive to any email address you choose. From now on, email messages that arrive at your Gmail account (minus any spam) are copied to the other account.
Keep Gmail’s copy in the Inbox instructs Gmail to leave the original message in your Gmail inbox as new and unread. Mark Gmail’s copy as read leaves messages in the Gmail inbox but marks messages as read. Archive Gmail’s copy is probably the most useful setting. It instructs Gmail to mark forwarded messages as read, remove messages from the inbox, and keep messages in the archive for later search and retrieval. Delete Gmail’s copy allows the messages to move to the Trash folder after being forwarded. Trashed messages are deleted automatically after 30 days. This is not recommended, as keeping your messages in Gmail is an easy way to back it up.
