Go into account settings and set up mail forwarding from gmail to your new mail provider. Pick a mail provider that has decent control and ability to create custom rules/filters. Just be sure to log into gmail every couple months to ensure your mail forward is still in place and the account is actively used. I did this with a few gmail accounts that I created for vendors that would not permit custom domains, one of a cell company and two for a couple social media sites that did not like custom domains. To save the existing contents of your gmail account, go into account settings and enable IMAPS access. Use an IMAP client to pull down the emails. You can use IMAP to push them up to your new provider should you wish to keep emails on a server.
