not GP either, but I did the same and migrated to Fastmail. The transition was extremely smooth, and at least for now gmail allows you to set up integration (either forwarding rule or remote retrieval through IMAP) to forward you old e-mail to fastmail. I have it set up to auto tag all incoming gmail mail and move it into a folder that I check occasionally to see if anything interesting came through.

One amazing advantage to using fastmail (or really any real e-mail provider) is that it is trivial to set it up to use your own domain for e-mail, and to do catchall addresses for your domain. I use this feature heavily, using the general strategy of giving every service a different e-mail address. In this way I can sort by incoming to field, and block out anyone who sends spam using rules acting on the to field. This does an amazing job of sorting out things like mailing lists that keep re-adding you or that are worth monitoring but aren't worthy of showing up in my inbox.

Not GP but I did my migration with the same steps from Google Apps to Fastmail. They even have a nice importer that works well.

>> Are you self hosting your email now, or are you using a provider like ProtonMail?

I switched to FastMail, and and added an MX record for the domain I already had to alias the mail adres to that domain. So now I could easily switch to some other e-mail provider at any time in the future. But I’ve been totally happy with FastMail so far.

I did consider self-hosting but decided it’s just too much of a hassle to get decent spam filtering and security set up.

My 2 cents. Use your own domain. It’s really cheap and now you own your email address and can move it to another provider whenever you like.

Setting it up in Fastmail is super easy if your halfway computer literate. It literally says what DNS records you need to creat.

Importing your Gmail emails is even easier: log into Gmail from within the Fastmail options. Grant access. Now it’ll import all your mail in the background.
