Migrating from Gmail to ...?

I’ve heard great things about fastmail.

For spam and potentially shady sites, I have used SpamGourmet since 2003. It’s an amazing service. Bit of a warning that some websites will not accept the domains available and that you’ll want some technical savvy know-how

I second G Suite especially for a personal email. At that point you’re no longer the product since you’re paying for the account. I love the spam filter, labels, and other filters.
