I migrated from Gmail to Fastmail a couple years ago and I have been happy with it. Migrating existing emails from Gmail into Fastmail was easy, as was setting up forwarding from Gmail to Fastmail for all future emails. The hardest part was just updating accounts across the web to use the new email. Since I'm using a custom domain with Fastmail, I can change account emails to things like foo.com@mydomain.com or bar.net@mydomain.com.
It's also easy to configure a Fastmail account to fetch messages from a Gmail inbox and even send messages via Gmail, for a seamless transition while updating accounts.
Wow, that's a neat feature. I've seen a lot of Fastmail recommendations on HN but none that mentioned this feature. Thanks for bringing it up. I'm probably far from the only person around these parts that wants to migrate off of Gmail but just hasn't made it a priority yet, and this tip certainly helps.
