I switched to fastmail a year ago and have never been happier. Their support also responds!
It was more of a mental "but but my decade-long history of gmail" thing, but it turned out that really was less of a big deal than I thought. I now have a nice custom domain and I forward my gmail to my fastmail, updating subscriptions every so often. Eventually gmail will receive no more mail I care about and I will remove the forwarding altogether. Its getting there!
Looking back on it now, about a year after migrating, my only regret is I didn't do it sooner.
If you aren't a FastMail customer yet, you're gonna assume we're shills. We're not, it's just the sort of quality product that makes you want to tell others. It's like having found Gmail in 2005.
No angels anywhere.
