Removing Google as a Single Point of Failure Part 2: Gmail

You could lose your GMail account, and not Lise much data if you try to get people to not use your GMail address.
If gmail goes down the mail will just remain on fastmail.
I do this for my own domain and it works fine, the only caveat is emails can be delayed by 30 minutes or so as gmail uses some heuristic method to time its POP fetches.
Its a good solution as you get gmail features like classification and auto reply hints, but you can ditch gmail at any time if google become too obnoxious.
The last TWO times I had Docker on my Desktop, some update caused it to fry itself and bring my computer to its knees trying to restart something that it had "uninstalled". I said to it the last time that if it wanted so badly to be uninstalled, that it could just stay that way.
Quite a few are still on Windows 7 - but who cares, they still work and security vulnerabilities don't matter as they are for one purpose and have limited access only to their own sandbox shared folder.
I really like fastmail and recommend it.
I like how they have wizard type things to help you setup your DNS records for SPF and DKIM - I know how to figure it out, but its nice to just cut and paste.
They also support 2FA for the admin account, and you can make a bunch of dedicated logins for each app which you can disable easily if a device is lost or compromised.
Edit: been using it for 5-6 years now. Got three 3yr plan. It has been awesome and I can configure my own deliverability settings or leave it up to fastmail. I have it so that other services will send me failure reports but I haven't had issues at all.
