I've been a happy Fastmail customer for years, and one of the best things about Fastmail has been how they just incrementally make things slightly better, as if they somehow haven't learnt how to enshittify.

So on seeing this title, I was a bit worried.

> It’s worth being transparent about what that looks like at Fastmail: we haven’t integrated AI into your inbox, and your mail isn’t being processed by a model in the background. Our MCP server is simply an API endpoint available if you want to connect an AI client of your choosing with your explicit authorization, and nothing changes if you don’t.

Phew.
