Using AI for support is such a dick move to your customers. I can't understand how companies don't see how disrespectful it is. I ran into that at work with Sonicwall recently, and had to contact our account rep to get my case to a human, not a clanker. It really made me feel like they don't care about solving my issues, and as a result I doubt very much if I would ever choose the company if I were given the power over that decision.
> To be clear about what this isn’t: we have not integrated AI into Fastmail. There’s no chatbot bolted onto the inbox, and your mail isn’t being piped through a model in the background. The MCP server is simply another API endpoint for you to use, if you want to, with the AI client of your choice.
> That distinction matters to us. Our long-term values include “Your data belongs to you” and “We are good stewards of your data”. The pattern we try to follow is: rather than continuously reworking our UI to follow every new trend, we give you the interfaces to use your data however it suits you. MCP continues that pattern. It’s there if you want it, and nothing changes if you don’t.

I have had no problem getting a human for customer support in a timely manner.
