I never got email routing to work. I doubt this will work in the general case.

This is a very long post just to say they're now running an SMTP server. I've been sending and receiving emails from Workers for two years; though for sending, you still need an external SMTP server like SES or Postmark.

Don't get me wrong, sending (and delivering) emails is genuinely hard. But we'll only know how good Cloudflare is at it after a couple years of real-world experience.

How awful is the reputation on those IP addresses going to be?

It's cloudflare, they type iddqd before every request.

Good luck trying to send emails during a LaLiga match I guess

Did anyone ask the poor people who unknowingly send mail to someone who feeds it to an AI surveillance company?

It would be interesting to send GDPR requests and have Cloudflare figure out all of the parties who got or use your mail.

Another email sending service without support for idempotency?
esseph 12 hours ago|
AFAIK there is no communication service or protocol on the internet designed with idempotency in mind. (That was worthwhile and adopted)

Sure, but this is not a protocol, this is an API. APIs that allow actions that cost money, potentially annoy users / effect your reputation in the eyes of email recipients, I believe, should allow the caller to supply a unique key to enforce idempotency.

Track state on your side.

It’s impossible to know whether an action completed successfully if an error occurs between sending the request and persisting the result

You also have no idea if it's been blocked or dropped before delivery unless you're using things like tracking pixels etc, right? And even then, that only works if they aren't being blocked (Proton Mail can do this, etc.)

It just seems like this is trying to force something that was never remotely designed for it.

You mentioned a 12-agent setup with IMAP that you might consider migrating into this platform. Could you tell me more about the overall goal of the project? I'm curious because this whole "email+agent" thing that the article talks about strikes me as kind of strange, and I'm curious what the non-spam use cases are.

The same people that think letting OpenClaw access their inbox is a good idea.

People wanting an AWS service but from Cloudflare instead of Amazon.
