See my comment in this thread - I got an email from "someone" (an AI clearly) that signed up for my service (togetherletters.com) from the same domain (agentmail.to) after we had launched on ProductHunt. I looked up the address and that email was never used for a signup and it was just a way to then pitch their product (second email, not the first one it sent). I hate this so much and this is going to now make email just as bad as parts of the web.
I agree with what you’re saying, but I think that email was one of the first parts the web to become terrible. This happened a long time ago, we’re just used to it.
I will say in my case, the user was too lazy to mask the from address and agentmail.to was right there. Didn't even have to dig into the headers.
This was likely a free tier user. We do this intentionally and don't allow free users to send from custom domains, so you can have a easier time identifying LLM emails. In this case, it seemed like it worked :)
And for paid users the receivers don’t need to have an easier time identifying the LLM email? What kind of reasoning is that?
To be the advocate of the devil here:
A lot of people believe that spam issue would be largely solved if each email costed 0.001$
I got one from IssuePay, which seemed 100% automated. Didn't seem like something that should be automated either.
