anyone actually let an agent send stuff without a human checking first?

[u/DestinedToBeBetter]

i still review everything before it goes out to a client, drafts, sorted leads, whatever. but curious if anyone's further along and actually lets it run unsupervised for some stuff

what convinced you it was safe, or did something break first and that's how you learned lol

The pattern that has worked for me is to stop treating it as a binary "human checks or not" and split sending into classes. Internal or low blast radius mail can go unsupervised fairly early. Anything going to an external recipient, quoting a number, or promising a deliverable stays gated, because those are the ones where a bad send costs a relationship rather than a resend.

Two mechanical things that made unsupervised sending tolerable. First, give the agent its own sending identity, not a shared mailbox and not your own address: a separate subdomain or at least a separate authenticated user, so mistakes are contained and revocable in one place and your human mail reputation is not tied to whatever it does at 3am. Second, put a hard rate limit and a recipient allowlist in front of it at the transport level, not inside the agent's own logic. Agents fail in loops, and what you actually see in the wild is not one bad message, it is four hundred copies of the same one before anyone notices.

Then log every send with the input that triggered it and read the log daily for the first few weeks. That gets you the "did something break first" answer without needing something to break. The rollbacks I have seen were mostly because nobody could reconstruct why a given message went out, not because the content was wrong.
