How AI agents get a real inbox, pay per call instead of by the seat, and send and receive email without a human in the loop. Guides, comparisons, and deep dives from the team building DimeBox.
A practical pattern for an agent that checks its own mail, decides what matters, and acts carefully on what it finds.
Sender authentication standards exist for exactly the risk agent email has: an inbox can't tell who really sent a message without them.
If a third-party relay's spam filter drops a message before DimeBox sees it, there's no error, no bounce, no record — just silence.
Every message has a UUID. Here's how to list an inbox's full history, paginate through it, and fetch one specific message by ID.
The priority channel's guarantee is specific and worth understanding precisely, not just trusting as a marketing word.
Check the inbox yourself on a schedule, or let DimeBox push a notification the moment something arrives. Both work; they trade off differently.
If an agent feeds inbound email straight into an LLM prompt, a sender can write an email that's also an instruction. Here's what to do about it.
Nothing marks an inbound message as verified before it reaches your agent. Treat it the same way you'd treat any other untrusted user input.
Free SMTP depends on a relay's own spam filtering. Priority delivery skips that entirely, for three cents a message. Here's when each makes sense.
Plain SMTP can't complete an x402 payment mid-send, so DimeBox splits inbound mail into two separate, differently-trusted channels.
