Show HN: AIThreads – Give your AI agent an email address in 30 seconds
Hey HN,
I've been building voice AI agents for the past year, the kind that answer phone calls, book appointments, handle customer inquiries. It was going well until a client asked: "Can it also handle our email?"
Turns out, wiring an AI to a phone system is one thing. Wiring it to email is... a whole different mess. SMTP credentials, MIME parsing, threading headers (References, In-Reply-To), bounce handling, deliverability reputation. I spent two weeks on plumbing before my agent could read its first email.
That's when it hit me: every developer building AI agents is going to hit this exact wall. So I built AIThreads [1], the email infrastructure layer so you can skip the plumbing and get straight to the AI logic.
How it works:
Instant inboxes: Create support@yourorg.aithreads.io via API.
No DNS, no verification, just works. (unless you are adding your own domain)
Webhooks -> Email arrives → we POST parsed JSON to your endpoint → your agent decides what to do. Send via API -> Agent composes reply, calls our API, we deliver with proper threading so conversations stay grouped. Knowledge Base (RAG) -> Upload your docs, we embed them. Query for relevant context before generating replies. Smart escalation -> Sentiment analysis and priority detection built-in. AI knows when a frustrated customer needs a human. InBuilt Tools -> Pre-Built tools to manage the emails.
Try it now: Email hey@aithreads.io – our demo agent will reply.
