Give your AI agents an identity through email
49 followers
Your agents sign up for tools, receive verification codes and reply to customers, mostly from your Gmail or a shared sending pool where one bad actor gets everyone flagged. OpenMail gives every AI agent its own inbox on your domain with its own sending reputation, for one API call each. Incoming mail reaches your code over webhook or WebSocket, attachments arrive as text, and there's a hosted MCP server and a Hermes plugin. Built and hosted in the EU, free for 3 inboxes.

Hi Product Hunt, Jokūbas here, co-founder of OpenMail with @efemeralizacija .
We started in March because every agent we saw was using a borrowed email address. It signed up for tools and answered customers from someone's Gmail, or from a shared sending domain where one bad tenant got everyone's mail flagged. That falls apart once you run more than a few agents, and faster when the agents belong to your customers.
OpenMail gives each agent its own inbox: a real address on your domain, inbound delivered to your code over webhook or WebSocket, attachments turned into text your model can read, and a sending reputation that belongs to that inbox alone, so one agent misbehaving doesn't take the others down with it. There's a hosted MCP server and a Hermes Agent plugin, and all of it runs in the EU.
Most of this year went into receiving and keeping tenants apart: isolation and abuse containment, the part that never makes it into a demo video and that you need by your second customer.
Launch-day offer: make an account today and enter Launch2026 in billing before Friday 6 November for three months of Pro. The free tier is 3 inboxes and 3,000 emails a month either way.
If you've built something that needs email, tell me what broke with your current setup; that is what we build next.
And ask the hard questions about deliverability, abuse and pricing. Armandas and I are here all day and will answer every one, with numbers where we have them.
Docs: docs.openmail.sh. Thanks for having a look.
@jokubas_vaiciulis_ @efemeralizacija This could become an important part of the AI agent ecosystem. How do you handle identity verification for agents ?
Love it, where do you think differentiation will come from in this space? What’s next?
Inbound retries seem worth making very visible when an agent is on the other end. I'd want it to recognize the same message arriving twice before it sends two replies.
a sending reputation per inbox instead of a shared pool is the part i care about, one noisy agent dragging down evrything else is exactly what goes wrong with shared sending
when someone spins up a brand new inbox on a fresh domain, do you ramp its volume slowly on your side??? or is warming it up left to the customer???
@thamibenjelloun hey Thami, thanks for the question!
We ramp up a new account's sending slowly to maintain good deliverability.
Congrats on the launch! The year you spent on isolation and abuse containment probably won’t show up in a demo, but it’s what will make teams trust this in production. Good luck today.
