Launched this week
AgentMail gives every AI agent its own email inbox. Your agent sends, receives, threads, and replies to emails on its own. No shared mailboxes, no OAuth per inbox, no human in the loop. Real-time webhooks and websockets. Semantic search across inboxes. Built-in email parsing and attachment extraction. Developers, startups, and enterprises are already deploying email agents with AgentMail. Free to start.
Not trying to be an a-hole, but couldn't you just build this on top of Cloudflare email workers + SES in a weekend?
What's the actual hard part here that justifies paying for it?
AgentMail
@raymond_1907 You could build something that exchanges emails, yes. But, we provide webhooks, inboxes, threads, attachments, replies, and even custom domains. This functionality is a lot closer to what consumer mail providers like GMail and Outlook have to offer BUT for your agent.

Ok this is actually solving a problem we hit last month. We tried giving our AI agents email capabilities through Gmail API and it was a nightmare — OAuth per inbox, rate limits, the whole thing. The websocket approach for 2FA is really clever. Quick q: do you support custom domains so agents can send from @company.com?
AgentMail
@pierre_de_la_grand_rive Yeah you can connect your own domain so agents send from @yourcompany.com. You add a couple DNS records from our console, CNAME for DKIM, SPF include, MX record and we handle key rotation and deliverability from there. Glad you found us! Please reach out if you need any help : )
Also check out the special offers we have running for the launch!

This is super clean, giving each agent its own inbox makes a lot of sense.
Quick question though, what happens if an agent gets compromised or starts acting weird? How do you stop it from sending spam or leaking data?
AgentMail
@dong_recost Good question! Each inbox is isolated so one agent acting up doesn't affect others. We have rate limiting, reputation monitoring, and allow/blocklists you can configure per inbox. You can also revoke an agent's inbox instantly if something goes wrong. The isolation is actually one of the big advantages over shared mailboxes where one compromised agent could mess things up for everyone.

That is cool. Is it for the mass mailers or personal automation? How is it different from gog that I use for agents?
AgentMail
@visualpharm It is for everything. We see it as the email API of your agents' dreams. gmail, and other email providers built for humans, are not the best setup for agents considering their setup has always been anti-bot. We built to bridge that gap in the market.
Congrats on the launch! 🎉
AgentMail solves a problem I hit head-on while building my open source project Praktor — a personal AI agent assistant that runs multiple Claude-powered agents in isolated Docker containers. I needed a way for agents to send and receive email autonomously, without the nightmare of managing OAuth tokens per agent or sharing a single mailbox across them.
AgentMail was a perfect fit. The WebSocket integration for real-time message.received events made it straightforward to wire up — my gateway maintains a persistent WS connection and dispatches incoming emails to the right agent based on their inbox ID. Each agent gets its own dedicated inbox, fully isolated, which aligns perfectly with the sandboxed container model.
The developer experience is really clean. No per-inbox OAuth, the API is simple and well-documented, and the real-time delivery via WebSockets just works. Took me an afternoon to integrate, and it's been reliable since.
If you're building anything with autonomous agents that need email capabilities, this is the infrastructure you want so you can focus on the agent logic instead of fighting email protocols.

@zen_guerrilla This is amazing to hear. Thank you so much for sharing, Manolis. Appreciate the support.
Email inboxes for agents — this is the right abstraction. Tax compliance has a huge email workflow: IRS notices, broker 1099 forms arriving by mail, client communication for CPAs. An agent that can receive a 1099-DA PDF via email, extract the data, and reconcile it against on-chain records would save CPAs hours per client during tax season.
How does agent self-signup work?
AgentMail
@anmolcs We actually launched agent.email for this. This is a LP that agents can use to sign up for AgentMail - no human needed :)
Check it out and let me know if you have any thoughts!
