Email for AI agents
Your agents need email. To sign up for GitHub, to receive verification codes, to communicate with people on their own behalf. You don't want to give them yours. You don't want to buy a domain for each one.
AgentMail gives every agent its own @theagentmail.net address. Not for newsletters or mass email. For agents that act as individuals in the world, and need a real mailbox to do it.
The problem
AI agents are becoming actors in the world. They sign up for services, file issues, book meetings, respond to customers. They operate as individuals, not as broadcast channels. And most of what they do requires email.
Your options today are bad. Give the agent your personal email and lose control of your inbox. Buy a domain per agent and deal with DNS, DKIM, SPF, deliverability. Use a disposable email service and get blocked by every provider that checks reputation.
AgentMail is a shared domain with reputation management built in. One API call to create an address. Karma keeps the domain clean. Your agent gets a real, trusted mailbox it can use as its own.
How it works
Create an account, send and receive email, set up webhooks for real-time notifications. Everything via REST API or TypeScript SDK.
Create an account
One API call gives your agent a real @theagentmail.net address.
Send and receive
Send email via API. Receive via polling or webhooks. Full attachment support.
Stay sustainable
Karma rewards genuine conversations. Agents with healthy reply rates sustain themselves indefinitely.
Karma solves spam
Everyone shares one domain. If someone uses it for mass email, the domain reputation tanks and everyone's mail lands in junk. So we need a way to prevent that without manually reviewing every message.
Karma is a simple credit system. Sending costs karma. Receiving earns it back. An agent that sends emails people actually reply to sustains itself. One that blasts into the void runs out and gets blocked. This naturally selects for agents that behave like real people having real conversations, not like marketing tools.
Karma is only awarded for replies from trusted email providers (Gmail, Outlook, Yahoo, iCloud, ProtonMail, etc.). Emails from throwaway domains don't count. And you only earn karma once per sender until your agent replies back. No gaming the system by having someone send you 100 emails.
You start with 100 karma when you pay. That's 100 sends, or 10 accounts, or some mix. Delete an account and get the karma back. An agent with a healthy reply rate sustains itself indefinitely.
Purchase karma credits
Someone replies from a trusted domain (once per sender until you reply back)
Delete an email address (partial karma refund)
Your agent sends an email
Create a new email address
When karma hits zero, sends and account creation are blocked until you buy more or earn it back through genuine conversations.
