Your agents sign up for tools, receive OTPs, file issues, and talk to humans. They need email that acts like a person — not a newsletter pipe.
One API call. A real @theagentmail.net mailbox with sending, receiving, webhooks, and attachments. No domains. No DNS. No shared passwords.
curl -X POST https://api.theagentmail.net/v1/accounts \
-H "Authorization: Bearer am_live_..." \
-H "Content-Type: application/json" \
-d '{"address": "deploy-bot"}'
# → deploy-bot@theagentmail.net is liveGitHub — Your verification code: 481516
Your agent reads the OTP via API and finishes signup itself. No human in the loop.

01 — How it works
REST API or TypeScript SDK. Poll for mail or get pushed by webhooks.
01
One POST. Your agent owns a real address instantly.
curl -X POST https://api.theagentmail.net/v1/accounts \
-H "Authorization: Bearer am_live_..." \
-H "Content-Type: application/json" \
-d '{"address": "deploy-bot"}'
# → deploy-bot@theagentmail.net is live02
Outbound scanned by JEV so the domain stays trusted.
import { AgentMail } from "@agentmail/sdk";
const mail = new AgentMail(process.env.AGENTMAIL_KEY!);
const inbox = await mail.accounts.create({ address: "deploy-bot" });
await mail.messages.send(inbox.id, {
to: ["you@company.com"],
subject: "Deploy succeeded",
text: "All checks green.",
});03
Webhooks fire the moment mail lands. OTPs included.
POST /your-webhook event: email.received
{
"from": "github@github.com",
"subject": "Your verification code: 481516",
"to": ["deploy-bot@theagentmail.net"]
}02 — Why not DIY?
Your inbox —Hand an agent your Gmail and you've lost control of password resets, billing, and your identity.
A domain per agent —DNS, SPF, DKIM, warmup, deliverability firefighting — times every agent you spin up.
Disposable services —Burner domains are blocklisted everywhere that matters. OTPs never arrive.
✓ THE AGENTMAIL WAY
One shared domain with managed reputation. Every outbound message is evaluated in real time by JEV — phishing and spam blasts die before they leave the server.
Legit agent traffic — signups, notifications, human conversation — sails through. Everyone's mail keeps landing in the inbox.
