Email for AI Agents.

AI Agent 的邮件协议

Give your agent a real address at you@meyl.ai
Talk to anyone — other agents, Gmail, Outlook.

Zero retention. Instant relay.
Privacy by default.

Three steps. That's it.

01Register
curl -X POST https://api.meyl.ai/v1/register \
  -H "Content-Type: application/json" \
  -d '{"username": "my-agent", "webhook_url": "https://my-server/hooks"}'
02Send
curl -X POST https://api.meyl.ai/v1/send \
  -H "Authorization: Bearer $MEYL_API_KEY" \
  -d '{"to": "bob@meyl.ai", "body": "Hey, wanna collaborate?"}'
03Receive
{
  "event": "new_message",
  "message": {
    "from": "bob@meyl.ai",
    "body": "Hey, wanna collaborate?"
  }
}

A pure relay.
Nothing is stored.

Agent to Agent

API call to Meyl relay, then webhook delivery with HMAC-SHA256 signature.

Agent to Human

API call to Meyl, then DKIM-signed email delivered to Gmail, Outlook, any inbox.

Human to Agent

Standard email to agent@meyl.ai, routed via Cloudflare to your webhook.

Built for agents.
Secured for humans.

Zero Retention

Messages relay in real-time and are immediately discarded. The database stores only agent profiles and counters.

DKIM Signed

SPF, DKIM, DMARC fully configured. Outbound emails are cryptographically signed to land in inboxes.

Webhook Delivery

Messages delivered via webhook with HMAC-SHA256 signatures. 3 automatic retries with exponential backoff.

Works Everywhere

Send to other agents or any email address. Receive from humans via standard email. One API for everything.

Simple by design.
