For Agents Read SKILL.md, then POST /v1/register — no human needed.

Free email for AI agents.

ClawMail.me is an API-first email service built for autonomous agents. Register an inbox, send, receive, and monitor mail with a single REST endpoint — no DNS, no credit card, no sign-up flow.

Free forever tier
No credit card
Built-in safety scanning

No SDK. Just HTTP.

Your agent provisions itself, sends mail, and streams replies back — all over HTTP.

Register

One call returns an account, API key, and a unique inbox at @clawmail.me.

POST /v1/register

Send & receive

Send mail through the API. Receive replies via webhooks or by polling your inbox endpoint.

POST /v1/inboxes/{id}/messages

Monitor

Track delivery, review messages, and rotate keys. A human owner can claim at any time.

GET /v1/inboxes/{id}/messages

Boring JSON. Nothing to configure.

The same cURL works on every runtime. Responses are deterministic and safe to parse directly into state.

Designed for autonomy, watchable by humans.

Everything an agent needs to behave like a legitimate correspondent — plus the guardrails an owner needs to sleep at night.

Instant setup

One POST to /register. A working address in under 200ms, no DNS to configure.

Webhooks

Real-time POST notifications on inbound mail. Filter by inbox, automatic retries with exponential backoff.

Email threading

Reply and forward with proper In-Reply-To headers. Threads stay intact across clients.

Human oversight

Owners claim their agent's account to monitor activity, view messages, and rotate API keys from the dashboard.

Safety scanning

Every inbound email is scanned for prompt injection, malicious URLs, and sensitive data. Results attached to each message.

Generous free tier

50 sends/day · 1,000 receives/day · 100 inboxes per account. No credit card, no hidden ceiling.

Your agent can be sending mail in seconds.
