Point your agent at robotomail.com/skill — it reads the page and signs up via API.
A default mailbox is created at signup — your agent has a real email address immediately.
Send with a POST. Inbound arrives via webhooks, SSE streaming, or polling.
Parse the event, generate a response, reply. Threading is automatic.
RESTful endpoints for every operation. Create mailboxes, send messages, manage threads — all through clean JSON.
Get notified the instant email arrives — via webhooks, SSE event streaming, or polling. HMAC-signed payloads with automatic retries.
Send from your own domain with auto-configured DKIM, SPF, and DMARC. Guided DNS setup with automatic verification.
Automatic thread resolution via In-Reply-To headers and subject matching. Context preserved across replies.
Upload to secure cloud storage, attach to outbound messages. Presigned download URLs for inbound.
Per-mailbox daily and monthly send limits, storage quotas, and suppression lists. Stay in control of what your agents send.
3 mailboxes included · $5/mailbox after
Unlimited inbound across all plans. No credit card required for free tier.
Those are transactional email services for humans. Robotomail gives AI agents their own mailboxes with real addresses — they can send and receive email autonomously, not just fire-and-forget.
Yes. One POST to /v1/signup creates an account and returns an API key. Point your agent at robotomail.com/skill and it can onboard itself end-to-end.
One mailbox, 50 sends per day, 1,000 sends per month, 1 GB attachment storage, and a platform email ([email protected]). No credit card required.
Yes. Add your domain, configure the DNS records we generate (MX, SPF, DKIM, DMARC), and we verify automatically. Available on the paid plan.
Three ways. Register a webhook for real-time push, connect to the SSE event stream (GET /v1/events) for real-time pull without a public URL, or poll GET /v1/mailboxes/:id/messages on your own schedule.
We auto-configure DKIM, SPF, and DMARC for every domain. Each mailbox has its own send limits and suppression list to protect your sender reputation.
Their ToS prohibit automated use by bots. You can't programmatically provision mailboxes, rate limits are restrictive, and costs scale badly. Robotomail is built for agents from the ground up — create a mailbox with one API call, no OAuth dance, no per-user seats.
Free tier includes one mailbox and 50 sends per day. No credit card required.
