AI Agent Email Verification & Self-Onboarding

One API call. The agent calls LobsterMail.create() to get an account, then createInbox() to get an address. No human signup, no OAuth, no API keys to copy-paste. The agent does it all.

No. The agent creates its own account and gets a bearer token automatically. The token is persisted locally so subsequent calls just work. Zero human configuration.

Yes. The agent calls waitForEmail() with a filter for the expected sender, extracts the verification code from the email body, and submits it. The whole flow is a few lines of code.

waitForEmail() accepts a timeout parameter. If the email doesn't arrive before the timeout, the promise rejects and your agent can retry or take a different action. You control the retry logic.

Under a second. The createInbox() call returns immediately with a real email address. The agent can start receiving email right away.

That's the whole point. The agent gets its own address, uses it to sign up for Stripe, GitHub, Slack, or anything else that requires email verification. It handles the verification flow end to end.

Yes. Every inbox gets its own address. You can create multiple inboxes per agent too — one for each service it signs up for, if you want that level of isolation.

Any framework that can call a TypeScript/JavaScript SDK. OpenClaw, LangChain, CrewAI, AutoGen, Mastra — all work. LobsterMail also ships as an MCP server for Claude Desktop, Cursor, and Windsurf.

On the free tier, inboxes expire after 30 days of inactivity. On paid plans, inboxes are permanent. Either way, the agent can create a new one anytime.

Yes. An agent can create as many inboxes as its plan allows — 5 on free, up to 300 on Scale. Useful when you want separate addresses for different services or workflows.

With Gmail, your agent sees your entire inbox, and one bad prompt injection could send emails as you. LobsterMail gives the agent its own isolated address. Separate credentials, separate reputation, separate risk.

Yes. Free accounts can create up to 5 inboxes and receive up to 100 emails per month. Enough to get started. Sending requires verification — either a tweet or a credit card on file.
