AgentMail - The API-first email provider for AI agents
See original launch post

TLDR

AgentMail is the first email provider for AI agents. Use our API to give your agents their own email inboxes.

Why?

We started building email agents because they can live within users’s inboxes in their inboxes and authenticate themselves with third-party applications. But building on top of legacy providers such as Gmail is a struggle. They

  • Lack API support for creating new inboxes
  • Charge monthly subscriptions per inbox
  • Impose restrictive rate and sending limits
  • Offer poor developer experience

These providers don’t scale with both inbox creation or volumes of emails sent/received that AI agents often face, so we’re rebuilding email infrastructure from scratch to enable this.

Solution

AgentMail is an API-first email provider that gives agents their own inboxes to send, receive, and act upon emails. Think of it like Gmail, but with

  1. Programmatic inbox creation and management
  2. Usage-based pricing scaling with emails sent/received
  3. No restrictive rate/sending limits
  4. Real-time events over webhooks and websockets
  5. Simple API key auth – no OAuth headaches
  6. Built-in API permissions and agent guardrails
  7. Semantic search across every inbox in organization
  8. Automatic labeling with user-defined prompts
  9. Structured data extraction
  10. And more on the way!
