What is AgentMail?
AgentMail is the email inbox API built specifically for AI agents, giving them their own real email addresses—just like humans have Gmail or Outlook. Instead of forcing developers to hack together fragile email solutions, AgentMail provides a reliable, scalable way for autonomous agents to send, receive, reply to, and manage emails through simple API calls.
Whether your AI agent needs to sign up for websites, handle customer support, or extract data from invoices, AgentMail handles all the complex parts: deliverability, spam filtering, threading, and real-time message delivery. With instant inboxes, custom domains, and enterprise-grade infrastructure, it’s designed so your agents never miss a message—and you never have to worry about email again.
What are the features of AgentMail?
- Real Email Inboxes via API: Create fully functional email addresses (e.g., [email protected]) in milliseconds with one API call—no domain setup or verification needed.
- Two-Way Email Conversations: Unlike traditional email services that only send notifications, AgentMail supports full thread-aware replies, making AI interactions feel human-like.
- Realtime Message Events: Get instant webhooks when new emails arrive, so your agents react immediately—perfect for time-sensitive tasks like 2FA code extraction.
- Semantic Search & Data Extraction: Search inbox content intelligently and automatically parse key info from messages or attachments (like OTPs, dates, or invoice totals).
- Custom Domains: Use your own domain (e.g., @yourcompany.ai) for branded, professional agent identities.
- Attachment Support: Receive and process files like PDFs, images, and documents directly through the API.
- Developer-First SDKs: Official libraries for Python, TypeScript, and CLI tools make integration fast and type-safe.
