AgentMail

What is AgentMail?

AgentMail is an email inbox platform built specifically for AI agents, providing them with real email addresses and full two-way communication capabilities — the same way Gmail works for humans, but designed for programmatic, agent-driven workflows. With a single API call, developers can spin up inboxes in milliseconds, no domain verification or manual setup required. AgentMail handles deliverability, spam prevention, threading, and real-time event delivery via webhooks and websockets, allowing agents to send, receive, reply, search, and organize emails entirely autonomously. Backed by Y Combinator and having raised $6M in seed funding, AgentMail is trusted by enterprises provisioning tens of thousands of agent inboxes at scale.

Key Features

• Instant Inbox Creation

  Spin up a dedicated email inbox for any agent with a single API call — no domain verification, no waiting, no manual configuration.

• Full Two-Way Communication

  Agents can send, receive, reply, forward, and maintain threaded conversations, enabling genuine back-and-forth email interactions rather than one-way notifications.

• Real-Time Event Delivery

  Webhooks and websockets push incoming email events to agents instantly, so no message is missed and response latency stays minimal.

• Semantic Search & Inbox Organization

  Agents can search their inbox contextually, apply labels, manage drafts, and filter messages — keeping conversations structured and retrievable.

• Enterprise-Grade Deliverability

  Built-in DKIM, SPF, DMARC, dedicated IPs, and spam prevention ensure emails land in inboxes, not spam folders, even at high sending volume.

• Flexible Tiered Pricing

  Plans range from a free tier (3 inboxes, 3,000 emails/month) to Startup and Enterprise levels with custom domains, white-labeling, BYO cloud, and SOC 2 compliance.

Use Cases

• Automated Customer Support : Deploy support agents with dedicated inboxes that receive customer inquiries, retrieve account context, and reply within seconds — around the clock.
• Service Authentication & Verification : Agents autonomously register for external services, receive verification codes, extract OTPs, and complete authentication flows without human intervention.
• Browser & Web Automation : Agents handling web automation tasks use their own email identities for sign-ups, form submissions, and account management across platforms.
• Agent-to-Agent Communication : Multi-agent systems can route tasks and share information between agents via email threads, enabling structured coordination across workflows.
• Invoice & Document Processing : Agents receive emailed invoices or documents, parse attachments, and trigger downstream actions like data entry or approval routing automatically.
