AgentMail

What does AgentMail do?

AgentMail handles email for AI agents by exposing inbox creation, threaded conversations, and reply handling through an API. Developers can spin up inboxes, send and receive messages, and keep full thread history while using attachments, realtime events, semantic search, and data extraction to turn email into structured agent workflows. The build templates show ready-made patterns for scheduling, support, invoicing, and browser-based signup flows, so teams can move from a blank inbox to a working agent quickly. At scale, AgentMail is positioned for high-volume agent traffic: one customer quote mentions 25,000 inboxes and millions of emails, and the pricing table shows support for up to 150 inboxes and 150,000 emails per month on Startup. The site also shows SOC 2 compliance, dedicated IPs, custom domains, and enterprise options such as EU region cloud, BYO cloud deployment, and OIDC/SAML SSO. Backed by $6M in seed funding and used by teams like Combinator, Cursor, Replit, Vercel, and Slack, it is built for production email automation rather than one-way notification sending.

Why use AgentMail?

• It is built for two-way email conversations, so agents can read context and reply in-thread instead of sending one-way notifications.
• The template library shortens setup time by giving teams working agent patterns for scheduling, support, invoicing, and browser signup flows.
• Enterprise options include BYO cloud deployment and EU region cloud for teams with stricter infrastructure requirements.
• SOC 2 reporting, dedicated IPs, and custom domains support production deliverability and security reviews.
• Realtime events and semantic search make it easier to react to incoming mail and retrieve context without building the plumbing from scratch.

Who is AgentMail for?

• AI application developers who need inboxes their agents can read and reply to.
• Product teams automating support, scheduling, or approvals through email workflows.
• Platform engineers who need threaded email handling with API control and webhooks.
• Enterprise buyers who need custom domains, SSO, and deployment flexibility.

How does AgentMail work?

1. Connect your first inbox with the Inboxes API and give your agent a real address it can read and reply to from day one.
2. Set up Threads + replies so every conversation stays organized, then use Realtime events to trigger your workflow when new mail arrives.
3. Add Attachments and Data extraction to pull files and structured fields from incoming messages, reducing manual review before the agent acts.
4. Wire in SDKs + MCP or your preferred integration flow, then use Semantic search to surface the right conversation, request, or approval quickly.
5. Scale with Custom domains and deployment options like OIDC/SAML SSO, keeping the same workflow as more inboxes, agents, and teams come online.
