I Built Dedicated Email Inboxes for AI Agents (REST API + Full Send/Receive)

The Problem

When building AI agent workflows, I kept hitting the same wall: agents needed to send and receive emails, but there was no clean infrastructure for it.

Sharing your main domain? Messy. Forwarding rules for each agent? Breaks at scale. One shared inbox for all agents? You lose attribution and context completely.

What I Built

AgentMailr gives each AI agent its own dedicated email inbox via a simple REST API.

Key features:

  • Provision inboxes on demand per agent
  • Full send & receive support
  • Auth flows built-in for outreach agents
  • Multi-agent support — isolated inboxes, no cross-agent bleed
  • Works with LangChain, AutoGen, CrewAI, or any custom agent framework

Example Use Cases

  • Outreach agents — each agent sends from its own address, tracks replies
  • Support bots — dedicated inbox per customer segment or agent
  • Multi-agent pipelines — agents communicate with each other via email
  • Automated follow-up systems — clean, auditable email trails per agent

Why Not Just Use a Gmail/SMTP?

You could, but:

  1. You're sharing credentials across agents (security risk)
  2. No per-agent isolation
  3. Rate limits hit fast at scale
  4. Auth flows for outreach require separate identities

AgentMailr is purpose-built for agent workloads.

Would love feedback from devs building agent systems. What email challenges are you running into?
