AgentMail

AgentMail provides programmable email inboxes for AI agents, so agents can send, receive, and thread email through an API.

What it does

Key features to help you decide whether this provider fits your needs.

  • Manage agent inboxes through a REST API.
  • Receive, send and search messages instead of only sending outbound notifications.
  • Compare a free starting tier, fixed self-service tiers and custom enterprise options.

Check before you buyInbox count, email volume and custom domains affect cost; usage beyond an included allowance may incur charges. This is an email API, separate from Heap’s physical and virtual mailing-address directory.
