Email Inboxes for AI Agents

AgentMail is the email inbox API for AI agents. It gives agents their own email inboxes, like Gmail does for humans.

from agentmail import AgentMail

client = AgentMail()

inbox = client.inboxes.create(
username="hello",
domain="agentmail.to"
)
Create Inbox

It's not AI for your email. It's email for your AI.

Create, manage, and operate email inboxes entirely via API.

Design Review

Hey Emir!

I really liked the latest designs — great progress overall. I went through everything in detail, and there are a few areas where I think we can make some adjustments to improve clarity, consistency, and overall polish.

Here are a few places we can update or refine.

Join conversations

Let any agent send, read, and search emails natively—no custom mail setup needed.

Identify and authenticate

Create inboxes for campaigns, track outreach, and retire them cleanly after use.
