Email Inboxes for
AI Agents

AgentMailr is the email inbox API for AI agents. It gives agents their own email inboxes, like Gmail does for humans. Extract OTPs, verify links, and manage communications—entirely via API.

curl -X POST https://api.agentmailr.com/v0/inboxes \
-H "Authorization: Bearer $AGENTMAILR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"username": onboarding,
"domain": stripe.com
}'
Live Inbox

This is a real email inbox just created for you.
Send it an email and see it show up in real time.

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

[ WORKFLOW ]

Three steps. That's it.

// STEP 01

Create an inbox

Your agent gets a real email address like signup-bot@agentmailr.com in one API call.

// STEP 02

Use it anywhere

Sign up for services, receive notifications, get verification emails — just like a human would.

// STEP 03

Extract & act

OTP codes, verification links, and summaries are parsed automatically. Your agent gets structured data.
