Why I Built AgentsMail

It started with a simple idea: let my AI agent send an email.

The Gmail Nightmare

I asked my agent to connect to Gmail. What followed was a 19-step obstacle course:

Create a Google Cloud account
Create a new project
Enable the Gmail API
Configure OAuth consent screen
Create OAuth credentials
Set up redirect URIs
Handle OAuth flow in code
Exchange authorization code for tokens
Store refresh tokens securely
Handle token refresh logic
Deal with 2FA requirements
Navigate “Less secure app access” deprecation
Generate App-specific passwords
Configure SMTP settings
Handle rate limits and quotas
Parse Gmail’s API response format
Deal with label/thread complexity
Test… get a security warning from Google
Give up.

My agent couldn’t do any of this. It doesn’t have a browser. It can’t click through OAuth consent screens. It can’t receive 2FA codes.

The Security Problem

Even if I could connect Gmail, there was a deeper issue: I didn’t want my agent reading my personal email.

My inbox has bank statements, medical records, private conversations. Giving an AI agent full access to that? No thanks.

The alternative — creating a new Gmail account just for the agent — meant going through the entire registration process again. More phone verification, more CAPTCHA, more friction.

The Realization

Email is the internet’s oldest and most universal communication protocol. Federated, asynchronous, identity built into DNS, security built into DKIM/SPF/DMARC. Every system in the world can send and receive email.

But there was no email service designed for AI agents. Every existing solution assumed a human sitting at a keyboard.

One API Call

So I built AgentsMail. The entire registration is one POST request:

curl -X POST https://agentsmail.org/api/getemailaddress \
  -H "Content-Type: application/json" \
  -d '{"agent_name": "my-agent"}'

That’s it. No OAuth. No Google Cloud console. No 2FA. Your agent gets its own email address, 10 free sends, and can start communicating immediately.

What Makes It Different

Zero friction — One API call, no sign-up needed
Agent-native — Designed for programs, not people
Free — 10 sends included, upgrade for unlimited
Encrypted — AES-256-GCM at rest
Open source — github.com/huberthe-pro/agents-mail

Try It

Install the AgentsMail skill on ClawHub, or tell your agent:

Install agentsmail.org/skill.md and register a mailbox for yourself.

Your agent will have its own email in 30 seconds.

AgentsMail is open source and free. Built with Cloudflare Workers, D1, and TypeScript. Check it out on GitHub.
