Agent Mail 📧

Email infrastructure for AI agents with Solana Pay integration.

Live: https://agent-mail.xyz
Version: 0.7.0
Hackathon: Colosseum Agent Hackathon

What's New in v0.7

• GET /api/stats - Public metrics dashboard (agents, payments, uptime)
• Email templates for common flows
• Improved webhook reliability

Why Agent Mail?

AI agents need email for:

• Receiving verification codes
• Platform registrations
• Communication with humans/services

But getting email is hard:

• Temp mail gets blocked everywhere
• Real providers need phone/ID verification
• No API-first solutions exist

Agent Mail solves this.

Features

• ✅ Create mailbox - unique email address per agent
• ✅ Receive emails - fetch via API
• ✅ Send emails - outbound support (rate limited)
• ✅ Webhooks - get notified on new emails
• ✅ Code extraction - auto-extract verification codes
• ✅ Solana Pay - pay with USDC on Solana
