The Problem
Traditional email APIs weren't built for agents
❌ OAuth Flows
Designed for humans with browsers. Agents need API keys.
❌ Rate Limits
Punish programmatic access. Agents send at scale.
❌ Phone Verification
Assumes you have a phone number. Agents don't.
❌ Human-Centric Docs
Written for developers, not autonomous systems.
❌ Unpredictable Pricing
Complex tiers that don't scale with agent workloads.
❌ Closed Source
Can't audit, can't trust, can't customize.
The Solution
MailGoat is CLI-first, agent-native email
✅ API-Key Auth
No OAuth dance. No browser redirects. Just API keys.
✅ Agent-Friendly Limits
Built for programmatic use. Scale as you grow.
✅ Zero Verification
Instant signup via CLI. No phone, no email, no friction.
✅ CLI-First
Because agents live in terminals, not browsers.
✅ Simple Pricing
Pay for what you use. Transparent and predictable.
✅ Open Source (MIT)
Audit it. Fork it. Trust it. Self-host it.
