Self-hosted email server for your app and your AI agents
Every app ends up needing email. GoMailer is that whole layer, already built: a self-hosted email server in Go that handles the queue, sending pace, smart retries, no duplicates, one-click unsubscribe, bounces/complaints and GDPR, with a live dashboard. Works with any SMTP (Amazon SES, Brevo, Postmark) or Resend's API. Built-in MCP so Claude, ChatGPT, Gemini or Cursor can check and send campaigns. One payment, no per-email fees.
GoMailer is a self-hosted email server designed for applications and AI agents, offering features like smart retries, one-click unsubscribe, and GDPR compliance. It integrates with various SMTP services and includes a built-in management control panel for AI-driven campaign management.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
