Show DEV: MisarMail — Self-Hosted Email Infrastructure (Transactional, Marketing, Bulk)

What I Built

MisarMail is a self-hosted email infrastructure platform for sending transactional, marketing, and bulk email — without paying SendGrid, Mailgun, or Resend.

Why I Built It

Every product I ship needs email — welcome emails, password resets, newsletters, bulk campaigns. Third-party email services add up fast. I wanted full control, zero per-email cost, and a simple API I own.

How It Works

• REST API — POST /api/v1/send with your payload, done
• SMTP relay — drop-in replacement for any SMTP config
• Bounce handling — automatic bounce and complaint processing
• Delivery tracking — opens, clicks, delivery status
• Multi-domain — send from multiple domains and identities

Tech Stack

Self-hosted on a Hetzner VPS via Coolify. Mailcow under the hood for SMTP, custom API layer on top.
