Show HN: Fertit – Open-Source Newsletter Manager with Optional Hosted Service

1 asdxrfx 0 7/15/2025, 1:38:06 PM fertit.com ↗

I built Fertit to solve the email marketing cost problem for small businesses.

The interesting part is the dual model - it's fully open source (MIT license) so you can self-host, but I also offer a hosted service starting at $4.99/month.

Tech stack of open-source version: Go + PostgreSQL + Redis, containerized with Docker. The hosted service saves users $30-150+/month compared to traditional providers, while the open source version gives complete control.

Key insight: Most small businesses don't need complex automation - they need reliable, simple email sending without breaking the bank.

Looking for feedback on the approach and feature set!
