## What it is
Mailtrain is a self-hosted newsletter application built on Node.js and MySQL/MariaDB for managing subscriber lists and sending email campaigns. It includes list segmentation, custom fields, MJML templates, automation, and a built-in Zone-MTA for mail delivery.

## Use cases
- self-host a newsletter app instead of Mailchimp
- manage subscriber lists and send email campaigns
- send RSS-to-email automated campaigns
- segment mailing lists with custom fields
- host subscription management forms on my own domain
- send bulk email from my own server

## When to choose
- you want full control over your email marketing data on your own infrastructure
- you need subscriber list management, segmentation, and templated campaigns without SaaS fees
- you want built-in SMTP delivery via Zone-MTA with minimal setup
- you need granular multi-user permissions and hierarchical namespaces for teams

## When to avoid
- you need a fully managed service with high deliverability guarantees
- you cannot run your own server with at least 2 vCPU and 4 GB RAM
- you need advanced drag-and-drop marketing automation comparable to commercial platforms
- you lack the ability to manage DNS entries for multiple endpoints
