What is Mailing?
Mailing is an open-source tool designed for developing and sending compatible, consistent emails from any application. It integrates seamlessly into Node apps by adding an emails directory where templates are stored under source control, allowing for shared constants, images, and components. Built with MJML-React support, it ensures email templates are compatible across various email clients without manual table layout adjustments, and includes a preview server with hot reload for efficient development.
The tool is transport-agnostic, utilizing a sendMail function that renders React MJML templates to HTML and sends them via Nodemailer, supporting any transport options. It offers collaborative features like self-hosted previews on Vercel for team alignment and provides demo templates for customization. Mailing Platform upgrades include database integration for audience management and intelligent send blocking for unsubscribed users, enhancing email campaign control and user preferences.
