MySigMail Card

An open source html email template builder with drag & drop editor

Motivation

We live in an era of increasing vendor lock-in and centralized control. We have seen instances where entire regions are cut off from services due to geopolitical reasons, leaving developers and users stranded. Software should be accessible and reliable, regardless of borders.

Driven by a passion for open source, I want to provide a truly independent alternative. I am releasing the core of my commercial project, MySigMail Card, to the community to ensure that everyone has access to a powerful, self-hosted email builder.

Features

Visual drag-and-drop editor
Component catalog with ready-to-use blocks: Menu, Header, Content, Feature, Call to Action, E-Commerce, Footer
Spot editing with a component tree (Block -> Row -> Cell -> Atom)
Atom types: text, button, divider, image, menu
JSON export/import from the UI
Import modes: replace and append
Template validation + sanitization on import
Auto-persist to localStorage and hydration on reload
Preview rendered in Shadow DOM to isolate editor styles
