HTML for email is probably the hardest code to write. Even a teeny-tiny deviation from the rules will break the email in untold combination of os/desktop/mobile clients.

It's mid 2024. Almost 50 years since email was invented and 35 years since HTML was born. A 'basic-open-source-HTML-email-designer' must be a solved problem, right? We thought so too.

Sadly, that's not the case.

There are a few decent open source email designers but they carry dependencies that make them cumbersome to embed within your app. That's why we decided to open source our HTML Email Designer.

The SENDUNE email designer focuses on simplicity and ease of use. It is light-weight. It does pure HTML - no intermediate code wranglers like mjml. There is no lock-in of any kind. Save HTML output as a template and use with ANY email service provider.
