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.
I can't get over how any simple design is still so stupidly hard in 2024. Hoping this is a simpler tool (without having to fork over the farm!)
