Hiya Mauticians 
Just wanted to share a plugin that’s been really useful, EasyMJML Builder, built by Sebastian Fahrenkrog and shared with the Mautic community! It’s totally free & open-source.
If you have ever found GrapeJS a bit limiting for email design, this is worth checking out. It brings a proper MJML-based editing experience into Mautic, with a cleaner interface and more reliable rendering across email clients. The best part? It works alongside GrapeJS, so your existing templates stay untouched!
We’ve put together a full overview of the plugin on our site if you want to learn more before installing:

Big kudos to Sebastian for building this and making it available to everyone. Give it a try and let him know what you think! 
Best,
Ricardo
