I want to save my theme…
While you can upload your own theme, you can't save your theme from within the visual editor.
The logic in MailPoet is to first design a draft newsletter and duplicate it to reuse its design, like this:
Your previous choice of fonts, colors, social bookmarks and content will be the same.
In the future, you'll be able to save your theme
We know how useful a Save button would be. Rest assured that this is on our to do list.
