How to use the HTML 2.0 Advanced Mode
Advanced Mode offers high level customization for admins
Choose an HTML template from your dashboard -newsletters or signatures, then select Create Design. In the left panel, ensure Advanced Mode is enabled—if it isn’t, click Settings in the left panel and turn it on. Once Advanced Mode is active, you’ll see Structure, Block Elements, and Inline Elements available for your design.
Build designs by dragging a Structure first, then placing Block Elements inside it; use an Inline Box to add Inline Elements (text/image/button) horizontally — inline elements must live inside an Inline Box, not directly in columns.
To move entire sections, click on the space outside the canva and make sure the blue box text says "section", then a blue box will appear in the top right of that section with some tools like Move and Duplicate icons to rearrange items.
