HTML Block
- Allows users to easily drag and drop a block for the seamless insertion of custom HTML directly into the newsletter content.
- Advanced validation ensures HTML compatibility with various email clients, preventing layout disruptions by automatically identifying and restricting certain tags, like script or HTML5 media object tags.
- While allowing custom HTML, the block maintains newsletter integrity by blocking problematic HTML inputs.
- Navigate to the Letterhead section and click on Newsletters in the left panel.
- To start creating a newsletter, you have two options: select the Blank template or choose a template from the dashboard.
- To add the HTML block, simply select it from the right panel and drag it onto the desired location on the newsletter.
- The HTML block will be displayed as a placeholder in your newsletter.
- The HTML editor will be displayed on the right side of the page.
- Any changes made to the HTML block will be automatically saved.
