Engage: Custom HTML Preview

Custom HTML Preview

JavaScript is disabled in this preview window to protect against XSS security vulnerabilities. This means that JavaScript used in visual rendering will not work.

This preview function also works with duplicated messages. When you duplicate from the message history section, you will have the ability to download and edit a message with HTML. You can also click Upload to overwrite that HTML file with a new version.
