As a marketer, you want to send emails that are engaging and personalized for your customers. Sometimes, you may need to modify the HTML or add custom HTML code to achieve specific design features and layout options. However, editing the HTML or importing custom HTML code can cause rendering issues and display differences across various email clients and devices. To help you deal with these issues, the Customer Insights - Journeys email editor includes enhanced HTML controls that allow you to edit emails in real-time and protect your custom code from post-processing.

This feature lets you:

  • Code in HTML and see the changes right away in the email.
  • Import HTML code into the email editor as a custom section.
