How to Convert InDesign to HTML for Email?

Converting an InDesign (INDD) file to HTML for email is possible—but comes with specific challenges. Email clients have strict limitations, so designs must follow email-safe HTML rules. To simplify the process, consider starting with a pre-built email template that uses tables and inline CSS.

When exporting your design from InDesign to HTML, it's best to use inline CSS to ensure better compatibility with various email clients. For images, select "Link to Server Path" to enhance their appearance in the email.

After the export, open the HTML file in a text editor, copy the code, and paste it directly into the body of your email.
