Design Studio: find and fix errors with the new review panel

Use the review panel to find errors that could prevent your email from sending, audit your images, validate your links, and see how you score against SpamAssassin to improve the quality of your message.

The panel features a new readiness score which flags critical errors and warnings, and highlights tips to improve common issues in email.

Previously, these tools were hidden in the code editor. Now you can access them from the same review panel in either the visual or code editors!
