Thanks for your post! TestRail’s report email options currently would include the full HTML version in order to render the full functionality of the report properly. We use this method to provide external users the same experience as viewing the report directly within TestRail. That said, we’re happy to review adding a ‘light’ PDF version or similar in a future update to TestRail. As a workaround, you can always generate the report and use your browser’s print to PDF feature to save this as a report and email this out manually if needed. Hope this helps!
