Improved: Better Design Intelligence
The Preflight Check tool is your copilot for successful email design. Before you hit send, the Preflight Check will run, making sure you've covered all bases.

This update brings two useful updates to the Preflight Check to give you even more peace of mind before sending:
- Smarter Preflight for Mobile: Our Preflight Check now automatically alerts you if there are "detached" layout blocks in your mobile view. This ensures your responsive design stays perfectly aligned on every smartphone:
The Preflight Check provides a hint if you have separate mobile and desktop blocks
- Instant Image Optimization: If your email contains large images, Preflight Check now offers a direct shortcut to the image optimization tool, so you can crunch those kilobytes in one click:
Fixed: Further Improvements in this Version
As well as the new features added in this version, we’ve also been working hard under the hood to ensure Mail Designer is running smoothly:
- macOS 26 Tahoe Support: We fixed an issue where some images couldn't be imported via Drag & Drop on the newest macOS version. Drag away!
- Reliable Alt-Texts: Updates to image Alt-Texts are now saved instantly and reliably, ensuring your emails remain accessible.
- Perfect Spacing: We’ve corrected a bug that caused incorrect margins in some exported designs. Your final result will now match your editor view pixel-for-pixel.
- Team Organization: The sorting order of Team Documents now stays exactly as you left it, even after refreshing the list.
As always, this update includes general stability improvements and small bug fixes to keep your creative process as smooth as possible.
