Mail Designer 365 version 1.1 is here, and with this update comes some seriously exciting new changes! You now have access to a world of design possibilities with the brand new Unsplash feature and we’ve made some major improvements to the app too.

New Features

Exciting new Unsplash integration

Boost your backgrounds with Mail Designer 365’s brand new Unsplash integration. This new feature gives you access to thousands of license-free images which you can use to take your designs to the next level. You can find Unsplash in the Backgrounds tab of the Contents menu, where you can choose from our specially curated collection of images, or search for a particular theme to perfectly fit your design. To learn more about this feature, check out this post.

Rounded corners for images

Create unique, polaroid-style images with the brand new rounded corners tool. This tool is great for breaking up harsh edges in your design and making it even more visually interesting. Try using it on your featured image for a super stylish effect. Simply click on an image and then use the slider in the sidebar to adjust the roundness.


  • Pre-flight checks: fixed an issue in the HTML size calculation
  • An issue when saving instant layout blocks has been fixed
  • Text color changes are applied more consistently
  • We have re-arranged the order of the style controls in the sidebar to be more consistent
