Mail Designer 365
Karlsfeld/Munich, Germany
What it is
Mail Designer 365 is a Mac email design app for creating and sending branded campaigns. Its drag-and-drop editor lets users assemble responsive newsletters from text, images, buttons, links, and layout blocks without writing code. The template gallery lists 291 newsletter templates, and the app creates a mobile-optimized version of a design with a preview. Campaign tools include scheduling, contact import, audience segmentation, and reports on opens, clicks, unsubscribes, and bounces. Contacts can be imported with a Mailchimp or Campaign Monitor API key. The API can fill design placeholders and send emails automatically, including through FileMaker workflows. Each API delivery uses 25 stamps; regular campaign delivery uses one stamp per recipient as a base. Browser participants, including Windows users, can preview and discuss drafts, but editing shared designs requires the Mac app and a plan. The free Karlsfeld plan includes 500 stamps per month and allows up to 20 designs to be stored and fully edited; designs beyond that can be viewed but not edited or saved. Mail Designer Essentials is $5 a month, and a 7-day trial is listed. The maker says users can send through their own email account, with credentials stored on the Mac and messages sent through the email provider.
