Equinux has revved Mail Designer Pro for Mac OS X to version 2.5. It’s compatible with OS X El Capitan. The upgrade also sports a new sidebar that offers quick access to content and formatting controls.

The new paragraph style feature in Mail Designer Pro 2.5 gives you an instant control over the look and feel of your entire mail document. You can make adjustments to a style and instantly preview the changes across your entire design . You’ll even be able to see what it’ll look like on an iPhone or iPad. What’s more, version 2.5 is packed with artwork and tools for building email newsletters.

Existing Mail Designer Pro users get the new features and can update to 2.5 free-of-charge now on the Mac App Store and at the equinux website (http://tinyurl.com/o9kljsg). Mail Designer Pro 2.5 is available for US$49.99 for a limited time. Normally, it’s $89.99.
