The ability to change templates as needed, being ableto add attachments directly from your computer via ftp uploads/downloading are some of its great features! I will continue using this product due it's ease-of use & low learning curve once you have learned how easyUltra Mail can be used along with their support team who make sure they answer any questions right away!! Not much at present but only because we're just starting out so nothing major yet :) We've been provided very helpful training by our sales rep regarding setting up emails correctly (ie correct images) which saves us time not having them sent incorrectly first go around!
