I couldn't believe how simple the software is to use. I'm not tech savvy, but i was able to install and set up the software in about 30 minutes. The Mail Sender has so many features that keep me organized and saves time. I like that i'm able to personalize my mailing list with one click. Also, customer service is great. Any time i have a question or problem, i'm able to get an answer usually within 3-4 minutes. Great job Atomic!
