I like how easy it was to use, you don't have to be tech savvy or know anything about computers at all. The software makes everything very simple and straight forward. I love that you can send mass outbound emails with different variations so that they are sent in bulk without having to do each one individually. It's also great because we're able to track our open rate which helps us determine what works best for future campaigns. Nothing as far as I'm concerned. If there were any downsides then maybe adding more features would help but nothing comes up when using this program. We've been able to get better results than ever before by being able to send out thousands of emails with ease.
