I like how easy it was to set up my account and use in our business. It's very intuitive and has some great features we haven't been able to find elsewhere. There really isn't anything too much i dislike about this program but maybe if you're looking at other programs or services out there, make sure they have as many of your requirements already built into their product as possible before choosing them over Mailpreparer! We've found a way to easily manage all our customer addresses and senders without having to spend time manually entering data each day. This allows us to focus more intently on what matters most - generating revenue.
