We've had success with our campaigns, reaching customers that we would not have reached otherwise! The customer service is outstanding as well - they are always quick to respond when I need help or answer my questions along throughout this process of building out new lists for us!! There's nothing so far about them from what i can see online (that isn't positive) but if you're looking at several options try comparing each other first before deciding which one will work best/fit your needs etc.. Our goals were simple; grow revenue through targeted marketing while maintaining high levels client satisfaction via excellent follow-through after sales support once an account was established.- And it does just those things very effectively too.
