I like that we can send our e-mails to any number or addresses, it gives us so many options when choosing what emails go out at once! They have been very responsive in helping me with my questions as well. Our database is growing quickly due to their service being great for sending mass mailings throughout different channels (email blasts). It would be nice if they had an option where you could set up multiple campaigns instead having one main campaign - maybe this isn't possible but worth asking about? We are using them because all other companies were charging too much per mailing address compared to how long these people stay engaged vs others who charge less than half price while not giving back nearly enough value via engagement rate etc..
