I like how easy it is to send text messages from the app. Also, how simple it is to set up your account/sender number filters (using the keywords). The only thing that would make me want to use this product even more is if the sending limit was unlimited. My clients are always confused when I try to explain to them what the limits are for each package that we offer. They want to know what they can send per month, but I don't have an easy way of showing them. So having something in writing or easily accessible would be great!
