I do not normally write reviews, but this one deserves five tacos. It had been on my list for a while, but I was not sure if it would be helpful. However, I recently needed to begin sending SMS, and it has gone well thus far. Although the user interface could be improved (there appear to be minor bugs in the UI), it is an essential solution for SMS management. Do not pass up this offer. Oh, and I forgot to mention how great their support team is.
