For the price, this software is a fantastic deal. I've sent thousands of messages without issue. The interface is intuitive enough, though it could use a few minor improvements in terms of organization. Customer support was responsive when I had a question about scheduling messages. My only real complaint is that occasionally a small percentage of messages fail to send, though it's a relatively small number. Overall, I'm very happy with my purchase and would recommend it to others looking for a budget-friendly bulk messaging solution.
