"Our phones started to ring off the hook!"

"Over the years, we've grown our customer base into the 1,000s. We had been sending email newsletters on a regular basis with limited results. We wanted to try something different. It was easy to get set up with Sigma Voice. Within a few minutes of starting our automated calling campaign, our phones started to ring off the hook! Our inside sales team booked more appointments than I thought possible. Now we're using Sigma Voice on a regular basis in addition to our email newsletter. There were a handful of customers that requested to be removed from our calling list. So Sigma Voice automatically added those phone numbers to our do not call list so they'll never be called again. Overall this has been a huge success!"
