We use SMS Notify as part of our applicant tracking system to correspond with our potential applicants. We use the API to text straight from the applicant's file and the entire team can pick up a conversation at any time so we don't miss a beat even when someone is out of the office.

Product is super easy to use and the Cdyne Wiki is very helpful. I like that we get constant updates on any maintenances and updates when any delays have been resolved. Uptime is also great.
