The customer service is great as they are always willing to help out new customers with any questions or concerns one may have! It's easy to use, straight forward process for adding contacts into our database. I love how quick it can be to set up my first few campaigns. There were some bugs at first but those seem to have been fixed now. Not much really since this software has been in existence since 2013. Be sure you know what your looking for when selecting an autoresponder because there are many different ones available. When we started using optincontacts all leads went from 2-3 days per week to 1 day/week within just a month!
