I've been using Growbots for about three years now and they just keep getting better. Growbots is a wonderful platform for creating and measuring the quality of email templates. A/B testing subject lines, send times, lead types, etc. is incredibly easy and straightforward. Importing leads is also super simple and flexible. If one field has an error, Growbots let you fix it without going back into the spreadsheet. Customer service has been phenomenal and they really take your feedback to heart. The how-to guides are great for new users.

The focus of the prospecting data, emailing too, and analytics. It's got all the featured you could want from an outbound tool.

Responsiveness to product suggestions and the support I have received
