It's easy to use for our team members who are not tech savvy at all! The interface was very simple & intuitive as well so it wasn't hard getting them up-to speed with their first few emails tracked via this software. I didn’t find any downsides or dislikes about using whoreadme but would like more options in terms of how many messages can be viewed simultaneously (as opposed to just one). We were able track open rate/click through rates per mailer type which has been helpful when trying new campaigns / marketing ideas without having previous data from other sources available.
