The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
I have used the product for over a year and although the product is sound and useful, support keeps making "improvements" without regard to past time and effort. Most recently they "upgraded" the editor but made all of our previous work wasted as we cannot use previous newsletters as templates or copies to work from, wasting all of our previous edits and content. Not happy.
mailchimp is far better.
server errors all the time
Really easy and convenient. But very less templates to choose from and restricted customization options.
