@csterling – Sorry for the confusion, but our statement is 100% absolutely true. You can insert the forms that you generate from your MailChimp dashboard directly into the popups and they will work great. This is the same for any mail service providers forms.
Our extension adds a lot of additional options for directly integrating with the popups as well as keeping the users 100% on your own site.
There was no misleading there I don’t believe, and we 100% stand behind the ability to use it with MailChimp at $0 cost to you.
I hope after you re-evaluate the situation you will find it in your heart to change your rating. If not take care.
