Not sure what else to say about this tool, really. It's very simple to setup, the support is fast and responsive, and I can automatically collect email addresses from all of my Facebook groups (side note, I use the included Automizy integration to double opt-them in, if the email isn't verified, my members don't get into the group!). This is a very important add-on for people looking to grow their email list using Facebook Groups with SMART automation. Excellent LTD app, thanks Group Collector and AppSumo!
