ActiveMember360

Does ActiveMember360 work with OptimizePress?

ActiveMember360 should work fine to protect your OptimizePress created pages. We use it's sister - iMember360, in one of our businesses to integrate with Infusionsoft, and that works fine with OptimizePress, so you should be fine. 

Although OptimizeMember is great, if you're using ActiveCampaign and need a more in-depth integration, ActiveMember360 is going to be better suited as it has more advanced integration functionality

OptimizeMember is designed as a basic membership system but doesn't have in-depth integrations with those services - just a simple integration to send buyers to ActiveCampaign.  You cannot protect pages based on tags and other ActiveMember based information with OptimizeMember
