Add users to GetResponse campaigns, with or without Paid Memberships Pro. Features Automatically add users to GetResponse campaigns when their membership level changes. Works with or without Paid Memberships Pro installed. How it Works After installing PMPro GetResponse, a new page under Settings will be added in the WordPress dashboard titled “PMPro GetResponse”. On this page, you will be prompted to enter your GetResponse API key. Once entered, you will be able to select which campaigns you would like your users to be subscribed to. If PMPro is installed, you will be able to select a different set of campaigns for each membership level you have created. If PMPro is not installed, you will only be able to select one set of campaigns for all users.
