Add customers to your Get Response email lists.
Allow customers to sign up for your email newsletters by adding an opt-in checkbox to the user registration form of your Exchange store.
After uploading and activating the GetResponse Add-on, click the settings gear on the Exchange Add-ons page to configure your GetResponse Settings.
Add your GetResponse API Key and select which GetResponse list you want to add your customer subscribers.
Customize your GetResponse label (the message that displays next to the opt-in checkbox on the customer registration form) and select whether to check the GetResponse box by default.
