Provide contacts more options to manage their content subscriptions.
By default, Groundhogg offers a global unsubscribe option to contacts to opt-out of all email communication.
You may not want this because you send email based on a variety of subjects and you want customers to choose which topics they receive emails about.
With this extension, you can extend the preferences center to allow contacts to opt-out or opt into specific tags which you use for segmentation or different topics. You can also allow contacts to opt-out of funnels they are active in.
