Build engaging experiences and supporter journeys

Whether you’re looking to grow your list or engage your existing supporters, our sharing functionality and seamless integrations make it a breeze.

Your supporter data will automatically flow into the email marketing tool, including segmentation data, so you can build automated email sequences that are tailored to each individual supporter and their behaviour.

You can also use Impact Stack to create a range of engaging actions, from quizzes and surveys to event and volunteer signup forms. Through personalised redirects after actions and the overlay feature you can design smooth on-page user journeys and place multiple calls to action in one go.
