A Coach can enable “Feedback Reminders” that will automatically send reminders to Supporters when they don't respond to Pulse Feedback requests. Reminders are sent every other day after the Pulse Feedback request has been made (either manual or automatic requests).
To enable reminders, click edit project (the wheel at the upper right on your project page).
Scroll to the bottom of the page to the “Feedback Reminders” section. Click on the Enable Reminders box. Click on the green “Save the Project” button.
