Yes, you can thank a listener by replying to their message on the Gratitude Wall. You can reply from your Teacher Dashboard on the Donations tab sorted by All, Awaiting, or Replied. Once you have replied, they will be notified within the app. Any donation without a note is marked as private by default, which means you can send them a thank you note but it won’t appear on the Gratitude Wall on the app.
