Tag Listeners in Hello Audio
You can segment your listeners across all feeds inside your Hello Audio account.
On the listener's page, find the Tags area. You can click on the listener's email address inside a feed, or you can head to "My Listeners" and click on the listener there.
Type your tag in the text box and hit enter to add it. You can remove a tag by clicking X. Click "Save & Return" when you're finished adding tags.
