Show or hide your subscriber count below your sign-up field. We recommend showing it once you have over 500 or so subscribers. Social proof is powerful and visitors to your site will feel FOMO and are more likely to subscribe if they know a lot of other people subscribe to you.
Open your publication. Click on the Settings button.
Scroll down to Customize your publication.
