How do I require new subscribers to confirm their email on Substack?

Substack offers a double opt-in email confirmation option for publishers looking to get reader data collection consents. To turn it on for your publication, follow these steps: 

1. Sign into your Substack account and click on the "Dashboard" button in the top right corner. 

2. Select Settings in the navigation bar– this is your publication's settings page.

3. Select Publication Details in the anchor bar on the left side.

4. Select the toggle next to "Double opt-in for email signups".

Things to note:

  • Requiring new subscribers to confirm their email address will reduce the number of readers who receive emails.
  • If your Substack publication is in private mode, you will need see the double opt-in setting.

5. Once selected, all new subscribers to your publication will need to confirm their email address to start receiving your email newsletters.
