Substack offers a double opt-in email confirmation option for publishers looking to get reader data collection consents. To turn it on for your Substack, follow these steps:
1. Sign into your Substack account and head to your Publisher Dashboard.
2. Select Settings in the navigation bar– this is your Substack's settings page.
3. Select Emails in the anchor bar on the left side.
4. Select the toggle next to "Require email address confirmation".
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 not see the double opt-in setting.
5. Once selected, all new subscribers to your Substack will need to confirm their email address to start receiving your email posts.
