Writers can add a custom domain to their list. After adding, the list will be accessible via the custom domain.
- You must own the domain name you want to add.
- You must be able to modify the DNS records of the domain name.
- The domain name must be a subdomain, such as
letters.example.com. Root domain, such as
example.com, is not supported.
Add a custom domain
- Go to the list settings page, scroll down to the "Domain Settings" section
- Input the domain name you want to add in the "Your Domain Here" field
- Copy the value of the "CNAME Record" field

- Wait for the DNS record to take effect, and then click the "Save" button on the list settings page
It may take a few hours for the DNS record to take effect. If you can't access the list via the custom domain, please wait a few hours and try again.
If you are using Cloudflare, please disable the "Proxy" option when adding the CNAME record, then turn on the "Proxy" after the domain verification is successful, and be sure to select Full mode in the TLS settings.
