If you want to give your Substack publication a more personalized touch, using a custom domain is an excellent option. In this guide, we'll walk you through the steps to link your own domain to your Substack publication. Please note that Substack charges a one-time $50 USD fee for this service, and you must be the publication's owner or group administrator to connect a custom domain.
- Begin by logging in to your Substack account.
- Navigate to your publication's Settings page.
- In the left navigation bar, select "Domain."
- Click on the "Add custom domain" button to get started.
- Enter your custom domain in the provided field.
- Substack will generate the correct CNAME alias you need to add in your DNS provider.
To link your domain successfully, you'll need to make changes in your DNS provider's settings. Below, you can find links to support pages for popular providers on how to add CNAME records:
- Google Domains: Create a CNAME record
- GoDaddy: Add a CNAME record
- Namecheap: How to create a CNAME record
- Domain.com: How to update a CNAME
- DreamHost: Adding a CNAME
- Bluehost: What is a CNAME?
- Hover: Managing DNS records
- Dynadot: How do I create a CNAME?
- Cloudflare: If you use Cloudflare, ensure that the “Proxy status” on your CNAME record is set to “DNS only.” The orange cloud icon should be grey, not orange.
To manually check if your configuration is ready, use the “check status” button in the Custom domain section on your Settings page.
How Long Does It Take?
After linking your custom domain to Substack, it may take up to 36 hours to fully configure. If it takes longer, check that your domain begins with "www" in your configuration settings. If needed, you can delete the configuration and start over without incurring additional charges.
Still Not Working?
If your domain is not functioning correctly, please contact Substack Support Team with a screenshot of your full CNAME record list from your DNS account, and they will assist you in resolving the issue.
You may be asked to configure a TTL by your provider; feel free to leave it as-is.
