Adding FERMÀT to a Custom Domain

Learn how you can connect your FERMÀT funnels to a custom domain as a subdomain.

Updated this week

To connect your FERMÀT funnels to a custom domain, you’ll need access to your DNS provider and the ability to configure a CNAME record.

Depending on when you onboarded with FERMÀT, a custom subdomain may have already been created for you as part of onboarding.

What's in this guide:


Choose Your Subdomain

Your FERMÀT funnels will live on a subdomain of your existing brand domain.

Make sure the subdomain you choose is not already being used elsewhere on your website or for other services.

  1. To begin setup, navigate to your FERMÀT dashboard:

  2. Go to SettingsDomains

  3. Select a subdomain for your FERMÀT Shops. This will be where your funnels are hosted.

    • Popular options include:

      • shop.yourbrand.com

      • try.yourbrand.com

      • get.yourbrand.com

Important: Once you choose a subdomain, it cannot be changed later.


Configure your DNS

To complete this step, you’ll need access to your DNS provider, typically the same platform where your domain was purchased (e.g., GoDaddy, Cloudflare, Shopify).

If you don’t have access, connect with someone on your team who does.

  • You’ll be adding a CNAME record that points your new subdomain to FERMÀT.

Add a CNAME record with the following details:

  • Type: CNAME

  • Name: your subdomain (e.g., shop, try, get)

  • Value: cname.fermat.shop

Reminder: The Name should exactly match the subdomain you selected in the previous step.

Step-by-Step Setup

  1. Log in to your DNS provider

  2. Navigate to the DNS settings

  3. Click Add record

  4. Choose CNAME as the record type

  5. For the name value use the subdomain you chose above.

  6. Enter your chosen subdomain and the target value above

  7. Click Save

  8. After your DNS record has been added, log in to your FERMÀT dashboard

  9. Add that same subdomain name to the field below.

  10. After your DNS record has been added, log in to your FERMÀT dashboard

  11. Add that same subdomain name to the field below.


Cloudfare Set Up:

  1. Log in to your Cloudflare account

  2. Navigate to the DNS tab

  3. Click Add record

  4. Use the following configuration:

    • Type: CNAME

    • Name: shop (or whatever subdomain you selected, like try, get, etc.)

    • Value: cname.fermat.shop

  5. Set Proxy status to DNS only

  6. Click Save


Once you save the subdomain should connect within 10 minutes but can take up to 24 hours. If your subdomain is still not connected after 24 hours please contact [email protected] for additional assistance.
