Create custom referral links

Make referral links more memorable by using subscriber names or customize by using your own domain.

🔒 This feature is available to Kit customers and users with an existing Referral Program.

By default, all SparkLoop referral links are in the format: https://sparklp.co/XNDJNFSN

We offer two options to create more memorable links.

Custom referral links

Use a custom subdomain for your links (e.g. https://join.mydomain.com/12345) to improve deliverability and make links more attractive.

⚠️ Important: The referral link must be a subdomain (e.g. join.mywebsite.com) and cannot be a root domain (mywebsite.com).

To set this up:

  1. Choose your subdomain, e.g. join.mydomain.com.

  2. Create a CNAME record with name join.mydomain.com and value refs.sl-permanent.link.

  3. Click Verify DNS to confirm the record is set up correctly.

⚠️ Note: If you're using Cloudflare, make sure NOT to proxy the CNAME through their network. It may also take a few hours for the CNAME record to propagate.

Once you've changed the referral domain, a re-sync of all your subscribers will be triggered. Read more about that here.
