  3. Enter the custom domain you’d like to use.
  4. Click Add domain.
Part 2: Point your DNS provider to Smile
  1. Log in to your DNS provider (e.g., GoDaddy, Bluehost, etc.).
  2. Create a CNAME or ALIAS record that points your custom domain to refs.smile.io.
Part 3: Verify domain connection in Smile
  1. From Smile Admin, navigate again to Program > Referrals.
  2. In the Custom referral domain section, click Refresh status.
  3. Confirm that the domain has been successfully connected—a green checkmark ✅ will appear if successful.
