Custom domains

Serve your short links from your own domain — go.yourstore.com/abc1234 instead of go.zerglo.com/abc1234. Available on the Growth plan.

Setup

  1. In the app, open Settings → Custom domain and enter a subdomain you control, like go.yourstore.com.
  2. Add one DNS record wherever that domain is managed:
Type    Name    Target
CNAME   go      customers.zerglo.com
  1. Back in the app, click Check status. DNS changes usually take effect within a few minutes; the TLS certificate is issued and renewed automatically — there's nothing to upload or rotate.

Once the status shows Active, every short link in your dashboard, QR code, and copy button switches to your domain.

Good to know

  • Subdomains only. Apex domains (yourstore.com with no prefix) need CNAME flattening that many DNS providers don't support — use a subdomain like go. or links..
  • Your links are yours alone. A custom domain only ever resolves your own short codes — codes belonging to other merchants return a not-found page on your domain.
  • Old links keep working. go.zerglo.com URLs you've already shared continue to redirect exactly as before; printed QR codes don't break.
  • One domain per store at the moment.
  • Removing the domain stops links served on it (your go.zerglo.com URLs are unaffected). Remove the CNAME record afterwards to keep your DNS tidy.

Troubleshooting

  • Stuck on "Waiting for DNS" — confirm the CNAME's name is just the subdomain label (go, not go.yourstore.com) and the target is exactly customers.zerglo.com. If your DNS provider proxies records (orange cloud), that's fine.
  • Status shows Failed — remove the domain and add it again; if it keeps failing, contact support.
