Connect a custom domain (from the add-on)

You can connect a custom domain — so your links read go.yourcompany.com/feedback instead of go.formslug.com/feedback — directly from the FormSlug add-on. The full setup, including DNS instructions and troubleshooting, lives at Custom domain in the Workspace section; this page covers the in-add-on flow.

The add-on offers two entry points to the same flow:

  • From the success screen after creating a slug: click Connect your domain →.
  • From the home screen: click the upgrade nudge, then Connect a custom domain.
  1. In Your subdomain, type the subdomain you want — for example go.yourcompany.com. Use a subdomain rather than your root domain so your main website stays untouched.
  2. Click Next: DNS instructions →.

The add-on shows you the exact CNAME record to add:

TypeNameValue
CNAMEgo (or your chosen host)caddy.formslug.com.

In your DNS provider (Cloudflare, Google Domains, etc.), add that record and save. Some providers require a trailing dot after the value — see Custom domain for provider-specific notes.

Back in the add-on, click Verify connection. FormSlug checks DNS:

  • Verified — new links are now issued on your custom domain.
  • Pending — DNS hasn’t propagated yet. Wait a few minutes and click verify again.
  • Failed — double-check the record host and value, then re-verify.
  • The full setup guide — including troubleshooting and disconnecting a domain — is at Custom domain.
