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.
Open the domain flow
Section titled “Open the domain 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.
Enter your subdomain
Section titled “Enter your subdomain”- 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. - Click Next: DNS instructions →.
Add the CNAME record
Section titled “Add the CNAME record”The add-on shows you the exact CNAME record to add:
| Type | Name | Value |
|---|---|---|
| CNAME | go (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.
Verify the connection
Section titled “Verify the connection”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.
