Yes — use an autoresponder with a confirmation link, or forward via webhook to your ESP.

Form action or client fetch?

Use a `+page.server.ts` action for progressive enhancement and SSR; use a client fetch when you're on `adapter-static` or want a pure SPA flow.

Does `use:enhance` work?

Yes — enhance your form, and your action can forward to FormLoom and return the result for the enhanced callback.

The code

For SSR + progressive enhancement, create a named action in `+page.server.ts` that reads the form data and forwards it to FormLoom. For SPA-style UX, use `use:enhance` or a plain client `fetch`.

Tips

Keep it to one field — email only — for the highest conversion.
Wire an autoresponder to send a welcome / double-opt-in email.

FAQ

Usually not — email-only forms convert best. Collect the name later in your welcome email if you need it.
