How do I create a contact form in Lovable?

Describe the form fields you want in chat (name, email, message) and ask Lovable to build a contact form; it will generate the React form with validation and wire it to a submit handler.

Where do Lovable form submissions go?

Nowhere, by default — a form only exists on the front end until you connect a destination: a database table (Lovable Cloud/Supabase) and/or an outgoing email via an integration like Resend.

How do I save form submissions to a database?

Connect Lovable Cloud (or your own Supabase project), then ask Lovable to create a table for submissions and wire the form's submit handler to insert a row into it, with row-level security limiting who can read the data.

How do I email form submissions to myself?

Connect an email integration (Resend is the standard option), then ask Lovable to trigger a server-side function that emails you the form data whenever it's submitted.

Why isn't my Lovable contact form working?

Check, in order: whether a submit handler is actually wired up, whether a backend (Lovable Cloud/Supabase) is connected if you're saving data, whether client-side validation is blocking submission, and the browser console for errors.

Why aren't form emails being delivered?

Most delivery failures trace back to an unverified sending domain, spam-folder filtering, or a server function that's failing silently — check your email provider's logs (e.g. Resend's dashboard) first.

How do I validate form fields?

Describe the exact rules per field (required, format, length, matching) to Lovable and ask for both client-side validation for instant feedback and server-side validation before the data is saved.

How do I create a multi-step form?

Describe the steps and what data each collects, and ask Lovable to build a wizard-style form that keeps state across steps and only submits everything on the final step.

How do I upload files through a form?

Use Lovable Cloud's (or Supabase's) storage buckets: ask Lovable to add a file input, restrict file type and size, and upload to a storage bucket with access rules controlling who can read the file later.

How do I create an enquiry management dashboard?

Ask Lovable to build an admin-only page that lists submissions from your database table, with search, status filters and the ability to mark enquiries as handled — protected by authentication and row-level security.

How do I send automatic confirmation emails?

Ask Lovable to trigger a server-side function after a successful form submission (or sign-up) that sends a confirmation email via an integration like Resend, using a template you describe.

How do I connect Resend to Lovable?

Open the Resend integration in Lovable (or ask in chat to connect Resend), authorise your Resend account, then prompt Lovable to use it for whatever emails you need sent.

How do I use my own email domain?

Verify your domain with your email provider (Resend or similar) by adding the SPF, DKIM and DMARC DNS records it gives you, then ask Lovable to send from an address on that domain instead of a shared or test address.

How do I add CAPTCHA to Lovable?

Q: How do I stop spam form submissions?

Add a honeypot field, rate-limit submissions server-side, and validate inputs strictly; for public-facing high-traffic forms, add a CAPTCHA on top.

Short answer

Ask Lovable to integrate a CAPTCHA provider such as Google reCAPTCHA or Cloudflare Turnstile, including the site key on the front end and server-side verification of the token before accepting the submission.

CAPTCHA needs two halves

A CAPTCHA widget alone (the checkbox or puzzle users see) does nothing on its own — the token it produces must be verified server-side before you trust the submission. Skipping that step means the CAPTCHA is decorative.

Steps

Create an account with a CAPTCHA provider (Google reCAPTCHA v2/v3, or Cloudflare Turnstile — Turnstile is generally lighter-weight and privacy-friendlier).
Get a site key (public, goes in the front end) and a secret key (private, must stay server-side).
Prompt Lovable:

Add Cloudflare Turnstile to the contact form. Use this site key: [key]. On submit, verify the token server-side using this secret key before saving the enquiry, and reject the submission if verification fails.

Lovable renders the widget in the form, and adds a server-side check in the function that handles submission — the secret key belongs there, never in front-end code.

Where to store the secret

Never paste the secret key directly into a component. Ask Lovable to store it as a server-side secret and reference it only from the server function.

What usually goes wrong

Verifying only client-side: checking token exists in the browser is trivial for a bot to fake; the secret-key verification call to the provider's API is the part that actually matters.
Forgetting to test the failure path: submit with an invalid/expired token deliberately and confirm it's rejected, not just the happy path.
CAPTCHA on every field-level interaction: only gate the final submit, not every keystroke — that's a UX problem, not a security one.

Is CAPTCHA overkill?

For a low-traffic contact form, honeypot fields plus server-side rate limiting (see how do I stop spam form submissions) often solve the problem with less friction. Reach for CAPTCHA once spam volume actually justifies the extra step for users.
