Contact Form (with phone) for Webflow
Name, email, phone, company, reason — for B2B inquiries that need qualification. Free for 500 submissions per month — no backend, no SDK, no plugin.
Why Webflow developers choose splitforms for contact form (with phone)
Webflow's built-in form block sends to Webflow's own backend, which caps at 100 submissions/month on the free plan and lacks webhook delivery, CC recipients, and spam filtering. The contact form (with phone) on this page bypasses that entirely — paste it into a custom embed element, set the form action to splitforms, and you get 500 dashboard submissions/month with AI spam filtering; Starter adds Slack/Discord webhooks. Webflow's native interactions (success message, loading state) still work if you use <code>fetch</code> instead of a native form submit.
Yes — this is the shortest safe path for Webflow.
Use the HTML snippet on this page, keep the contact form (with phone) fields visible in your Webflow UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.
Paste the HTML version, then replace YOUR_ACCESS_KEY.
The posted payload contains full name, work email, phone, company, what's this about?, message. Required fields are full name, work email, phone, what's this about? and message.
Webflow's built-in Forms feature delivers submissions to your Webflow project dashboard and emails them — but the free Site plan caps submissions (50 per site, lifetime, on legacy plans) and webhooks are gated behind the Workspace plan ($24/mo+).
A contact form with a phone number field that auto-formats as the user types — (555) 123-4567 emerges from raw digits. Pure pattern validation, optional JS mask for the live formatting.

The reason this contact form (with phone) exists.
Mobile-friendly numeric keypad, live mask, format-tolerant.
Phone fields suffer from format chaos — users type +1 555 123 4567, (555) 123 4567, 555.123.4567, 5551234567. Three options: accept anything and normalize server-side (best for international), use a pattern attribute for client-side validation (good for US-only), or apply a JavaScript mask that formats as the user types (highest conversion, more code). splitforms accepts any format and your form's UX is whichever approach fits your audience.
Use type="tel" not type="text"
Mobile keyboards open the numeric keypad for tel inputs. Desktop accepts the same characters as text but signals intent.
Add a pattern attribute for validation
`pattern="[0-9() +-]+"` allows the common phone characters. Or use a strict US format: `pattern="\(?\d{3}\)?[ -]?\d{3}[ -]?\d{4}"`.
(Optional) Add the JS mask
On input, strip non-digits and reformat to `(XXX) XXX-XXXX`. The mask runs on every keystroke, giving live formatting feedback.
What changes when this contact form (with phone) lives in Webflow.
These notes come from the Webflow platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.
Webflow's built-in Forms feature delivers submissions to your Webflow project dashboard and emails them — but the free Site plan caps submissions (50 per site, lifetime, on legacy plans) and webhooks are gated behind the Workspace plan ($24/mo+). Worse, the form fails silently if you exceed the cap: users see the 'success' state, your inbox gets nothing. There's no API to inspect submissions programmatically below the Workspace tier, and CMS-driven forms inherit the same caps. Native is fine for a personal portfolio with three submissions a year; for any real lead capture, you need an external endpoint. Splitforms is that endpoint without the plan upgrade.
Webflow hosts your published site on its own CDN — there's no Vercel/Netlify config to worry about. The form posts cross-origin to splitforms regardless. Disable Webflow's built-in hCaptcha for the form (Form Settings → Spam Filter → Off) — it intercepts submissions client-side before splitforms is reached. Lock the splitforms access key to BOTH your *.webflow.io staging URL and your custom domain in the dashboard; Webflow serves both, with different Origin headers. Custom code embeds count toward Webflow's per-page code limit (10 KB) — keep raw-HTML Embed forms tight if you have multiple per page.
Webflow strips custom hidden inputs from native Form Blocks
If you add <input type="hidden" name="access_key"> directly in Designer's Form Block, Webflow ignores it on publish. Use the Form Block's settings panel: Form Settings → Form Name + add custom attribute. Or use an Embed element with raw HTML if you need full control.
Default action URL gets reset on every Designer save
Setting the Action URL to https://splitforms.com/api/submit in the Form Block sometimes reverts to Webflow's default after a publish. The fix: lock it in by adding a custom attribute action to the form element (Settings → Element Settings → Custom Attribute).
Method must be set to POST in the form's settings, not the URL
Webflow forms default to GET. Open the form's Settings panel, change Method to POST. If you forget, the submission posts your fields as URL query params — splitforms returns a 405 Method Not Allowed.
Webflow's success/error elements still trigger on AJAX submit
Webflow auto-shows the .w-form-done div on a 2xx response. That's good — but if you also set up a redirect field in splitforms, the user sees the success message for ~80ms before the redirect fires. Either remove the success div or skip the redirect field.
Pattern A — native Form Block with overridden action URL
Use Webflow's drag-and-drop Form Block — keep the styling, structure, and Designer integration. In Form Settings, change Action to https://splitforms.com/api/submit and Method to POST. Add a hidden access_key field via the form's settings panel. Submissions skip Webflow's backend entirely. Use the same wiring for the contact form (with phone) fields on this page.
Pattern B — Embed element with raw HTML
If you need full control over markup (custom honeypot, file upload, multi-step), drop an Embed element on the canvas with raw HTML. Skips Webflow's form widget entirely. Useful for forms that don't fit the Designer's mental model. Use the same wiring for the contact form (with phone) fields on this page.
