§ 00HTML + Feedback Formplatform-specific integration guide

Why HTML developers choose splitforms for feedback form

Plain HTML sites have zero built-in form delivery — <code>mailto:</code> links open broken email clients, shared-hosting PHP is vanishing, and setting up Node just for a contact form is overkill. splitforms gives you a production-grade submission pipeline from a single <code><form action></code>. No build step, no framework lock-in, no server-side code. The feedback form on this page posts standard <code>application/x-www-form-urlencoded</code> data — the same format browsers have used since 1999 — so it works on every host from GitHub Pages to S3 to Apache.

§ 00Quick answerHTML · feedback

Yes — this is the shortest safe path for HTML.

Use the HTML snippet on this page, keep the feedback form fields visible in your HTML UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the HTML version, then replace YOUR_ACCESS_KEY.

The posted payload contains how would you rate your experience?, what can we do better?, email (optional, for follow-up). Required fields are how would you rate your experience? and what can we do better?.

native html reality

Plain HTML has no built-in way to deliver a form submission anywhere — the spec only covers serializing fields and either GETting or POSTing them to whatever URL you put in action.

use case fit

Customer feedback is the cheapest product research you have. The form captures NPS / CSAT plus an open comment — and routes negative responses to a Slack channel for same-day triage.

§ 03bCustomer Feedback Form (NPS / CSAT / Open-Ended)template-specific playbook

The reason this feedback form exists.

Webhooks into Slack / Linear / Productboard · NPS detractor triage in minutes.

why it matters

Feedback forms cost almost nothing to ship and pay back disproportionately — every NPS detractor (score 0-6) is a conversation that prevents churn, every promoter (9-10) is a referral or testimonial source. The form is simple: 0-10 rating, an optional comment, and an email. The leverage is in the routing: detractors auto-DM your support lead in Slack within minutes, promoters get a 'mind leaving us a G2 / Trustpilot review?' follow-up, passives go into a digest. Survey tools (SurveyMonkey, Typeform, Hotjar) charge $30-100/mo for the same pattern. The form pattern is 30 lines of HTML.

route the submission

Capture rating + comment

Required: 0-10 NPS rating (or 1-5 CSAT for transactional surveys). Optional: comment textarea, email for follow-up. Keep it minimal — long surveys tank completion.

Route by score

Webhook branches on score: 0-6 (detractors) DM Slack support channel; 7-8 (passives) go to weekly digest; 9-10 (promoters) trigger a G2 / Trustpilot review-request email.

Push to your tools

Detractor comments to Linear / Productboard for product triage. Promoter quotes to a 'testimonials' Notion database for marketing. Raw data to a CSV / BigQuery / dbt warehouse for trend analysis.

§ 03cHTML production notesnative path · deploy · gotchas

What changes when this feedback form lives in HTML.

These notes come from the HTML platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.

without splitforms

Plain HTML has no built-in way to deliver a form submission anywhere — the spec only covers serializing fields and either GETting or POSTing them to whatever URL you put in action. Without a backend, the historical fallback is mailto: links (broken on Gmail, Outlook web, and most mobile devices) or PHP on shared hosts (extinct on S3, GitHub Pages, Cloudflare Pages, Netlify-static). That's the gap splitforms fills: you keep using the same <form action method=POST> HTML you already wrote, and the action points at our endpoint instead of a server you'd otherwise have to operate.

deploy notes

Plain HTML deploys to anywhere that serves files: GitHub Pages, S3 + CloudFront, Cloudflare Pages, Netlify, Vercel, plain Apache/nginx, even Dropbox public folders (RIP). The form posts cross-origin from the browser to splitforms.com, so the host is irrelevant to delivery — but enforce HTTPS on your domain, otherwise the browser blocks the mixed-content POST. On GitHub Pages, toggle 'Enforce HTTPS' under Settings → Pages. On S3, terminate TLS at CloudFront. Lock the splitforms access key to your custom domain in the dashboard so a leaked key from View Source is inert elsewhere.

HTML gotcha

method="GET" turns your form into a URL query string

If you forget method="POST" (or omit it — GET is the HTML default), the browser appends form fields to the URL: ?name=Maya&email=…. Splitforms's endpoint returns 405 Method Not Allowed because it only accepts POST. Always specify the method explicitly.

HTML gotcha

Multiple inputs with the same `name` only send the last value

If you accidentally name two fields email, FormData posts both — but the splitforms dashboard shows the last one. For checkbox groups, use name="interests[]" or unique names per checkbox.

HTML gotcha

File inputs require enctype="multipart/form-data"

Standard forms submit as application/x-www-form-urlencoded, which can't carry binary file data. If you add <input type="file">, also add enctype="multipart/form-data" to the form tag — otherwise the file silently doesn't upload.

HTML gotcha

Hidden honeypot field needs to be invisible to bots' DOM parsers

style="display:none" is what splitforms uses, but some sophisticated bots ignore display:none. Stack defenses: display:none + tabindex="-1" + aria-hidden="true" + an off-screen label. Splitforms's classifier catches the rest.

PATTERN A

Pattern A — pure HTML with redirect-on-success

The simplest possible setup: zero JavaScript, full graceful degradation, the browser handles the round-trip. Splitforms 302s to your redirect URL on success, so users always land on a thank-you page even with JavaScript disabled or a flaky network. Use the same wiring for the feedback form fields on this page.

pattern-a.htmlhtml9 lines

01<form action="https://splitforms.com/api/submit" method="POST">
02  <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />

07  <input type="checkbox" name="botcheck" style="display:none" tabindex="-1" />
08  <button type="submit">Send</button>
09</form>

PATTERN B

Pattern B — HTML with progressive-enhancement fetch

Same HTML, plus a tiny inline <script> that intercepts the submit, posts via fetch, and renders inline status — without a framework. Falls back to native form behaviour if JS fails to load. Use the same wiring for the feedback form fields on this page.

§ 06Questions9 answered

Feedback Form on HTML — FAQ.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Does this feedback form work on HTML?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any HTML site without server-side code, plugins, or SDKs. Drop the snippet into a HTML page or component and submissions land in your splitforms dashboard.

02How much does the feedback form cost on HTML?

Free for 500 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 3-year plan (15,000 submissions/mo for 36 months). The same pricing applies regardless of which framework hosts the form.

03Can I customize the fields?

Yes. The template ships with sensible defaults (how would you rate your experience?, what can we do better?, email (optional, for follow-up)…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the feedback form?

A hidden honeypot field catches dumb bots, and a tuned classifier scores the rest. You only see real submissions in your dashboard. No CAPTCHA, no friction for human users — and it works the same on HTML as on any other framework.

05Can I send the feedback form submissions to Slack or Discord?

Yes. Webhooks are available on Starter and above, with auto-formatted payloads for Slack, Discord, and WhatsApp (via CallMeBot). Or send raw signed JSON to any URL — Zapier, n8n, your own server. Configure in the splitforms dashboard.

06Will it work on a static HTML site?

Yes — the form posts directly to splitforms from the browser, so no server is involved. Works on Vercel, Netlify, GitHub Pages, Cloudflare Pages, S3, or any plain Apache host.

07Should I use NPS or CSAT?

NPS (0-10) for relationship surveys ('how likely are you to recommend us?') sent quarterly or after major moments. CSAT (1-5) for transactional surveys ('how was this support ticket?') sent right after the interaction. Different questions, different cadences, both common patterns.

08Will I get response bias from a public form?

Yes — open-link feedback skews toward people with strong feelings (positive or negative). For statistically representative measurement, send the survey via email to a random sample of users. The public form catches the heat-of-moment feedback you'd otherwise miss.

09Can I push to Slack / Linear / Productboard?

Yes — webhook the JSON. Slack has incoming webhooks (free); Linear and Productboard accept inbound issue creation via Zapier or native APIs. Detractor comments showing up as a Linear issue with the rating prefilled in the title is a powerful workflow.
