§ 00Carrd + Feedback Formplatform-specific integration guide

Why Carrd developers choose splitforms for feedback form

Carrd's embed element lets you inject custom HTML into your one-page site — perfect for a lightweight contact form. Carrd Pro includes a native form feature, but it caps submissions at 100/month on paid plans and lacks webhook delivery. The feedback form on this page drops into a Carrd embed, posts to splitforms, and gives you 500 dashboard submissions/month free; Starter adds Slack/Discord notifications. No Carrd Pro upgrade needed for the form to work. The HTML is self-contained — Carrd's minimal runtime handles the display, splitforms handles the backend.

§ 00Quick answerHTML · feedback

Yes — this is the shortest safe path for Carrd.

Use the HTML snippet on this page, keep the feedback form fields visible in your Carrd 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 carrd reality

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.

§ 03cCarrd production notesnative path · deploy · gotchas

What changes when this feedback form lives in Carrd.

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

without splitforms

Carrd's Form widget requires Pro Standard ($19/year) just to exist on the page, and even then it doesn't deliver email itself — the form 'works' by posting to an external integration: Mailchimp, SendGrid, Basin, Formspree, etc. So the question isn't 'native vs splitforms' but 'which third-party backend do you wire up?'. Mailchimp is overkill (and surprisingly expensive once your list grows); Basin and Formspree limit free submissions; SendGrid requires DNS verification. Splitforms is the same shape of integration (Type: Custom, Method: POST, Action: a URL) at a better free tier and with built-in spam filtering. Carrd's Form widget settings don't change.

deploy notes

Carrd publishes to a *.carrd.co subdomain on every plan; Pro Standard adds a custom domain. The form posts to splitforms from the browser, so neither subdomain nor custom domain matters for delivery. Lock the splitforms access key to BOTH the *.carrd.co URL and your custom domain — Carrd serves the same content under both, with different Origin headers. Carrd's Designer preview never actually POSTs; you have to publish (free) and submit from the live URL to test. Embed elements bypass Carrd's CSS, so the form will look browser-default unless you inline styles.

Carrd gotcha

Pro Standard plan still required for Custom form Type

Carrd's free plan and Pro Lite don't expose the Form widget at all. Pro Standard ($19/yr) unlocks the Form widget with Type → Custom. Splitforms doesn't change Carrd's plan requirements — it just fills in the backend that Carrd doesn't ship.

Carrd gotcha

Embed element forms don't inherit Carrd's site styles

If you paste raw HTML via an Embed element, your form will look like browser-default — no Carrd typography, no site colors. Use the native Form widget for styling, then add a hidden access_key field via Custom fields.

Carrd gotcha

Carrd's success message + splitforms redirect can fight each other

Carrd's Form widget has a built-in success message that shows on 2xx response. If you also set a redirect field in the form, the user sees the success blip then redirects mid-message. Pick one: redirect via splitforms OR Carrd's success text.

Carrd gotcha

The form widget's Field labels don't match input names by default

Carrd uses friendly labels like 'Your name', but the actual input name attribute is name-1 or similar unless you set Custom in the field settings. Set the Custom name to name, email, message — splitforms uses the input names as keys in your inbox.

PATTERN A

Pattern A — native Form widget set to Custom type

In the Form widget's settings, set Type to Custom, Method to POST, Action to the splitforms URL. Add a hidden field access_key via the Custom Fields tab. Carrd handles the styling and mobile layout; splitforms handles delivery. Use the same wiring for the feedback form fields on this page.

07  <button type="submit">Submit</button>
08</form>

PATTERN B

Pattern B — Embed element with full HTML control

Drop an Embed element into a Carrd section and paste raw HTML. Loses Carrd's auto-styling but lets you add a honeypot, multi-field validation, or custom redirect. Useful for waitlist or job-application forms that exceed the Form widget's capability. Use the same wiring for the feedback form fields on this page.

§ 06Questions9 answered

Feedback Form on Carrd — FAQ.

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

01Does this feedback form work on Carrd?

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

02How much does the feedback form cost on Carrd?

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 Carrd 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 Carrd 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.
