Loved the demo — quick question about pricing on the 4-year plan. Are usage limits per project or account-wide?

§ 06Questions6 answered

Newsletter Signup on Carrd — FAQ.

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

01Does this newsletter signup 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 inbox via splitforms.com.

02How much does the newsletter signup cost on Carrd?

Free for 1,000 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 4-year plan (15,000 submissions/mo for 48 months). The same pricing applies regardless of which framework hosts the form.

03Can I customize the fields?

Yes. The template ships with sensible defaults (your email…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the newsletter signup?

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 newsletter signup submissions to Slack or Discord?

Yes. Webhooks are free on every plan, 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.
