</form>SvelteKit + Newsletter Signup
Built for SvelteKit developers who hate operating a backend.
Svelte's lightweight runtime is one of its biggest selling points — adding a heavy form library defeats the purpose. The newsletter signup on this page keeps that promise: it uses Svelte's native on:submit directive and a fetch POST, with no external dependencies. The form state lives in a simple let variable, not a store or a state machine. In SvelteKit, you could alternatively use a +page.server.ts action, but that couples your form to SvelteKit's server-side runtime — splitforms decouples it so the same form works on static hosts and other frameworks.
- 500 form submissions per month, free forever
- Unlimited forms on every plan, including Free
- Spam protection — honeypot plus a tuned classifier
Newsletter Signup fields
What every field actually does.
The posted payload contains your email. Required fields are your email. Rename, remove, or add your own — splitforms accepts any name you POST.
- Your email — Reply-to address — splitforms wires this so hitting reply goes back to the sender.
Template playbook
The reason this newsletter signup exists.
Newsletter conversion benchmarks haven't moved much: ConvertKit / Substack landing pages convert at 1-2% of visitors, popup forms at 2-4%, content-upgrade lead magnets at 8-15%. The form itself is trivially simple (email field, optional name) but where it lives matters — exit-intent popup, scroll-triggered slide-in, footer inline, content-end inline all behave differently. Push the submission to your ESP (Mailchimp / ConvertKit / Substack / Beehiiv / Buttondown) via webhook so the welcome email fires automatically. GDPR / CASL require explicit consent — a checkbox or unbundled-consent text under the form covers it for EU and Canadian visitors.

Testimonials
Loved by developers shipping at every scale.
40 quotes on record — from indie hacks to agency migrations.
“I replaced a Lambda + DynamoDB + SES contact form with six lines of HTML. It took eleven minutes, and the dashboard is better than what I was going to build.”
“We migrated 14 client sites off Formspree in a single weekend. The price is a third of what we paid, the API is more honest, and the spam filter actually works.”
“The webhook payload is signed, idempotent, and well-shaped. It reads like code from a competent team, not a CRUD app held together with duct tape.”
“I stopped reaching for Typeform on small marketing sites. splitforms covers 90% of the use case at none of the bloat.”
“I onboarded our whole agency in an afternoon. The MCP integration meant Cursor literally dropped the form straight into our client repos for us.”
“The free plan gave me 500 submissions before I paid a cent, and Pro is five dollars a month. I've spent more on coffee deciding which backend to use.”
“Spam went from forty junk entries a day to zero, with no reCAPTCHA puzzle ruining the form. The honeypot and time-trap just quietly do their job.”
“Point the form action at one endpoint and you're done. No SDK, no client library, no build step. This is how a form backend should feel.”
“Leads land in Slack the second someone submits, and a copy goes to Google Sheets for the sales team. I wired both up in under ten minutes.”
“I run a static Hugo site on a five-dollar VPS. splitforms gave it a real contact form without me standing up a single server.”
Common questions
Newsletter Signup on SvelteKit — answered.
View all FAQsDoes this newsletter signup work on SvelteKit?
Yes. The form is plain HTML with a single POST endpoint, so it runs on any SvelteKit site without server-side code, plugins, or SDKs. Drop the snippet into a SvelteKit page or component and submissions land in your splitforms dashboard.
How much does the newsletter signup cost on SvelteKit?
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.
Can 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.
How 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 SvelteKit as on any other framework.
Can I send the newsletter signup submissions to Slack or Discord?
Yes. Webhooks are available on paid plans, 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.
Will it work on a static SvelteKit 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.
Will my form trigger GDPR consent requirements?
If you have any EU or UK visitors, yes — GDPR requires explicit, freely-given consent for marketing emails. Add a separate consent checkbox (not pre-checked) below the email field. Same applies to CASL in Canada and PECR in the UK. US-only audiences fall under CAN-SPAM, which is less strict but still requires honest unsubscribe handling.
How do I push to ConvertKit / Mailchimp / Substack / Beehiiv?
Webhook the submission as JSON. ConvertKit has a native webhook receiver per form; Mailchimp accepts via API or Zapier; Substack accepts via Beehiiv/Substack import API or Zapier; Beehiiv has direct webhook support. The newsletter platform fires the welcome sequence automatically on add.
Does double opt-in hurt list growth?
Double opt-in drops list size by 20-30% but improves deliverability and engagement metrics — single-opt-in lists accumulate spam-trap addresses that tank inbox placement. Most serious senders run double opt-in for that reason. Substack and Beehiiv default to it.
