Built for Webflow developers who hate operating a backend.
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 newsletter signup 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 total with rule-based spam filtering; paid plans add Slack/Discord webhooks. Webflow's native interactions (success message, loading state) still work if you use fetch instead of a native form submit.
- 500 form submissions total, free to start
- Unlimited forms on every plan, including Free
- Spam protection — honeypot plus a rule-based filter
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.

Setup
Generate, embed, receive.
Three actions stand between you and your first newsletter signup submission — no backend, no database, no CAPTCHA library.
Paste the newsletter signup into your Webflow project
Drop the form snippet into a Webflow page, component, or layout. Replace YOUR_ACCESS_KEY with the key from your dashboard. The form action is a hard-coded URL — no env vars or build-time wiring needed.
Receive submissions
Dashboard updates live on Free. Free includes owner email delivery; paid plans add signed webhooks, CSV export, Slack/Discord forwarding, and BCC to your team.
How SplitForms works
What happens after someone submits your form?
splitforms receives the submission, filters spam, saves it to your dashboard and emails you — then, on paid plans, sends it on to your webhooks and integrations. No backend infrastructure to build.

Where can submissions go besides email?
On paid plans, submissions can also go to Slack, Discord, Google Sheets, Notion, Airtable, Zapier or any signed webhook — and splitforms works on the platforms you build on, from WordPress and Shopify to Next.js. With Stripe connected, your forms can take payments too.

Newsletter Signup on Webflow — answered.
View all FAQsDoes this newsletter signup work on Webflow?
Yes. The form is plain HTML with a single POST endpoint, so it runs on any Webflow site without server-side code, plugins, or SDKs. Drop the snippet into a Webflow page or component and submissions land in your splitforms dashboard.
How much does the newsletter signup cost on Webflow?
Free for 500 submissions — no credit card, no time limit. Pro is $5/mo for 5,000 submissions a month, and Annual is $49/year for 15,000 submissions a month. 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 rule-based filter scores the rest; anything that looks like spam goes to a separate Spam tab instead of your inbox. No CAPTCHA, no friction for human users — and it works the same on Webflow 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 Webflow 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.
