?>WordPress + Newsletter Signup
Built for WordPress developers who hate operating a backend.
WordPress contact form plugins (Contact Form 7, WPForms, Fluent Forms) work but add database bloat, update fatigue, and a monthly subscription for features like webhook delivery or advanced spam controls. The newsletter signup on this page drops into a Custom HTML block — no PHP, no plugin activation, no settings page to configure. Every field POSTs to splitforms as standard form data, so your WordPress admin stays clean. You keep using WordPress for content management and page building while splitforms handles the form pipeline.
- 200 form submissions total, free to start
- 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 had an AI agent build a lead-capture flow, and splitforms was the backend it chose on its own through MCP. It just worked end to end.”
“Switched from Web3Forms because I wanted a real dashboard, not just an email relay. Same simplicity, far more once the lead arrives.”
“The autoresponder lets us send a clean confirmation email to every applicant automatically. Candidates feel looked after and we don't lift a finger.”
“I teach a web dev course and tell every student to use splitforms for their portfolio contact form. Free, no card, and they learn how a real API works.”
“Exports are a single click to CSV with every field intact. Reconciling leads against our CRM stopped being a Monday-morning chore.”
“I evaluated five form backends in an afternoon. splitforms was the only one whose docs didn't hide the pricing or the rate limits. That earned the signup.”
Common questions
Newsletter Signup on WordPress — answered.
View all FAQsDoes this newsletter signup work on WordPress?
Yes. The form is plain HTML with a single POST endpoint, so it runs on any WordPress site without server-side code, plugins, or SDKs. Drop the snippet into a WordPress page or component and submissions land in your splitforms dashboard.
How much does the newsletter signup cost on WordPress?
Free for 200 submissions total — 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 WordPress 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 WordPress 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.
