Pick the form placement
Popup (highest volume, also highest annoyance — set scroll or exit-intent triggers), inline footer (low volume, low friction), content-end inline (best conversion-quality combo).
Form template · Newsletter signup
Email lists still convert 5-10x social. The newsletter signup form is the single most leveraged piece of your site — pop it up smartly, not annoyingly, and it pays compound interest.
This template is one of our free HTML form templates. See more form templates by industry.
Every template is free and fully editable in the drag-drop builder — swap fields, colors, and the button label before you publish.
No server, API route, or SDK — your Newsletter Signup Form posts straight to one endpoint.
Every submission is emailed to you and saved to a searchable dashboard — spam filtered before it reaches you.
It's plain HTML you own — paste the Newsletter Signup Form snippet, swap in your access key, and ship.
Copy and ship
HTML by default — the same field set also renders as React, Next.js, PHP, and cURL in your dashboard. Every variant posts to the same /api/submit endpoint. Replace YOUR_ACCESS_KEY with the key from your dashboard; that's the only edit.

</p>How to add it
To add a Newsletter Signup Form to your site you need three things: a free splitforms access key, the HTML snippet above, and your key pasted into it. No backend, database, or CAPTCHA library — the form posts to one URL and every submission lands in your inbox and dashboard.
Popup (highest volume, also highest annoyance — set scroll or exit-intent triggers), inline footer (low volume, low friction), content-end inline (best conversion-quality combo).
Webhook the email to ConvertKit / Mailchimp / Substack / Beehiiv / Buttondown. Each has either a native webhook receiver or a Zapier connector. Welcome email fires automatically on add.
EU visitors need explicit consent — add a 'I want to receive emails from [your brand]' checkbox or unbundled-consent text under the email field. Required text varies by jurisdiction; consult your privacy lawyer if in doubt.
What's included
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. Webhooks into ConvertKit / Mailchimp / Substack / Beehiiv / Buttondown.

Where submissions go
Reply-to is wired to the visitor's email, so one tap on Reply answers them directly — while the built-in honeypot and automatic spam scoring filter out bots before they reach you. Every submission is emailed to your inbox and can forward to a webhook or Slack the moment a visitor hits send.

How SplitForms works
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.

Point your form to your unique SplitForms endpoint. That's it.

We instantly capture and organize every submission in your inbox.

Send data to email, spreadsheets, CRMs, webhooks, and 7,000+ apps.

No credit card required. Set up in under 60 seconds.
Connect & automate
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.

Questions
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.
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.
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.
Exit-intent (popup fires when the cursor leaves the viewport heading to the close button) is the lowest-friction popup pattern — the user was leaving anyway. Conversion typically runs 2-4%. Avoid load-time popups that block the page on first impression — those tank time-on-site.
