Bootstrap provides the grid system, form controls, validation states, and responsive utilities that make forms look professional out of the box. The newsletter signup on this page adds Bootstrap classes for layout (.row, .col-md-6, .form-control) while posting to splitforms for the backend. This combination is popular with agencies still shipping Bootstrap-based WordPress themes — the client sees a polished, responsive form, and you get reliable delivery without PHP mail or a WordPress plugin.

Newsletter Signup fields
The posted payload contains your email. Required fields are your email. Rename, remove, or add your own — splitforms accepts any name you POST.

Template playbook
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
Three actions stand between you and your first newsletter signup submission — no backend, no database, no CAPTCHA library.
Sign in at splitforms.com — your access key is created instantly. No credit card, no setup wizard, no SDK to install.
Drop the form snippet into a Bootstrap 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.
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
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.

Common questions
Yes. The form is plain HTML with a single POST endpoint, so it runs on any Bootstrap site without server-side code, plugins, or SDKs. Drop the snippet into a Bootstrap page or component and submissions land in your splitforms dashboard.
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.
Yes. The template ships with sensible defaults (your email…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.
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 Bootstrap as on any other framework.
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.
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.
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.
