§ 00Quick answerHTML · marketing

Yes — this is the shortest safe path for Astro.

Use the HTML snippet on this page, keep the lead magnet download fields visible in your Astro UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the HTML version, then replace YOUR_ACCESS_KEY.

The posted payload contains first name, work email, company, what's your role?. Required fields are first name and work email.

native astro reality

Astro's whole pitch is shipping zero JavaScript by default.

use case fit

Ungated content gets read; gated content builds your list. The lead-magnet form trades the PDF for an email plus 1-2 qualifying questions, so the nurture sequence segments by intent.

§ 03bLead Magnet Download Form (Ebook / PDF / Checklist Gate)template-specific playbook

The reason this lead magnet download exists.

Multi-step (Typeform-style) · webhooks into ConvertKit / HubSpot / Mailchimp.

why it matters

Lead magnets — ebooks, checklists, templates, swipe files, mini-courses — are the workhorse of B2B content marketing. Gated downloads convert at 25-50% of landing-page visitors (vs 1-2% for newsletter signups), but only when the magnet is truly valuable. The form captures email plus 1-2 qualifying questions ('what's your role?', 'what's your team size?') so the nurture sequence segments by intent. Multi-step boosts completion vs a single form. After submit, the user is redirected to the PDF or it's emailed via webhook + auto-responder. Push the email to your ESP segmented by lead-magnet topic — that's how content marketers build audience taxonomies that actually convert downstream.

route the submission

Step 1: capture email

Single email field — frictionless step 1. Once the email is in, momentum carries through later qualifying questions.

Step 2-3: qualify role / team

One or two questions on role and team size. Optional but most users complete because they're invested. Each answer becomes a tag in the ESP for downstream segmentation.

Deliver the magnet

Auto-respond with the PDF link (or redirect to a thank-you page that auto-downloads). Webhook to ConvertKit / HubSpot / Mailchimp into a 'lead-magnet:[topic]' audience for the nurture sequence.

§ 03cAstro production notesnative path · deploy · gotchas

What changes when this lead magnet download lives in Astro.

These notes come from the Astro platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.

without splitforms

Astro's whole pitch is shipping zero JavaScript by default. A native contact form on Astro means either (a) building a form with no submission target — useless — or (b) standing up an API endpoint via output: 'server' or 'hybrid', which means writing a Node/Bun/Deno handler, picking an email provider, writing your own honeypot logic. Astro 5 added typed Actions, but they're a wrapper around the same underlying fetch — you still deliver the email yourself. The result: every Astro contact-form tutorial ends with 'now configure SendGrid'. Splitforms is the SendGrid-replacement that doesn't require an account, an API key for the email provider, or DNS records for SPF/DKIM.

deploy notes

Astro deploys cleanly to Vercel, Netlify, Cloudflare Pages, GitHub Pages, and any static host with output: 'static'. For Astro Actions (Pattern B), you need output: 'server' or 'hybrid' and a matching adapter (@astrojs/vercel, @astrojs/netlify, @astrojs/cloudflare). On Cloudflare Pages with the Cloudflare adapter, the Action runs in a Worker — keep the splitforms fetch tight (no extra proxying) to stay under the 10ms CPU budget on the free plan. The PUBLIC_ prefix is mandatory for env vars exposed to client-rendered .astro files; vars without it are silently undefined. Lock the key to your *.pages.dev and custom domain.

Astro gotcha

PUBLIC_ prefix is required for client-exposed env vars

Astro mirrors Vite's env-var convention: only variables prefixed with PUBLIC_ are exposed to client-side code (and to .astro files when output: 'static'). If you write import.meta.env.SPLITFORMS_KEY, you'll get undefined at build time. Rename to PUBLIC_SPLITFORMS_KEY.

Astro gotcha

client:load on the form island defeats the point of Astro

If you wrap the form in <MyForm client:load />, you ship a full React/Preact runtime just for one form. Use client:visible (load when scrolled into view) or client:idle (load after main thread is free) instead. For zero-JS forms, skip the island entirely and use a plain HTML form action.

Astro gotcha

Astro Actions need a try/catch or they crash the page

If your action throws, Astro 5's behavior is to render an error page rather than return the error to your form. Wrap the splitforms fetch in try/catch and return { success: false, message } from the action — your form component can then render the message.

Astro gotcha

View Transitions can break form re-submit state

If you've enabled <ViewTransitions /> in your layout, navigating to /contact and back may re-mount the form mid-submission. Add data-astro-reload to the form's submit anchor or guard with if (status === 'loading') return at the top of your handler.

PATTERN A

Pattern A — pure HTML form (zero JS shipped)

The Astro-native approach: a .astro file with frontmatter pulling the key from import.meta.env, then a static <form action> that posts directly. Zero hydration, zero island, zero KB JavaScript. Use the same wiring for the lead magnet download fields on this page.

pattern-a.txtastro10 lines

01---
02const ACCESS_KEY = import.meta.env.PUBLIC_SPLITFORMS_KEY;
03---
04<form action="https://splitforms.com/api/submit" method="POST">

07  <input name="email" type="email" required />
08  <textarea name="message" required />
09  <button type="submit">Send</button>
10</form>

PATTERN B

Pattern B — Astro Action for typed server-side proxying

Astro 5 Actions give you Zod-validated, type-safe form handlers. Use one to keep the access key off the client entirely — the form posts to the action, the action proxies to splitforms. Use the same wiring for the lead magnet download fields on this page.

§ 06Questions9 answered

Lead Magnet Download on Astro — FAQ.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Does this lead magnet download work on Astro?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any Astro site without server-side code, plugins, or SDKs. Drop the snippet into a Astro page or component and submissions land in your inbox via splitforms.com.

02How much does the lead magnet download cost on Astro?

Free for 1,000 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.

03Can I customize the fields?

Yes. The template ships with sensible defaults (first name, work email, company, what's your role?…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the lead magnet download?

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 Astro as on any other framework.

05Can I send the lead magnet download submissions to Slack or Discord?

Yes. Webhooks are free on every plan, 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.

06Will it work on a static Astro 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.

07Should I redirect to the PDF or email it?

Email it. Redirects to a Drive / S3 link mean the user gets the PDF without confirming the email — and the email might be a typo or a temporary address. Email delivery confirms the address by requiring an open. Add a 'didn't get it?' resend button on the thank-you page for the rare typo case.

08Can I integrate with ConvertKit / HubSpot / Mailchimp?

Yes — webhook the JSON into the ESP. ConvertKit's 'tags' map naturally to lead-magnet topics; HubSpot's 'lists' do the same. The nurture sequence triggers on tag-add and the topic-specific drip starts immediately. Most B2B teams use this exact pattern.

09Is gating content GDPR-safe?

If you have EU visitors, the consent for marketing email needs to be explicit and unbundled — meaning a separate checkbox 'I want to receive emails about [topic]' that's not pre-checked and not bundled with 'I accept the download'. Bundled consent has been challenged in EU rulings; unbundled is the safe play.
