Product launches

Capture launch-day interest and post-announce signups with one endpoint you can drop on any page.

The problem

Launch pages need reliable intake under traffic spikes without DIY rate limiting.

How Simple Signups fits

Domain-locked endpoint, per-IP limits, optional Turnstile. Export or integrate when the campaign ends.

Working example

Swap in your public campaign id (pub_...) and add your site domain to the campaign allow-list. Full field reference is in the developer docs.

HTML launch notify form

<p>Launching soon. Leave your email and we will notify you the day it goes live.</p>
<form action="https://simple-signups.com/api/subscribe" method="POST">
  <input type="hidden" name="campaignId" value="pub_your_campaign_id" />
  <input type="email" name="email" required placeholder="you@example.com" />
  <input type="text" name="hp" tabindex="-1" autocomplete="off"
    style="position:absolute;left:-9999px" aria-hidden="true" />
  <button type="submit">Notify me</button>
</form>

fetch (JSON)

await fetch('https://simple-signups.com/api/subscribe', {
  method: 'POST',
  headers: { 'content-type': 'application/json' },
  body: JSON.stringify({
    "campaignId": "pub_your_campaign_id",
    "email": "jane@example.com",
    "metadata": {
      "launch": "v1",
      "channel": "product-hunt"
    }
  }),
});

Next step

Create a campaign in the dashboard, copy the public id, and paste the form above onto your site.
