Tracking HeavySet Tech Email Submissions with Simpli.fi

Use the snippet below to ensure every email capture (emailSubmission) that occurs inside your HeavySet Tech form is credited to your Simpli.fi campaign.

---

1. Prerequisites

✔  You already have a HeavySet Tech form (iframe or widget) embedded on your page.

✔  Simpli.fi has supplied your unique tag URL (e.g. https://tag.simpli.fi/sifitag/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

✔  You can edit the page HTML.

2. Add the script

Copy the snippet below—replace <SIMPLIFI-TAG-URL> with the exact URL provided by Simpli.fi—and paste it directly after your HeavySet Tech embed (ideally just before </body>):

<!-- HeavySet → Simpli.fi emailSubmission listener -->
<script>
/* inject Simpli.fi tag once per emailSubmission */
function loadSimpliFiTag() {
  if (window.__simpliFiHSLoaded) return;
  window.__simpliFiHSLoaded = true;

  const s = document.createElement('script');
  s.async = true;
  s.src = '<SIMPLIFI-TAG-URL>'; /* provided by Simpli.fi */
  document.body.appendChild(s);
}

/* listen for HeavySet Tech postMessage events */
window.addEventListener('message', (event) => {
  if (!event.origin.includes('heavyset.tech')) return;

  const t = event.data?.type;
  if (t === 'emailSubmission') loadSimpliFiTag();
});
</script>

Why this works

• The HeavySet Tech embed emits a postMessage when a visitor successfully submits an email (event.data.type === "emailSubmission").

• The listener waits for that message and dynamically injects the Simpli.fi tag, ensuring the tag only fires after consent is gathered and a real submission occurs.

• The guard window.__simpliFiHSLoadedprevents duplicate loads if a visitor submits the form multiple times in one session.

3. Test it

1. Publish the page.

2. Submit a test email through your form.

3. In DevTools → Network, filter by your Simpli.fi tag URL and confirm it returns HTTP 200 or 304.

4. If the request is missing, verify that:

   • The Simpli.fi URL is correct.

   • The script sits below the form embed.

   • The browser console shows no JavaScript errors.

4. Troubleshooting & Tips

• "Script already executed" – Make sure you removed any earlier standalone Simpli.fi script tags so the tag only comes through the listener.

• Multiple submissions – The guard flag prevents duplicates; if you do need multiple fires, remove the if (window.__simpliFiHSLoaded) return; line.

• Consent frameworks – If you rely on a CMP, the listener fires only after the email submission event, which typically follows user consent. For more granular logic, expand loadSimpliFiTag() with your CMP checks.
