Capability

Form failure detection that fills the form and waits for the success page.

A broken form is an invisible outage. Your site looks up. Your customers see the form. The form fails to submit on the back end. Nothing on your dashboard tips you off. SiteGuardian test-submits each form on a schedule and emails you the second the success page stops loading.

What this tool does in one sentence
SiteGuardian test-submits each form on a daily cadence with junk-name values, waits for the success page the form lands on, and emails you the second that success page stops loading.
Best for
Contact, quote-request, lead-gen, and booking forms where a changed webhook URL or a rotated SMTP credential silently drops submissions while the form still returns 200.
Compared to
A periodic manual click-test — SiteGuardian does the test-submit with junk-name fields the CRM is configured to ignore, so the inbox stays empty and the back-end breakage gets caught the same hour.

Form failure detection in depth

  • What it is

    A test-submit probe with a fake entry

    1. Add the URL of the form you cannot afford a silent failure on — contact, quote request, lead-gen, booking.
    2. Pick which fields SiteGuardian fills and the success-page indicator (the URL the form lands on after submission).
    3. The probe runs from outside: no browser extension, no SDK, no site install. CAPTCHA gates are detected and the URL is reported as not testable.

  • Why small businesses run it

    Catch the silent breakage the same hour

    1. A webhook URL changes. An SMTP credential rotates without a code change. The form provider has an outage.
    2. Most contact forms break quietly — the form returns 200, the email never sends, the lead has already moved on.
    3. SiteGuardian’s test-submit cadence catches the breakage the same hour, before the next would-be lead hits the form.

  • What the alert email looks like

    Form failed. URL + timestamp + what the probe saw.

    1. Subject: SiteGuardian — form failed to submit on https://example.com/contact/.
    2. Body: the URL, the UTC timestamp, and a short line on what the probe saw (success-page mismatch, status code, response length).
    3. CAPTCHA-gated forms do not fire false alerts; the alert is "this form has a CAPTCHA gate; manual testing required."
