Form failure monitoring: catching the day your “Send” button silently broke.
A form that looks like it sends but does not is the most expensive form of downtime. The “Send” button still looks like a button; the page still renders; the submission returns a thank-you page; the inbox gets quiet two days later. Form failure monitoring catches that on day one.
- Daily submit-test against your real form endpoint.
- Watches the thank-you URL. Not the form provider’s dashboard.
- No form-side hookup. No SMTP credential. No provider OAuth grant.
- One short email per failure; one recovery email per come-back.
- Free on every SiteGuardian plan. Starter, Pro, and Lifetime.
How it works
Setup, in three beats.
Step 01
Point SiteGuardian at your public form endpoint
Paste the URL the form posts to (or the URL it lands on after success). Set one field. Typically a name and an email. SiteGuardian submits daily with the same payload a visitor would send. The fix-shaped test that reveals the day the form silently broke.
Step 02
Let the daily cadence catch the silent submit failure
Most form failures are silent: the form looks intact; the “Send” button still fires; the response is a thank-you page; the inbox gets quiet three days later. SiteGuardian’s daily submit-test catches the failure the day it happens, with the URL, the response code, and the failed field in the alert.
Step 03
Patch the form before the next two days of inquiries pile up
A form that silently stops sending is more expensive than a form that visibly 500s. The latter is loud; the former goes unnoticed for two days, then costs a week’s worth of missed inquiries. Form monitoring is the day-one signal, not the day-five discovery.
What the alert actually says
One email. One URL. One timestamp.
Your contact form on https://example.com/contact/ returned HTTP 500 at 09:14 UTC. The probe will retry in 24 hours. Field failures last 24 hours; if the next probe passes, the alert stays silent.Frequently asked
