I'm building a tool that catches contact forms dying silently — week 1 of building in public

Three weeks ago I had a simple question: if the contact form on a
small business website breaks tonight, how long until anyone notices?

The honest answer for most sites: weeks. Months, maybe. Uptime
monitors say the site is fine (it is — the page loads). Analytics say
traffic is normal (it is — people still visit). The only thing that
changed is that form submissions quietly stop arriving. Nobody gets an
error message. The business just experiences it as "the phone got
quiet."

So I started building FormPing — a monitoring service that sends a
clearly-labeled synthetic test lead through every lead path on your
site (contact forms, phone links, email fallbacks) every day, and
emails you the moment one stops delivering. Not "is the page up" —
"does a lead actually get through."

WHERE IT'S AT

Week 3 of building, solo, evenings only — and week 1 of writing about
it in public:

The free read-only scanner is live: paste any domain, get a 10-second audit of every way a visitor can reach you — forms, tel: links, email fallbacks. No signup — try it on your own site.
The paid core is live: verify domain ownership with a TXT record, and my bot runs a real test lead through every path daily, with alerts.
Pricing is deliberately simple: $29/mo (5 domains) and $79/mo (20 domains, white-label reports for agencies). Launch code for 50% off the first month.
First dollar: $0. Zero customers, zero replies so far.

WHAT I DID THIS WEEK

Instead of sending another batch of template cold emails (about 80
sent across initial batches and follow-ups, 0 replies — brutal but
expected at this volume), I flipped the approach: I ran my own scanner
against the websites of web agencies — companies that literally sell
lead generation to their clients — and wrote each of them a personal
email about what the scan found on THEIR site. Broken form actions,
missing email fallbacks, forms routing through free third-party
relays, even WAF walls that block form-verification tools entirely.

17 went out across three nights — 8 on Monday, 8 on Tuesday, 1 going
out Thursday. Every email includes a screenshot and a link where they
can reproduce the result in 10 seconds.

EARLY SIGNALS FROM THE SCANNING ITSELF

Scanning agency sites taught me more about my market than any
competitor research did:

The most common "failure" isn't a broken form — it's a form nobody can verify. JS-rendered, no action attribute, iframe-embedded. It probably works. Nobody can prove it.
Several agencies that SELL lead tracking have their own lead paths running through free Gmail relays. Cobbler's children, everywhere.
A surprising number block automated visitors at the firewall — which also blocks the tools that would tell them something's wrong.

THE PLAN

If the personalized scan outreach gets replies, this becomes the main
acquisition channel — it's repeatable, it's genuinely useful to the
recipient, and it's the product demonstrating itself. If it doesn't,
the pivot criteria are already written down.

ASKS

If you've ever lost a lead to a silently broken form — or you run an
agency and have a story about a client's form dying — I'd love to
hear how you found out (or didn't).

Building in public from zero. Numbers will be reported whether
they're good or ugly.

Drafted with AI assistance; every claim and number verified by me.
