Work out which step
is actually failing.
A website action can fail in several different places, and each one needs a different fix. These guides are written to be useful whether or not you ever install anything — including where the answer is that this is not a problem SiteAirbag can see.
Pick the symptom you actually have.
Your site is up but the form is not working
Four checks, in the order the browser runs them: does the button respond, does validation pass, does a request leave the page, and does the visitor get told it worked.
Start here when enquiries stopped and you do not yet know why.
The form says sent but no email arrives
The delivery chain, followed in the order a message travels — stored entry, sending address and authentication, provider log, spam and forwarding rules, then the CRM handoff.
Start here when the visitor saw a thank-you but nothing reached you.
Deciding how to watch for it next time.
Uptime, scheduled tests, analytics and real visitors
Four approaches, four different questions, and what each one genuinely cannot tell you.
Synthetic testing versus real-visitor monitoring
Six trade-offs decided rather than hedged, including the two that go the other way.
Find out before a customer tells you.
SiteAirbag watches one action you choose during real visits and can offer the visitor a backup way to reach you when the evidence shows it failed.
