Know the day your signups quietly stop arriving
A signup form that silently breaks doesn't error - your numbers just flatten. A dead submit button, a form that posts nowhere, a required field that traps everyone. CopyMosaic loads your signup page like a new visitor every day and emails you the day it stops working.
Monitoring is $9/mo for founders, locked forever — up to 5 money pages, billed monthly, cancel anytime.
A broken signup page is uniquely cruel: it looks completely fine, so you keep sending traffic to it for days while not a single person gets through. There's no error on your end, no bounce, no alert - just a slow, quiet flatline in new accounts that's easy to mistake for a slow week. CopyMosaic loads the page the way a new visitor does, checks the things that actually stop a signup, and tells you the day one of them breaks.
What quietly breaks on your signup page
The submit button does nothing
'Get started' or 'Join' loses its handler in a deploy or points at a route that 404s. The form looks ready, the button looks live, and every visitor who fills it in hits a dead end.
The form posts into the void
The form's action URL changes or the endpoint moves, so submissions look like they send but never land. You see a page that works; your database sees nobody.
A required field traps everyone
A validation rule breaks or a field turns silently required, and the form refuses to submit no matter what a visitor types. They try twice, assume it's broken, and leave.
The CTA copy reverts or goes blank
An A/B test rolls back or a CMS edit drops the headline, the offer, or the button label. The page that converted yesterday is now vague or empty, and intent leaks out.
The confirmation path breaks
The post-submit redirect or success state stops resolving, so even people who do get through aren't sure it worked - and the ones who double-submit or bounce never come back.
How it works
Paste your signup or waitlist URL. CopyMosaic loads it like a new visitor, runs about 30 checks on what they'd actually see, and shows you the result in seconds - free, no signup. Turn on monitoring and it re-checks the page every day and emails you the day something changes.

Questions
Can it tell whether the form actually saved my lead?
It checks the outside-visible parts: that the submit control is alive, that the form has a valid action, that the page doesn't 404 or dead-end on submit. It doesn't have access to your database or CRM, so it can't confirm a specific row was written - that's server-side, where an external check can't reach.
Does it work for waitlist and 'notify me' pages too?
Yes. A waitlist, an early-access form, and a newsletter signup are the same shape from the outside: a field, a button, and a path that has to resolve. If any of those quietly breaks, the page still looks fine while it stops collecting anyone.
How often does it check?
Free scans run on demand whenever you paste a URL. Paid monitoring re-checks your signup page - and up to five pages total - every day, and emails you the day something changes.
