Catch bad email addresses in your own signup form

One script tag. It flags typos and disposable addresses inline, before a bad address ever reaches your database. No account required, no cookies, and it never blocks form submission.

<script src="https://autorev.rohnelt.dev/embed.js" data-auto="all" defer></script>

Or opt in field by field:

<input type="email" name="email" data-verify>

What it does

• Typo correction. gmial.con becomes a “did you mean gmail.com?” prompt with a one-click fix.
• Disposable detection. 190 throwaway providers, matched including sub-domains.
• Reachability. Live MX lookup, so a domain that cannot receive mail is caught at the form.

The honest limits

• The widget is anonymous and rate limited to 60 checks per minute per site. That is plenty for a normal signup form and deliberately not enough for bulk list cleaning - that is what the API is for.
• It is client-side, so treat it as a helpful hint, not a security control. Validate server-side too (one API call).
• It renders a small “verified by Veritas” link. That link is how this stays free.
• The widget speaks the visitor’s language too - it is served in whatever language their browser asks for.
