Welcome to Tempo Checker

Tempo Checker is a real-time validation service that prevents users from signing up with temporary or disposable email addresses, protecting your analytics and server reputation.

We’re excited to launch the new blog for Tempo Checker. We built this product because we were tired of generic blocklists that were already stale the moment they were published. Bad actors cycle through disposable domains too quickly for humans to keep up.

That’s why we rely on active monitoring and AI scraper agents to keep our lists constantly updated in real time.

What’s Next?

We’ll be posting regular updates here on how we catch new types of fake domains, as well as guides for developers on keeping signup flows clean.

Stay tuned!
