Frequently Asked Questions

BlitzAPI FAQ

What makes BlitzAPI different from other data providers?

We're built API-first for seamless integration, and we operate on a deliverability-first principle. You pay only for verified, accurate results—not for noise. Our focus is on providing high-quality data that works within your existing GTM playbooks, not forcing you to adapt to a clunky platform.

How accurate is the email validation, especially for catch-alls?

Our catch-all email validation is a game-changer, with a proven accuracy rate of over 98%. We use advanced, real-time techniques to determine if an address on a catch-all domain is likely to deliver, drastically reducing bounce rates and protecting your sender reputation.

What does "pay only for verified results" mean?

Unlike providers that charge for every lookup, we often use a credit system where you are only charged for successful, verified enrichments. If we can't find a valid email or phone number, you typically don't pay. This aligns our success with yours and eliminates wasted spend.
