Frequently Asked Questions
BlitzAPI FAQ
What makes BlitzAPI different from other B2B data providers?
BlitzAPI distinguishes itself through an API-first architecture built for seamless integration and a fundamental commitment to verified outcomes.

What is the accuracy rate for email data and validation?
BlitzAPI maintains an exceptional email deliverability rate of over 98%. This high rate is sustained by its sophisticated real-time validation technology, which is particularly effective at identifying catch-all domain emails with greater than 98% accuracy.
