Frequently asked questions
How does BlitzAPI find emails?
Emails are discovered from identity signals, company context, domain logic, and real-world data points attached to the contact. They are never guessed from name patterns: an address we cannot prove comes back Not Found.
Are the emails verified before I get them?
Yes. Every address goes through the catch-all validation layer, which works out whether an address on a permissive domain can actually be proven. Only proven addresses are delivered; anything we cannot prove comes back Not Found instead of a maybe.
Can I use it at outbound scale?
The API is built for high-volume enrichment: complete prospect lists, CRM records, and automated sequences without per-record manual checks.
