Frequently asked questions
What is waterfall enrichment and why is it superior to single-provider lookups?
Waterfall enrichment queries vendor A; if no valid contact or email is returned, it automatically cascades to vendor B, C, and D. This increases overall contact discovery rates from ~45% to over 80% while only charging for successful lookups.
How do waterfall tools verify email deliverability?
They conduct real-time SMTP handshakes, MX record validation, catch-all detection, and disposable domain filtering to ensure email bounce rates remain well below the 2% threshold.
