Why Email Finder Accuracy Matters More Than Database Size

The vanity metric

Every prospecting tool advertises database size — 100M, 275M, 500M contacts. What they don’t advertise: how much of it is stale, and what a 30% bounce rate does to your sender reputation.

What bounces actually cost

Hard bounces above ~5% get your domain flagged. Recovering deliverability takes weeks. Cheap data that bounces is the most expensive data you can buy.

Verified-at-lookup: the better model

DazLeads verifies contact data at the moment of lookup — and if a delivered email still bounces, the credit is automatically refunded. You literally cannot pay for a bad contact twice.

How to evaluate any tool

• Run the same 20 prospects through your current tool and the alternative.
• Track actual delivered-and-not-bounced rate, not “results returned”.
• Include cost-per-verified-contact, not cost-per-row.
