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.
