Head-to-Head Comparison
Key Findings

Our testing revealed significant differences in contact extraction accuracy. WhoMails led with 94% accuracy, followed by ZoomInfo at 83%. The gap between the best and worst performers was substantial - over 35 percentage points.
2. Decision-Maker Identification Matters
Most tools simply extract any email found in association with a domain. Only WhoMails and ZoomInfo specifically identify and prioritize decision-makers, filtering out technical and support emails.
3. Bulk Processing Capabilities Vary Wildly
For agencies and sales teams processing hundreds of prospects, bulk capabilities are crucial. WhoMails and ZoomInfo excel here, while others have significant limitations.
4. Pricing Doesn't Always Reflect Value
ZoomInfo, despite high accuracy, is 34x more expensive than WhoMails. FindThatLead is cheapest but delivered the worst results, proving that you get what you pay for.
