ZoomInfo
Enterprise B2B contact and company data platform. ZoomInfo is the data standard RevOps teams at large companies run on, but the cost, contract structure, and aggressive sales tactics make it a love-hate relationship.
In-DepthClay
Waterfall data enrichment with 75+ providers. Clay is the breakout tool for RevOps and GTM engineers who want to build custom enrichment workflows without being locked into a single data vendor's quality ceiling.
In-DepthInstantly
Cold email platform with unlimited sending accounts and built-in warmup. RevOps teams evaluate Instantly when outbound is high-volume email and the priority is deliverability over multi-channel orchestration.
How to Choose
- ZoomInfo has the largest B2B database and enterprise-grade compliance. Higher cost, but data quality and coverage are superior for mid-market and enterprise prospecting.
- Clay offers waterfall enrichment across 75+ data providers. More flexible and often more accurate, but requires RevOps investment to build workflows.
- Instantly focuses purely on cold email delivery at scale. Less data, but better deliverability and unlimited sending accounts.
