This Clay.com review covers the platform after its March 2026 pricing overhaul — the biggest pricing change in the company’s history. Waterfall enrichment hits 78% email match rates versus 42% for single-source tools. The credit system is unpredictable, the learning curve runs 4–6 weeks, and the 30% top-up markup never appears on the pricing page. Powerful tool. Wrong buyer pays a steep price.
