Why This Stack Works Together

Traditional all-in-one CRMs cost thousands and lack sophisticated automated enrichment. Combining Clay with dedicated sequencers gives small teams enterprise-grade prospecting capabilities.

How to Set It Up

1. Setup 3 secondary domains on Smartlead. 2. Create your master ICP list in Clay using waterfall lookup. 3. Sync enriched leads directly to Attio CRM.
