How to Use Clay for Advanced Data Enrichment

Clay is a data enrichment and automation platform that has become central to modern cold email operations.

What Clay does

Clay connects to 50+ data sources and allows you to build automated enrichment workflows. You input a list of companies or contacts, and Clay enriches each record with data from multiple providers — all in one interface.

Clay enrichment workflow

Step 1: Import your prospect list (from CSV, Apollo, LinkedIn, or CRM). Step 2: Add enrichment columns. For each column, specify the data source and the data point you want. Examples: company revenue from Apollo, technology stack from BuiltWith, recent funding from Crunchbase, LinkedIn headline from LinkedIn. Step 3: Run the enrichment. Clay processes each row automatically. Step 4: Use AI formulas to generate personalized email content based on the enriched data. Step 5: Export the enriched, personalized list to your sending tool.

Clay's AI capabilities

Clay includes AI-powered columns that can generate content based on the enriched data. For example: "Based on this prospect's LinkedIn headline, company description, and recent news, write a personalized opening line for a cold email." This AI layer is what makes Clay transformative for personalization at scale.

Clay's waterfall enrichment

For email finding, Clay can run multiple data providers in sequence (a "waterfall"). If Provider A does not have the email, Clay automatically tries Provider B, then Provider C. This maximizes the coverage and accuracy of your contact data.
