Clay is a powerful data enrichment and workflow platform that has become central to sophisticated cold email operations in 2026.
What Clay does
Clay connects to multiple data sources — LinkedIn, Apollo, Clearbit, Google, Crunchbase, and dozens more — and lets you build automated workflows that enrich prospect data, research companies, and create personalized email copy at scale.
Why Clay matters for cold email
The best cold emails reference specific details about the prospect and their company. Manual research does not scale. Clay automates the research process by pulling data from multiple sources and structuring it for use in email personalization.
Common Clay workflows for cold email
Company research workflow: Input a list of company domains. Clay enriches each with company size, industry, funding, recent news, technology stack, and key personnel. Output a fully enriched company list. Prospect research workflow: Input a list of prospect LinkedIn URLs. Clay pulls their recent posts, job history, mutual connections, and interests. Output personalization data for email copy. AI personalization workflow: Feed enriched data into an AI module within Clay to generate personalized opening lines or email drafts for each prospect.
Getting started with Clay
Clay has a learning curve but significant payoff. Start with a simple enrichment workflow — inputting company domains and outputting enriched data. Once comfortable, build more complex workflows that combine multiple data sources and AI.
