53,800 leads, emails not included so you enrich them yourself · Free
53,800 US marketing agencies and services, built in Clay for 2026. Every row has the company and firmographic detail; emails are not included, so this is a universe you enrich yourself.
Who this is for: tool vendors selling into agencies, white-label and fulfillment providers, and anyone with an agency-partner motion.
Before you send: append and verify emails first. This is the toughest crowd you can email, agencies run cold email themselves and spot a template instantly, so personalize hard, reference something real about the agency, and run copy through the Spam Checker. Short, sharp, specific. CAN-SPAM basics on every send.
