Clay is a strong choice for building enrichment and data workflows. Cluster brings that preparation into a product that also sends on LinkedIn and email. Find accounts, identify the right people, check their fit, and build the campaign around what you learned, with both sending channels ready when you are.
Clay now has its own email sequencer. The difference is LinkedIn: Clay routes that outreach through a connected tool. Cluster supports LinkedIn and email steps in the same native campaign, so you can set the message order and delays without coordinating a second sending platform.
A new role, a funding round, or a hiring push can give you a reason to reach out. Cluster lets you research the company and person behind that event, qualify the opportunity, and use the findings in your messages. Clay also supports signals; Cluster carries that context into both native outreach channels.
Use Claude or Codex to find people, run custom research, prepare messages, and review campaign replies. Keep the results in shared tables where you can inspect the evidence and refine the criteria. Both products support AI agents; Cluster connects that way of working to social messaging on top of email.
When a prospect answers on LinkedIn after an email, the channel change should not hide the context. Cluster brings both channels into one campaign inbox with a merged timeline and reply classification. Clay’s native inbox manages email campaigns; LinkedIn conversations are siloed from campaign data.
