Slack validates before Lemlist sends

Claude Skills build the ICP. Clay enriches. Drafts wait in Slack. Nothing hits Lemlist until a human seals it — one Claude environment per client.

The loop

  1. 01Pull client context from Fathom + DriveMeeting notes and files seed the sealed client environment.
  2. 02Claude Skills run market + ICP analysisSkills stay inside that client’s sealed environment. No cross-client bleed.
  3. 03Clay targets and enriches the listBuild the account/contact set from the ICP Skills just wrote.
  4. 04Claude drafts; Slack validatesHumans approve in Slack. Do not launch until Slack says go.
  5. 05Lemlist produce + send, then deliverabilityOnly after validation. Then optimize deliverability on the live campaign.
fr.linkedin.com ↗Skills draft. Slack seals. Lemlist sends.Stopped treating Claude as a chatbot. Encapsulated the agency method as Skills. Claude reads and writes in the stack: Lemlist to produce and send sequences, Clay to target and enrich, Slack for internal validation, Drive + Fathom for client context. Each client has a sealed environment — data never mixes. Workflow: pull context, run market + ICP analysis, enrich, draft, validate in Slack, produce in Lemlist, then optimize deliverability.

The interesting constraint is the hold in Slack, not the Skills pack. Drafts are cheap; a mixed client environment is expensive. Fathom and Drive seed the sealed room with meeting notes and files before anyone writes.

One sealed Claude environment per client keeps market research, ICP, and drafts from leaking across accounts before Lemlist ever sees a row.
