premium skill, $9.99 · outbound-email
Designs the full multi touch sequence between a list and a reply, in the order it has to happen.
Needs an Apify token (usage billed to your Apify account); Node.js 18+. Optional: Instantly v2 or Smartlead API key.
- Apify account and API token (APIFY_TOKEN) (required). Runs the live data actors. Cost: A free Apify account works. Each run bills your own Apify account at the actor's Store price: b2b-buying-signals-hiring-tech-stack-intent-for-clay 0.055 USD per company; clay-to-instantly-smartlead-push 0.01 USD per lead pushed.
- Node.js 18 or newer (required). The MCP tool calls. Cost: Free. It starts the Mamba Labs MCP server with `npx`.
- Instantly v2 or Smartlead API key (optional). Only for the push step; writing the sequence needs no key. Cost: Comes with your existing sending plan. An Instantly v1 key does not work.
unzip cold-email-sequence-system.zip -d ~/.claude/skills/What it does
A sequence is not five emails, it is a system: segmentation, per segment variants, thread strategy, merge variables that survive the sending platform, exit gates, and a breakup that produces replies. This skill encodes the full production build process used across live client campaigns: how to structure touches across days, when a variant earns its own message instead of spintax, how reply data stays readable, and how the copy loads into Instantly or Smartlead without the editor silently rewriting it. Output is a complete, load ready sequence document with word counts and platform correct variables.
