What it does
Send Cold Email is an agent skill from Othmane-Khadri/YALC-the-GTM-operating-system. Send a cold email campaign or single message via the configured email provider (Instantly by default), optionally pre-drafting the sequence. Use when the user says 'send a cold email to this list', 'fire the email sequence', 'launch the email campaign', 'send the drip sequence', or 'email these qualified leads'. Side-effecting — calls Instantly API and writes to local SQLite + Notion.
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/example-output.md`).
It sits in Sales & Support, covering Cold outreach and Email marketing. It works with SQLite, Notion and LinkedIn. The repository describes itself as: YALC 1.0, the open-source Clay alternative. MIT, CLI-first, self-hosted, runs in Claude Code. Yalc today is an intelligent orchestration layer that runs pre configured GTM agents…. The licence is MIT.
When your agent uses it
- The user says send a cold email to this list
- Fire the email sequence
- Launch the email campaign
- Send the drip sequence
Example prompts
- “send a cold email to this list”
- “fire the email sequence”
- “launch the email campaign”
- “/send-cold-email”
Requirements
- Node.js
- A credential in INSTANTLY_API_KEY
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 5686d1f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
INSTANTLY_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Send Cold Email loads about 515 tokens when it runs, and up to ~693 if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 193 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Send Cold Email
I'll wrap two CLIs — email:create-sequence (drafts the sequence) and email:send (fires it). Both side-effecting → both shell-out.
When This Skill Applies
- "send a cold email to this list"
- "fire the email sequence"
- "launch the email campaign"
- "send the drip sequence"
- "email these qualified leads"
NOT this skill (use launch-linkedin-campaign instead):
- "launch a LinkedIn campaign" — that's the connect+DM flow on LinkedIn.
NOT this skill (use personalize-message instead):
- "personalize a single email" — single per-lead variant, not bulk send.
Workflow
Step 0 — Ask for inputs
"Which result set, what subject + intro, how many touches?"
Step 1 — Validate (result set exists, intro non-empty)
Step 2 — Shell out to email:create-sequence
npx tsx src/cli/index.ts email:create-sequence --result-set <id> --subject "<subject>" --intro "<intro>"(Verify exact flags via --help.)
Step 3 — Render the drafted sequence + ask for approval
"Drafted N messages across M touches. Send? (yes / preview only / cancel)"
Step 4 — On yes, shell out to email:send
npx tsx src/cli/index.ts email:send --sequence-id <id>Step 5 — Render send result + offer follow-ups
"Want me to (a) track replies via
track-campaigns, (b) personalize follow-ups for hot replies?"
Notes
- Requires
INSTANTLY_API_KEY(or whatever email provider is configured). - Default cadence: day 0, day 3, day 7, day 14.
- The CLI enforces sending limits per the user's email accounts (Instantly handles deliverability).
