What it does
Cold Email is an agent skill from mohitagw15856/pm-claude-skills. Write a cold sales/B2B outreach email that earns a reply. Use when asked to write a cold email, a sales outreach email, a prospecting email, or a cold email sequence to a business prospect. Produces a short, personalised email — subject, a relevant opener, one clear value-led ask, and a low-friction CTA — plus 2 follow-ups, written to be replied to, not deleted.
Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/reply-rate-calibration.md`).
It sits in Sales & Support, covering Cold outreach. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to write a cold email
- A sales outreach email
- A prospecting email
- A cold email sequence to a business prospect
Example prompts
- “/cold-email”
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cold Email loads about 953 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 483 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.

- cold-email
- description
- Write a cold sales/B2B outreach email that earns a reply. Use when asked to write a cold email, a sales outreach email, a prospecting email, or a cold email sequence to a business prospect. Produces a short, personalised email — subject, a relevant opener, one clear value-led ask, and a low-friction CTA — plus 2 follow-ups, written to be replied to, not deleted.
Cold Email Skill
Cold email works when it's short, clearly about them, and asks for one small thing. Most cold email
fails because it's a feature dump that's all about the sender. This skill writes a tight, personalised
email built on a real trigger or relevance hook, with a single low-friction ask — plus the follow-ups
that actually drive most replies. (For job-search / networking outreach, use outreach-message; this is B2B sales prospecting.)
Not quite this? Use
investor-cold-emailwhen you are writing to investors rather than to prospective customers.
Required Inputs
Ask for these only if they aren't already provided:
- Who you're emailing — role, company, and the segment/ICP.
- The relevance hook — a real reason to contact them now (a trigger event, a specific pain in their role/industry, a mutual connection).
- What you offer — the outcome you drive for people like them (not your feature list).
- Proof — a comparable customer, a result, a number.
- The ask — ideally low-friction (a 15-min call, a relevant resource, an "open to it?" reply).
Output Format
Cold Email: [offer] → [persona]
Subject lines — 3 options, short (≤6 words), specific, no clickbait or "Quick question."
The email (≤120 words):
- Opener — the relevance hook: something true about them (trigger, pain, connection). Not "I hope this finds you well."
- Value — the outcome you drive for people in their seat, with one proof point. One or two sentences.
- Ask — one clear, low-friction request, phrased to make "yes" or even "not now" easy.
- Signature — minimal.
Follow-ups — 2 short ones (send ~3–4 days apart): a value-add nudge (a resource/insight, not "just bumping this") and a graceful breakup email ("I'll close the loop — want me to circle back next quarter?"). Most replies come from these.
Note — what to personalise per prospect (the one line that proves it isn't a blast), and the one metric to watch (reply rate, not open rate).

Deeper Materials
references/reply-rate-calibration.md— line-by-line calibration of what actually moves reply rates, with honest expectations
Quality Checks
- Under ~120 words and skimmable on a phone
- Opens with a real, specific relevance hook about the recipient
- Frames value as the prospect's outcome, with one proof point
- Exactly one low-friction ask
- Includes 2 follow-ups (value-add + graceful breakup)
- Subject is specific and honest (no bait)
Anti-Patterns
- Do not open about yourself ("We're a leading platform…") — lead with them
- Do not feature-dump — one outcome + one proof beats a capability list
- Do not stack asks or ask for too much ("30-min demo" cold) — make the first yes tiny
- Do not use fake personalisation ("loved your post!") — be specifically, verifiably relevant or don't claim it
- Do not skip follow-ups or make them "just checking in" — each must add a reason to reply
Based On
B2B cold-email practice — relevance/trigger-led openers, one-outcome value, single low-friction ask, value-adding follow-up cadence.
Example Trigger Phrases
- "Write a cold email."
- "Write a sales outreach email to this prospect."
- "Write a prospecting email."
- "Draft a cold email sequence for a business prospect."
