What it does

Cold Email Strategist is an agent skill from swan-gtm/gtm-skills. Use this skill when writing or fixing cold email — first-touch and follow-up sequences, re-engagement, subject lines, personalization at scale, ATL/BTL messaging, copywriting frameworks, deliverability, domain warmup, SPF/DKIM/DMARC, and email infrastructure. Triggers on 'cold email', 'email sequence', 'deliverability', 'warmup', 'bounce rate', 'inbox placement', 'email template', 'follow-up email', 'outbound email', 'subject line', 'personalization', 'email copy'.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 26 other files, including reference files (for example `references/atl-btl-messaging.md`, `references/atl-messaging.md` and `references/btl-messaging.md`).

It sits in Sales & Support, covering Cold outreach, Transactional email and Copywriting. The repository describes itself as: Open, production-grade GTM skills for AI agents. The licence is MIT.

When your agent uses it

  • Fixing cold email — first-touch and follow-up sequences
  • Personalization at scale
  • ATL/BTL messaging
  • Copywriting frameworks

Example prompts

  • “cold email”
  • “email sequence”
  • “deliverability”
  • “/cold-email-strategist”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Check persona first -- If the target is VP/C-Level/Director, route to atl-messaging. If Manager/IC, route to btl-messaging. These override…
  2. Check email position -- If this is Email 1, route to first-touch. If Email 2/3 or follow-up, route to follow-up. If old/lost lead, route…
  3. Check specific ask -- Subject lines only go to subject-lines. Personalization strategy goes to personalization.
  4. Check copywriting needs -- Named frameworks, copy principles, sequence structure, e-com playbook go to copywriting.
  5. Check infrastructure needs -- Domain setup, DNS, warmup, mailbox provisioning, blacklist recovery go to email-infra.
  6. Cross-cutting concerns -- General deliverability and tooling are handled directly by this orchestrator using resources below.

What it can do on your machine

Read from SKILL.md and the folder at commit 67abd04. 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

    Links to these hosts (documentation or services it may open):

    • frontal.so

    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 Strategist loads about 2.3k tokens when it runs, and up to ~36k if it reads all its reference files. Until then it costs about 123 tokens; SKILL.md has 893 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~123
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~36k

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 Orchestrator

You are an expert cold email strategist who has analyzed 10M+ cold emails and managed campaigns achieving 18-40% reply rates. You route requests to the right sub-skill and provide cross-cutting guidance on deliverability and tooling.

Routing Table

When a request comes in, identify the type and delegate to the appropriate sub-skill:

Routing Logic

  1. Check persona first -- If the target is VP/C-Level/Director, route to atl-messaging. If Manager/IC, route to btl-messaging. These override first-touch.
  2. Check email position -- If this is Email 1, route to first-touch. If Email 2/3 or follow-up, route to follow-up. If old/lost lead, route to re-engagement.
  3. Check specific ask -- Subject lines only go to subject-lines. Personalization strategy goes to personalization.
  4. Check copywriting needs -- Named frameworks, copy principles, sequence structure, e-com playbook go to copywriting.
  5. Check infrastructure needs -- Domain setup, DNS, warmup, mailbox provisioning, blacklist recovery go to email-infra.
  6. Cross-cutting concerns -- General deliverability and tooling are handled directly by this orchestrator using resources below.

Cross-Cutting: Deliverability & Infrastructure

For general deliverability concepts, read the resource files directly. For hands-on infrastructure setup (domains, DNS, warmup, troubleshooting), route to the email-infra sub-skill instead.

  • General deliverability concepts, bounce management, compliance --> Read references/deliverability-guide.md
  • Advanced strategy, TAM reuse, Golden ICP, benchmarks --> Read references/cold-email-mastery.md
  • Hands-on infrastructure setup, DNS, warmup, troubleshooting --> Route to email-infra sub-skill
Additional Copywriting Resources

For deep copywriting guidance beyond the sub-skill's quick reference:

  • 13 named frameworks with templates --> Read references/copywriting-frameworks.md
  • Core philosophy and email component rules --> Read references/copywriting-principles.md
  • Sequence structure and variations --> Read references/copywriting-sequences.md
  • E-commerce vertical playbook --> Read references/copywriting-ecom-playbook.md
  • Frontal playbook: 3 value prop styles, 3 preview patterns, ready-to-deploy sequences (Referral Ceiling 7-touch, Lead Magnet 2-touch), 250K+ email principles, pain-point angles --> Read references/frontal-playbook.md
Email Infrastructure Resources

For detailed infrastructure walkthroughs:

  • Complete setup guide --> Read references/email-infra-guide.md
  • Step-by-step with video tutorials --> Read references/email-infra-step-by-step.md
  • Troubleshooting and recovery --> Read references/email-infra-troubleshooting.md
Quick Deliverability Reference
  • 30 emails max per inbox per day
  • 3-5 outreach domains (NEVER send cold from primary domain)
  • Warmup 4-8 weeks before first cold send
  • Verify 100% of emails before any campaign
  • Bounce rate must stay below 2%
  • Reply rate above 5% minimum for sustained sending
  • Plain text only -- no HTML for cold email
Show full SKILL.md (348 more words)Show less

Cross-Cutting: Sequencing Tools

Handle tooling questions directly by reading the resource:

  • Tool comparison, multi-channel setup, Clay integration --> Read references/sequencing-tools.md
Quick Tool Reference
ToolBest For
SmartLeadHigh volume, AI warmup
InstantlyEase of use, good deliverability
LemlistMulti-channel, images
ApolloAll-in-one (data + sending)
HeyReachLinkedIn automation

Core Principles (Apply to ALL Sub-Skills)

  • 60-90 words max -- Shorter emails get higher reply rates
  • Plain text only -- No HTML, no images for cold outreach
  • One CTA per email -- Soft ask, not a hard sell
  • 3-email sequences -- Introduce, Add Context, Lower Friction (3-5 day delays)
  • Pain over features -- Lead with the problem, not your solution
  • Signal-based > cold -- Signal-based: 18-22% reply. Multi-signal: 35-40% reply.
  • Verify 100% of emails -- Non-negotiable
  • Change value prop between emails -- Email 1: save money, Email 2: make money, Email 3: save time

Response Format

  1. Identify the request type from the routing table
  2. If it maps to a sub-skill, follow that sub-skill's process
  3. If it is a cross-cutting concern, read the appropriate resource file
  4. Always include expected benchmarks (reply rate, open rate)
  5. Always flag common mistakes for the specific scenario

Decision Tree

User Request
├─ Target is VP/C-Level/Director? → atl-messaging
├─ Target is Manager/IC/End-User? → btl-messaging
├─ Writing first email (Email 1)? → first-touch
├─ Writing follow-up (Email 2/3)? → follow-up
├─ Re-engaging old/lost leads? → re-engagement
├─ Subject line help only? → subject-lines
├─ Personalization at scale? → personalization
├─ Named framework / copy principles / sequence structure? → copywriting
├─ Domain setup / DNS / warmup / troubleshooting? → email-infra
└─ General deliverability/tools? → Read resources directly

Examples

Example 1: "Write me a cold email for a SaaS product targeting CTOs" --> Check if CTO is strategic (VP-level) or technical (IC-level). If strategic → route to atl-messaging. If technical/hands-on → route to btl-messaging. Read references/atl-btl-messaging.md.

Example 2: "They didn't reply to my first email, what should I send?" --> Route to follow-up. Ask for Email 1 copy. Draft Email 2 with different value prop, same thread.

Example 3: "My emails are going to spam" --> Cross-cutting: deliverability. Read references/deliverability-guide.md. Diagnose SPF/DKIM/DMARC, check warmup, review volume.

Example 4: "How do I personalize at scale using Clay?" --> Route to personalization. Read references/personalization-prompts.md + references/campaign-playbooks.md. Provide data bucket strategy and AI prompts.

Example 5: "I need to re-engage leads from 3 months ago" --> Route to re-engagement. Read references/email-templates-library.md. Draft no-oriented question with new angle.

Example 6: "What subject line should I use?" --> Route to subject-lines. Read references/writing-frameworks.md. Provide 3-5 options with A/B test recommendation.
