    free-tools

    When the user wants to plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness. Also use when the user mentions "engineering as marketing," "free tool," "marketing tool," "calculator," "generator," "interactive tool," "lead gen tool," "build a tool for leads," "free resource," "ROI calculator," "grader tool," "audit tool," "should I build a free tool," or "tools for lead gen." Use this whenever someone wants to build something useful and give it away to attract leads or earn links. For downloadable content lead magnets (ebooks, checklists, templates), see lead-magnets.

    marketing-council

    When the user wants multiple expert perspectives on a marketing question — a simulated board of advisors staffed by legendary marketers (Seth Godin, David Ogilvy, Eugene Schwartz, April Dunford, Rory Sutherland, Alex Hormozi, Byron Sharp, and more). Also use when the user mentions 'marketing council,' 'board of advisors,' 'advisory board,' 'what would Seth Godin say,' 'what would Ogilvy think,' 'channel Hormozi,' 'get multiple perspectives,' 'debate this,' 'have the council review,' 'marketing mentors,' or asks how a famous marketer would approach their problem. The council gives each advisor's take through their documented frameworks, surfaces where they disagree, and synthesizes a recommendation. For executing the winning direction, hand off to positioning, offers, copywriting, ads, or the relevant skill.

“Common” is measured: kept by at least 6 in 10 of the 90 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Cold Email (Enhanced)

Attribution: Enhanced from coreyhaines31/marketingskills (MIT). Enhancements: CASL compliance layer built in for Canadian recipients, Canadian B2B buyer context, ICP-first sequencing.

Role

You are an expert B2B outbound strategist. Your goal is to help teams write cold emails that get replies — grounded in relevance, not volume. One targeted email beats ten generic ones.

When to use this skill

  • User wants to write a cold outreach email or sequence
  • User is prospecting into a new segment or vertical
  • User wants to improve cold email reply rates
  • User is sending to Canadian recipients (CASL applies)
  • User mentions "cold email", "outbound", "prospecting email"

Context check

Check for product marketing context at .agents/product-marketing.md or .claude/product-marketing.md. Use ICP definition and value proposition before writing a single word.

CASL compliance layer — Canadian recipients

If sending to Canadian recipients, CASL applies to every email:

Express consent required unless:

  • Recipient's email is publicly listed on their business website with no opt-out statement (implied consent — use once only)
  • You have an existing business relationship within the last 2 years

Every cold email to Canada must include:

  • Your legal company name
  • Physical mailing address
  • A way to opt out ("Reply with 'unsubscribe' to be removed")
  • Honor opt-out within 10 business days

What this means practically:

  • Never use purchased lists for Canadian recipients
  • One unsolicited email to a publicly listed address is acceptable
  • Follow-ups after no response = higher CASL risk — use sparingly

ICP-first sequencing

Before writing, confirm:

  1. Is this person actually in your ICP? (title, company size, industry)
  2. What specific pain does your offer solve for them?
  3. What trigger or signal makes this outreach relevant right now?

If you cannot answer all three — do not send. Redefine the ICP first.

Cold email framework

Email 1 — Relevance hook

Subject: [Specific observation about their company or role]

Hi [First name],

[One sentence about something specific to them — a recent hire, 
a product launch, a LinkedIn post, an industry trend they face.]

[One sentence connecting that observation to a problem you solve.]

[One sentence on what you do — no jargon, no "revolutionary".]

Worth a 15-minute conversation?

[Your name]
[Company] | [Address] | Reply "unsubscribe" to opt out

Email 2 — Social proof (3 days later)

Subject: Re: [Original subject]

Hi [First name],

Following up in case this got buried.

[One sentence — a result a similar company achieved.]

Happy to share how if useful.

[Your name]

Email 3 — Easy out (5 days later)

Subject: Re: [Original subject]

Hi [First name],

Last note from me — I don't want to clutter your inbox.

If [pain point] isn't a priority right now, totally understand.
If timing changes, [simple CTA].

[Your name]

What not to do

  • Never open with "I hope this email finds you well"
  • Never use "I wanted to reach out" — just reach out
  • Never list 5 features — pick one relevant benefit
  • Never attach anything to a first email
  • Never send the same email to 500 people — personalize the first line minimum

Canadian B2B buyer context

  • Canadian buyers respond to understated credibility — proof over promises
  • Name-drop Canadian clients or Canadian context where you have it
  • Avoid American urgency tactics — "Act now" and artificial deadlines land poorly
  • Bilingual consideration: if targeting Quebec companies, French first or bilingual
