What it does

Suede Cold Email is an agent skill from JasonColapietro/suede-creator-skills. Suede-owned B2B cold-email discipline for evidence-based personalization, subject lines, opening lines, concise bodies, one clear CTA, and bounded follow-up sequences. Use when writing or repairing outbound email to qualified prospects. NOT FOR: building or qualifying the prospect list (use suede-prospecting), lifecycle or nurture email (use suede-emails), or broader sales collateral (use suede-sales-enablement).

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `CARD.md`, `agents/openai.yaml` and `evals/evals.json`).

It sits in Sales & Support, covering Cold outreach and Sales enablement. The repository describes itself as: Open-source AI skills for SEO, AI search visibility, conversion copy, marketing strategy, and business operations. Reusable workflows for Claude Code and Codex, plus code review… The licence is MIT.

When your agent uses it

  • Repairing outbound email to qualified prospects
  • Tasks that involve Cold outreach
  • Tasks that involve Sales enablement

Example prompts

  • “/suede-cold-email”

Workflow steps

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

  1. Who are you writing to? Role, company, why them specifically
  2. What do you want? The outcome (meeting, reply, intro, demo)
  3. What's the value? The specific problem you solve for people like them
  4. What's your proof? A result, case study, or credibility signal
  5. Any research signals? Funding, hiring, LinkedIn posts, company news, tech stack changes

What it can do on your machine

Read from SKILL.md and the folder at commit e5f94d7. 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

Suede Cold Email loads about 2.2k tokens when it runs, and up to ~7.8k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 1,115 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.8k

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.

Suede Cold Email Writing

Use this Suede cold-email playbook to write concise, evidence-grounded outreach that sounds human and respects the recipient.

Before Writing

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Understand the situation (ask if not provided):

  1. Who are you writing to? Role, company, why them specifically
  2. What do you want? The outcome (meeting, reply, intro, demo)
  3. What's the value? The specific problem you solve for people like them
  4. What's your proof? A result, case study, or credibility signal
  5. Any research signals? Funding, hiring, LinkedIn posts, company news, tech stack changes

Work with whatever the user gives you. If they have a strong signal and a clear value prop, that's enough to write. Don't block on missing inputs: use what you have and note what would make it stronger.


Writing Principles

Write like a peer, not a vendor

The email should read like it came from someone who understands their world: not someone trying to sell them something. Use contractions. Read it aloud. If it sounds like marketing copy, rewrite it.

Every sentence must earn its place

Cold email is ruthlessly short. If a sentence doesn't move the reader toward replying, cut it. The best cold emails feel like they could have been shorter, not longer.

Personalization must connect to the problem

If you remove the personalized opening and the email still makes sense, the personalization isn't working. The observation should naturally lead into why you're reaching out.

See personalization.md for the 4-level system and research signals.

Lead with their world, not yours

The reader should see their own situation reflected back. "You/your" should dominate over "I/we." Don't open with who you are or what your company does.

One ask, low friction

Interest-based CTAs ("Worth exploring?" / "Would this be useful?") beat meeting requests. One CTA per email. Make it easy to say yes with a one-line reply.


Voice & Tone

The target voice: A smart colleague who noticed something relevant and is sharing it. Conversational but not sloppy. Confident but not pushy.

Calibrate to the audience:

  • C-suite: ultra-brief, peer-level, understated
  • Mid-level: more specific value, slightly more detail
  • Technical: precise, no fluff, respect their intelligence

What it should NOT sound like:

  • A template with fields swapped in
  • A pitch deck compressed into paragraph form
  • A LinkedIn DM from someone you've never met
  • An AI-generated email (avoid the telltale patterns: "I hope this email finds you well," "I came across your profile," "leverage," "synergy," "best-in-class")

Structure

There's no single right structure. Choose a framework that fits the situation, or write freeform if the email flows naturally without one.

Common shapes that work:

  • Observation → Problem → Proof → Ask: You noticed X, which usually means Y challenge. We helped Z with that. Interested?
  • Question → Value → Ask: Struggling with X? We do Y. Company Z saw [result]. Worth a look?
  • Trigger → Insight → Ask: Congrats on X. That usually creates Y challenge. We've helped similar companies with that. Curious?
  • Story → Bridge → Ask: [Similar company] had [problem]. They [solved it this way]. Relevant to you?

For the full catalog of frameworks with examples, see frameworks.md.


Subject Lines

Short, boring, internal-looking. The subject line's only job is to get the email opened: not to sell.

  • 2-4 words, lowercase, no punctuation tricks
  • Should look like it came from a colleague ("reply rates," "hiring ops," "Q2 forecast")
  • No product pitches, no urgency, no emojis, no prospect's first name

See subject-lines.md for the full data.


Follow-Up Sequences

Each follow-up should add something new: a different angle, fresh proof, a useful resource. "Just checking in" gives the reader no reason to respond.

  • 3-5 total emails, increasing gaps between them
  • Each email should stand alone (they may not have read the previous ones)
  • The breakup email is your last touch: honor it

See follow-up-sequences.md for cadence, angle rotation, and breakup email templates.

Quality Check

Run this pass on the draft before presenting it. Every item resolves to something you can observe in the text, not a feeling about it.

  • "You/your" outnumbers "I/we" in the body
  • Deleting the personalization sentence breaks the sentence that follows it
  • Exactly one ask, answerable with a one-line reply
  • Body is under 75 words
  • Zero strings from What to Avoid appear in the draft: check that list term by term, not by impression
  • Read aloud it uses contractions, and no sentence reads as marketing copy

Any item that fails means rewrite before presenting. Do not hand over a draft with a caveat attached to it.


Output Format

Deliver every email in this shape, with these field labels verbatim.

Subject: [2-4 words, lowercase]

Body: (NN words, target under 75)
[the email exactly as it would be pasted into the send tool]

CTA: [the single ask, quoted from the body]

Personalization source: [the specific signal this email traces to (the post, the filing,
the job ad, the release) with enough detail that the user can confirm it is real]

Personalization source: is required on every email. It is what makes the "do not invent personalization" boundary auditable. If you cannot name a real source, you do not have personalization, and the opening line has to change.

Emit the follow-up table only when the user asked for a sequence rather than a single message:

#Send dayNew angle it carriesSubject
10......
2+3......

3-5 emails total: see follow-up-sequences.md for cadence and angle rotation. Omit the table entirely for a single-message request.


What to Avoid

  • Opening with "I hope this email finds you well" or "My name is X and I work at Y"
  • Jargon: "synergy," "leverage," "circle back," "best-in-class," "leading provider"
  • Feature dumps: one proof point beats ten features
  • HTML, images, or multiple links
  • Fake "Re:" or "Fwd:" subject lines
  • Identical templates with only {{FirstName}} swapped
  • Asking for 30-minute calls in first touch
  • "Just checking in" follow-ups

Data & Benchmarks

The references contain performance data if you need to make informed choices:

Use this data to inform your writing: not as a checklist to satisfy.


Boundaries

  • Do not invent personalization, mutual connections, customer facts, results, urgency, or prior contact.
  • Do not scrape prohibited data, expose sensitive personal information, or advise evasion of consent, spam, or platform rules.
  • Do not send, schedule, enroll, or follow up with anyone without explicit authorization for the exact recipients and sequence.
  • Do not decide that silence means consent; honor opt-outs and suppression lists before any execution.

Routing

  • Need a qualified prospect list -> use suede-prospecting.
  • Need lifecycle or nurture email -> use suede-emails.
  • Need positioning context or collateral -> use suede-product-marketing or suede-sales-enablement.
  • Need CRM stages, lead routing, or suppression operations -> use suede-revops.
  • Before anything goes to a real recipient -> use suede-deslop.
  • From those skills, route cold outbound message and follow-up writing back to suede-cold-email.
