What it does

Email And Newsletter is an agent skill from social-media-skills/skills. Email and newsletter strategy for creators and brands — the owned-audience layer that social feeds. Use when someone wants to "start/grow a newsletter," "build an email list," "turn followers into subscribers," "should I use Substack/beehiiv/LinkedIn," "repurpose my newsletter into social (or vice versa)," or build the audience layer social can't take away. Runs email (habit) + a web archive (discovery) off the same work and loops content social<-email. Uses the INBOX framework. Reads brand-profile +…

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `evals/evals.json`, `references/editions-and-repurposing.md` and `references/newsletter-2026-reality.md`).

It sits in Writing & Content, covering Newsletters, Content repurposing and Email management. It works with LinkedIn, Substack and Google Analytics. The repository describes itself as: 106 social media skills for AI agents - strategy, writing, video, design, platform growth, publishing, and analytics. Works with Claude, Cursor, OpenClaw, Hermes & 40+ agents. The licence is MIT.

When your agent uses it

  • Someone wants to start/grow a newsletter
  • Build an email list
  • Turn followers into subscribers
  • Should I use Substack/beehiiv/LinkedIn

Example prompts

  • “start/grow a newsletter,”
  • “build an email list,”
  • “turn followers into subscribers,”
  • “/email-and-newsletter”

Workflow steps

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

  1. brand-profile — positioning/offer.
  2. voice-builder — the personality that is the moat.
  3. content-pillars — the one problem/topic the newsletter owns.

What it can do on your machine

Read from SKILL.md and the folder at commit 6e30eeb. 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

Email And Newsletter loads about 1.5k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 232 tokens; SKILL.md has 549 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~232
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.5k

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.

email-and-newsletter

The owned channel — the newsletter is the audience layer social can't take away, plus the email↔social loop. The agent strategizes + drafts; the ESP is external + human-run; scheduling-and-queue → WoopSocial publishes the social side (signup-driving + repurposed posts).

The POV: own the audience, run two surfaces

Every platform rents you attention and can change the rules overnight; a newsletter is the one audience layer you own — opt-in, deliverable, measurable, the highest-ROI channel and the thing that makes everything else compound. "Owned" runs on two surfaces off the same work: email builds the habit and relationship; the web archive (Substack/LinkedIn/published) compounds discovery through search, social, and AI answer engines. Win on niche + personality (one problem, one reader), treat deliverability as behavioral (clicks/replies, not opens), and win edition 2 (weeks 2–3 is where subscribers churn).

Read these first

  1. brand-profile — positioning/offer.
  2. voice-builder — the personality that is the moat.
  3. content-pillars — the one problem/topic the newsletter owns.

The framework: INBOX

(Depth: references/the-inbox-framework.md.)

  • I — Identify the one problem/audience: one problem for one reader; personality is the moat.
  • N — Nurture an owned list: capture from social (the link-in-bio-and-traffic handoff) — simple form + lead magnet; own your domain/list; welcome sequence + a high-value edition 2.
  • B — Build habit + discovery on two surfaces: email = habit; web archive = discovery (search + AI engines); same work, adapted per surface; pick the platform by goal.
  • O — Offer value (70-20-10): 70% value / 20% personal / 10% promo; short subject; scannable, mobile- first; interactive; reply to replies.
  • X — eXpand via the social↔email loop: one edition → a week of social; best social → next edition; measure clicks/replies/signups from the ESP (not opens).

The reality (verify-quarterly)

Owned-audience ROI; email-habit + web-discovery (+ AI engines); behavioral deliverability (clicks/replies

opens; SPF/DKIM/DMARC, list hygiene, cadence); niche + personality; capture + 70-20-10 + retention (weeks 2–3); platforms (beehiiv/Substack/LinkedIn/Kit — own your domain/list); honest monetization; the social↔email loop: references/newsletter-2026-reality.md. Edition structure, welcome sequence, repurposing engine, platform cheat-sheet + worked examples: references/editions-and-repurposing.md.

Honest scope (never violate)

  • WoopSocial does not send email (no ESP/list/capture/open tracking). Sending happens in an external ESP, human-set-up. The agent strategizes + drafts editions + social-promo; WoopSocial publishes the social posts that grow the list + repurpose the newsletter.
  • Metrics from the ESP + GA4 (clicks/replies/signups, not opens-as-vanity); never fabricate.
  • Consent mandatory — opt-in, visible unsubscribe, sender identity (CAN-SPAM/GDPR). No bought lists / no-consent sends / misleading subjects / spam. Monetize honestly. (Scope, distinctions + connections: references/scope-and-connections.md.)

Distinct from its siblings (route correctly)

email-and-newsletter (this) = the owned email channel + the email↔social loop · link-in-bio-and-traffic = the capture/handoff that drives signups in · cross-platform-repurposing = same-moment multi-platform · content-recycling = evergreen reuse over time · lead-magnets-and-funnels = the magnet design · social-selling-and-dm = the DM funnel.

Where this connects

Reads first: brand-profile, voice-builder, content-pillars. Fed by: link-in-bio-and-traffic (signups), analytics-and-reporting (best social → next edition; ESP/GA4 readout), lead-magnets-and-funnels. Repurpose engine: cross-platform-repurposing, content-recycling, reels-script/ai-video, carousel-writer, caption-writer/hook-writer, linkedin-post-writer. Discovery: ai-search-optimization/social-seo, linkedin-growth. Publish (social side): scheduling-and-queue → WoopSocial; measure/test: analytics-and-reporting, goals-and-kpis, experimentation (A/B subjects).

Definition of done

A focused niche (one problem/one reader) in the brand voice; an owned list grown via social capture (simple form + lead magnet, own domain/list) with a welcome sequence + high-value edition 2; both surfaces run off the same work (email habit + SEO/GEO-optimized web archive); editions at 70-20-10 with short subjects, scannable + interactive; the social↔email loop running both ways; metrics taken from the ESP + GA4 (clicks/replies/signups, not opens, nothing fabricated) with consent + unsubscribe; WoopSocial publishes only the social side (email send stays external); correctly distinguished from link-in-bio-and-traffic, cross-platform-repurposing, content-recycling, and lead-magnets-and-funnels.
