Newsletter monetization — paid subscriptions, sponsorships, ad sales, paid recommendations, premium tiers, pricing strategy, subscriber-to-revenue conversion. Use when your newsletter isn't generating revenue, paid subscribers aren't converting, can't find sponsors, unsure how to price a premium tier, or torn between ad-supported and subscription models. Do NOT use for sending email campaigns (use /sales-email-marketing), growing your subscriber list (use /sales-audience-growth), or platform-specific setup (use /sales-kit, /sales-mailchimp, etc.).

Help the user monetize their newsletter — paid subscriptions, sponsorships, ad sales, paid recommendations, premium content tiers, and pricing strategy. This skill is tool-agnostic but includes platform-specific guidance.
If references/learnings.md exists, read it first for accumulated knowledge.
Ask the user:
What's your current newsletter situation?
What monetization model interests you?

Paid subscriptions:
Subscribers × conversion rate × monthly price × 12 = annual revenue
Example: 5,000 × 5% × $10/mo × 12 = $30,000/yr
Sponsorships:
Issues/month × opens per issue × CPM / 1000 × 12 = annual revenue
Example: 4/mo × 4,500 opens × $50 CPM / 1000 × 12 = $10,800/yr
Paid recommendations:
New subscribers/month × recommendation conversion × payout × 12
Example: 500/mo × 30% × $2 × 12 = $3,600/yr
Don't paywall your growth engine — if your best content is behind a paywall, you lose word-of-mouth growth. Keep your core insight free; paywall the depth, data, and community.
Sponsorship CPM varies wildly by niche — B2B/finance newsletters command $50–$100+ CPM; general interest may get $10–$25. Don't assume average CPM applies to your niche.
Platform fees add up — Substack takes 10%, Kit takes 0.6% + Stripe ~2.9%. At scale, the difference is thousands of dollars. Factor platform fees into your pricing.
Paid recommendations can hurt trust — recommending low-quality newsletters for money erodes subscriber trust. Vet every recommendation as if you're personally endorsing it.
Annual plans reduce churn significantly — monthly subscribers churn at 5–8%/mo; annual subscribers effectively churn at 1–2%/mo. Push annual plans with meaningful discounts.
references/learnings.md with today's date.This skill covers a strategy domain across many platforms. Before pointing the user to any specific platform skill (any /sales-{platform} listed in ## Related skills, e.g., /sales-mailshake, /sales-klaviyo, /sales-apollo), read that platform skill's actual SKILL.md first. The 1-line description in ## Related skills is enough to identify a candidate — it's not enough to commit to it or to write a prompt that invokes it well.
How to read it:
~/.claude/skills/{skill-name}/SKILL.md exists locally, Read it.sales-* skills, WebFetch directly from this repo: https://raw.githubusercontent.com/sales-skills/sales/main/skills/{skill-name}/SKILL.md — e.g., for sales-mailshake: https://raw.githubusercontent.com/sales-skills/sales/main/skills/sales-mailshake/SKILL.md.sales-* skills (third-party), look up {org}/{repo} in ~/.claude/skills/sales-do/references/skill-sources.md if installed and fetch the same skills/{skill-name}/SKILL.md path under that repo.After reading, ground your recommendation in something concrete from the SKILL.md (its scope, a sub-flow, its argument-hint shape, or a "Do NOT use for..." negative trigger). Align any generated invocation with the platform skill's argument-hint. If the platform skill turns out not to fit the user's situation, swap to another or handle the question here directly rather than recommending a poor fit.

Install: npx skills add sales-skills/sales --skill sales-doUser says: "I have 3,000 newsletter subscribers and want to start making money from it" Skill does: Assesses niche and engagement, recommends starting with paid recommendations (low effort, immediate revenue) + sponsorships (higher revenue), provides rate card template and recommendation setup steps Result: User launches with 2 revenue streams and a clear path to paid subscriptions at 5K+ subscribers
User says: "I want to launch a $10/month paid tier for my finance newsletter" Skill does: Helps define free vs paid content split, recommends founding member pricing, creates launch timeline with pre-launch content backlog, suggests annual pricing at $100/yr Result: User has a launch plan with pricing, content strategy, and promotion sequence
User says: "How much should I charge for newsletter sponsorships? I have 8,000 subscribers with 42% open rate" Skill does: Calculates 3,360 opens per issue, applies niche-appropriate CPM, recommends starting rate of $150–$250/issue, provides rate card template with package deals Result: User has a defensible sponsorship rate with a professional media kit outline
Symptom: Launched paid tier but conversion is under 1% Cause: Paid value prop isn't differentiated enough from free, or audience hasn't been warmed up Solution: Survey free subscribers on what they'd pay for. Tease premium content in free issues for 2–4 weeks before pushing the upgrade. Consider a free trial period.
Symptom: Sponsors buy one issue but don't come back Cause: Click-through rates are low, or no post-campaign reporting provided Solution: Send sponsors a performance report after each placement (opens, clicks, CTR). Offer A/B testing on ad copy. Ask for feedback on what would make them renew.
Symptom: Newsletter revenue hasn't grown in months despite growing subscriber count Cause: Single revenue stream maxed out, or pricing hasn't been updated Solution: Add a second revenue stream (if only sponsorships, add paid tier; if only subscriptions, add recommendations). Raise prices 10–20% — most newsletters underprice. Launch an annual plan if only offering monthly.
