SET IT TO YOUR MOTION

This was built for a B2B operator growing a topic-focused newsletter tied to a business. Set these to your stack:

03 / THE FULL SKILL

Everything the skill does, in full.

── WHAT THIS DOES

Takes a newsletter and builds the system to grow it: the offer that convinces someone to hand over an email, the loops that turn readers into more readers, the publishing rhythm that keeps opens high, and the metrics that tell you whether the audience is actually engaged or just large. It builds the growth plan. It does not write every issue for you.

── THE METHOD
  1. 1
    The subscribe offer (earn the email)

    An email address is a real ask. The subscribe offer is the promise that makes it worth it: a specific, recurring value the reader cannot get by scrolling. "Sign up for updates" earns nothing. "Every week, one teardown of how a real team does X" earns the click. Optionally pair it with a lead magnet, but the durable offer is the promise of every issue, not a one-time download.

  2. 2
    Growth loops (compounding, not just paid)

    One-time pushes plateau. Loops compound. Build the loops that fit the topic: a referral mechanic (readers invite readers for a reward), shareable issues (a format people forward), cross-promotions with adjacent newsletters, and a public archive that pulls search traffic. Name the two or three loops worth building, because a loop beats a blast every time.

  3. 3
    Content rhythm (keep them opening)

    Consistency is the retention engine. Set a cadence you can actually hold and a recognizable structure so readers know what they are getting. The issue people open every week is worth more than the perfect issue that shows up randomly. Define the recurring format so writing gets easier and opens stay high.

  4. 4
    Activation (the first two weeks decide)

    Most unsubscribes happen right after signup, when the promise and the reality first meet. Plan the welcome sequence and the first few issues to deliver the offer immediately, so a new subscriber gets the value they were promised before they forget why they signed up. Acquisition without activation is a leaky bucket.

  5. 5
    Metrics that matter (not list size)

    List size is a vanity number. A big, dead list is worse than a small, engaged one. Track the NORTH_STAR of engaged subscribers (opens and clicks over time), net growth (subscribes minus unsubscribes), the growth-loop contribution (how many came from readers, not spend), and, where the CRM allows, pipeline touched. The skill flags when someone is optimizing for a number that does not pay.

── QUALITY GATES
  • The subscribe offer is a specific recurring promise, not "get updates."
  • At least one compounding growth loop is in the plan, not only paid or one-time pushes.
  • Activation (welcome plus first issues) is planned, not just acquisition.
  • The headline metric is engagement, not raw list size, and the skill says so out loud.
  • Any rate or count shown is labeled illustrative unless it came from your connected data.
── OUTPUT (EXAMPLE)
EXAMPLE OUTPUT
NEWSLETTER GROWTH PLAN · weekly teardown newsletter (illustrative)
Topic: one real team's workflow, taken apart, every Thursday.

Subscribe offer: "Every Thursday, one teardown you can copy by Friday."
  (plus optional lead magnet: a starter pack of the 5 best past teardowns)

Growth loops:
  1. Referral: invite 3, unlock the private archive
  2. Shareable format: each issue ends with a copy-paste checklist people forward
  3. Cross-promo: swap mentions with 2 adjacent newsletters each month

Rhythm: same 3-part structure weekly (the setup, the teardown, the steal).

Activation: 1 welcome + best-of issue within 24h, so the promise lands before they forget.

Metrics (north star = engaged subs):
  Engaged (opened 2 of last 4)   track weekly
  Net growth (subs - unsubs)      not gross signups
  % from loops vs paid            is growth compounding?
  Pipeline touched (via CRM)      business impact, not applause

Next move: connect the email tool so the plan targets your real bottleneck, not a generic one.

CLAUDE
Offer, loops, and the metric that actually matters. Subscribe offer: "Every Thursday, one teardown you can copy by Friday." Growth loops: 1. Referral: invite 3, unlock the private archive 2. Shareable format: each issue ends with a copy-paste checklist Metrics (north star = engaged subs): Engaged (opened 2 of last 4) track weekly The catch worth naming: I flagged list size as the metric to ignore, not the one to chase. A newsletter can grow the raw number every week and still be dying underneath if opens are dropping, engaged subscribers is the number that tells you the truth. One sharpener: connect your email tool so opens and unsubscribes are real, right now the plan is built on your rough estimate of where you stand.
04 / GO FURTHER

Where an operator takes this next.

The plan is step one. Here is where an operator takes it once the manual version proves out.

You built the system once, now the metrics that matter get watched every week.

01
Watch the real numbers, not the guess

Connect your email tool (a newsletter platform) so opens, clicks, and unsubscribes feed the plan weekly instead of a one-time estimate.

02
Catch the leak before it compounds

Wire a scheduled Claude task to flag the week engaged-subscriber rate drops two weeks running, so activation problems get caught before they show up in a shrinking list.

03
Tie growth to pipeline

Sync subscriber emails against Salesforce or HubSpot so the plan can report how many touched pipeline, not just how many opened.
