Newsletter Strategy SKILL.md

The Newsletter Strategy skill makes Claude, Codex or another AI agent plan a newsletter readers look forward to. It defines a clear promise, chooses a type, format and cadence, sets a content mix led by reader value, designs an issue template, plans permission-based growth, protects deliverability, handles sponsors and measures clicks, replies, retention and business outcomes rather than opens.

newsletter-strategy/SKILL.md, version 1.0.0, 1,501 words.

A newsletter is one of the few channels a company owns outright. Search rankings shift, social reach falls and ad costs rise, but a list of people who chose to hear from you stays. The best newsletters become something readers look forward to: a clear promise, a consistent format, useful or entertaining content and a voice. Most company newsletters are something else: a monthly roundup of blog links and product updates that readers ignore.

This skill plans and improves newsletters: positioning and promise, audience, format and cadence, content mix, growth, deliverability basics, monetisation or business goals, and measurement. Lifecycle and automated emails sit in the CRM and Lifecycle skills.

Operating principles

  1. A clear promise. Readers should know what they'll get and why it's worth their attention.
  2. Reader value first. Useful insight, curation or entertainment, with company promotion in proportion.
  3. Consistency builds habit. Same day, same format, same voice.
  4. Grow with permission. Clear opt-ins and honest sign-up promises.
  5. Measure engagement that matters. Clicks, replies, retention and business outcomes over vanity opens.

# Newsletter Strategy

A newsletter is one of the few channels a company owns outright. Search rankings shift, social reach falls and ad costs rise, but a list of people who chose to hear from you stays. The best newsletters become something readers look forward to: a clear promise, a consistent format, useful or entertaining content and a voice. Most company newsletters are something else: a monthly roundup of blog links and product updates that readers ignore.

This skill plans and improves newsletters: positioning and promise, audience, format and cadence, content mix, growth, deliverability basics, monetisation or business goals, and measurement. Lifecycle and automated emails sit in the CRM and Lifecycle skills.

## Operating principles
1. **A clear promise.** Readers should know what they'll get and why it's worth their attention.
2. **Reader value first.** Useful insight, curation or entertainment, with company promotion in proportion.
3. **Consistency builds habit.** Same day, same format, same voice.
4. **Grow with permission.** Clear opt-ins and honest sign-up promises.
5. **Measure engagement that matters.** Clicks, replies, retention and business outcomes over vanity opens.

## Newsletter types
| Type | Example | Fits |
|---|---|---|
| Curated roundup with commentary | Five links that matter this week, with our take | Busy professionals in a fast-moving field |
| Single essay | One deep idea per issue | Founders, thought leaders |
| How-to or tactical | One technique with steps and examples | Practitioners |
| Data or research digest | Numbers and trends with analysis | Analysts, decision-makers |
| Product and customer news | Releases, tips, customer stories | Existing customers (often better as lifecycle email) |
| Community | Member highlights, events, discussions | Communities and memberships |

## When to use, and when not to
Use it when launching a newsletter, when open and click rates fall, when list growth stalls, when the newsletter has no clear purpose and when building an owned audience alongside search and social.

Don't use it for automated onboarding, retention and win-back sequences (the CRM and Lifecycle skills) or for deliverability problems in depth (the CRM `email-deliverability` skill).

## Inputs to ask for, in one message
1. Business goals for the newsletter.
2. Audience and what they care about.
3. Current list size, growth sources and engagement data.
4. Past issues and best performers.
5. Email platform and sign-up points.
6. Team capacity and subject matter experts.

## Workflow

### Step 1. Define the promise
One sentence: who it's for, what they get, how often. For example: "Every Tuesday, one practical idea to close your books faster, in five minutes."

### Step 2. Choose type, format and cadence
Match to audience and team capacity; consistency matters more than frequency.

### Step 3. Set the content mix
For example: 80% reader value (insight, how-tos, curation), 20% company (product, events, offers).

### Step 4. Design the template
Recognisable header, short intro, main content, one primary call to action, footer with preferences.

### Step 5. Plan growth
Sign-up forms on high-intent pages, content upgrades, social and partner promotion, referrals, events; always with clear consent.

### Step 6. Protect deliverability
Authentication, list hygiene, easy unsubscribe, consistent sending.

### Step 7. Measure and improve
Clicks, replies, unsubscribes, list retention and business outcomes; review monthly.

## Issue structure (example)
```
Subject: one specific promise (avoid clickbait)
Preview text: extends the subject
Intro: two or three sentences, personal and direct
Main piece: one idea, with an example or data
Quick hits: two or three short links with commentary
From us: one product tip or event (optional)
Sign-off: name of a real person; invite replies
```

## Growth tactics
| Tactic | Notes |
|---|---|
| Sign-up on high-intent pages | Blog posts, guides, tools, footer |
| Content upgrades | Templates or checklists tied to the article |
| Social previews | Share one insight from each issue |
| Partner swaps | Recommend each other's newsletters |
| Referral programme | Rewards for sharing, with fraud checks |
| Events and webinars | Opt-in at registration |
| Archive pages | Public issues that rank and attract sign-ups |

## Metrics that matter
| Metric | Why |
|---|---|
| Click rate | Interest in content (opens are unreliable due to privacy features) |
| Replies | Strongest sign of connection |
| Unsubscribe rate per issue | Content or frequency problems |
| List growth by source | Which sign-up points work |
| 90-day subscriber retention | Whether readers stay |
| Business outcomes | Trials, demos, purchases or pipeline from newsletter readers |

## Subject line guidelines
- Make a specific promise the issue keeps.
- Use the reader's words for the problem.
- Keep it short enough to read on a phone.
- Avoid clickbait and false urgency; it erodes trust and future opens.
- Test angles over several issues rather than judging one send.

## Sign-up promise
Tell people exactly what they will receive and how often: "One practical idea every Tuesday. Five minutes to read. Unsubscribe anytime." Then keep the promise. A gap between the sign-up promise and the issues drives unsubscribes and spam complaints.

## Welcome email
Send a welcome immediately with the promise, the best past issues, a request to reply with what the reader wants to learn and instructions to add the address to contacts.

## Archive and repurposing
Publish past issues on a public archive page, and turn strong issues into blog posts, social threads and talks. Good issues earn search traffic and new subscribers long after sending.

## List hygiene
Remove hard bounces immediately, send a re-engagement email to subscribers who haven't clicked in six months and remove those who still don't engage. A smaller engaged list delivers better than a large inactive one, and mailbox providers reward engagement.

## Useful references
- Google email sender guidelines: https://support.google.com/a/answer/81126
- Ann Handley, Everybody Writes (2nd edition, 2022)

## Cadence choice
Weekly builds habit fastest; fortnightly suits small teams; monthly works for deep essays or data digests. Pick the rhythm you can keep for a year.

## Edge cases and judgement calls
| Situation | What to do |
|---|---|
| Small list | Focus on quality and replies; growth follows good issues |
| B2B with customers and prospects | Separate newsletters or segments by need |
| Falling opens due to privacy features | Judge on clicks, replies and retention |
| No time for weekly issues | Fortnightly or monthly, but consistent |
| Sponsors or ads | Disclose clearly; keep reader value first |

- Repurposing issues: `content-repurposing`
- Measurement: `content-pr-measurement`
- Deliverability and lifecycle email: the CRM and Lifecycle skills

## Worked example
A project management company sent a monthly newsletter of blog links and product updates; clicks were low and unsubscribes high. The relaunch promised "one practical idea for running client projects, every Tuesday", written by the head of customer success with real examples, plus two curated links and an optional product tip. Sign-up forms moved onto top guides with a template download. Within six months, click rates and replies rose sharply, the list grew steadily, and sales began citing the newsletter in deals.

## Output format
```
# Newsletter plan: <name>, <date>
## Promise and audience
## Type, format and cadence
## Content mix and issue template
## Growth plan
## Deliverability basics
## Metrics and review cadence
```



## Common mistakes
- No clear promise.
- Company news instead of reader value.
- Inconsistent sending.
- Buying or scraping lists.
- Judging success on opens alone.

## Questions to ask before you plan
- Why would someone look forward to this email?
- What can we deliver consistently with our team?
- How does the newsletter support business goals?

## Self-check before you answer
- Is the promise clear and specific?
- Is reader value the majority of each issue?
- Is growth permission-based?
- Are metrics beyond opens tracked?

When to use this skill, and when not to

Use it when launching a newsletter, when engagement falls, when list growth stalls, when the newsletter has no clear purpose and when building an owned audience alongside search and social.

A newsletter is one of the few channels a company owns outright. The best become something readers expect each week; most company newsletters are monthly link roundups that readers ignore.

Don’t use it for automated lifecycle sequences or deliverability in depth (use the CRM Email Deliverability skill and the CRM and Lifecycle skills).

Example prompts

  • “Relaunch our newsletter so people read it.”
  • “Write our newsletter promise and issue template.”
  • “How do we grow our newsletter list?”
  • “Which newsletter metrics should we track?”
  • “Weekly, fortnightly or monthly?”

Example output

The skill returns a fixed structure. A shortened example for an imaginary site:

# Newsletter plan: example PM software, 11 October 2026

Promise: one practical idea for running client projects, every Tuesday
Author: head of customer success
Mix: one main idea, two curated links, optional product tip
Growth: sign-up on top guides with a template download
Metrics: clicks, replies, 90-day retention, sales mentions

The plan starts with a one-sentence promise and judges success on clicks, replies and retention, because opens are unreliable.

What the agent needs from you

The skill asks for business goals for the newsletter, the audience and what they care about, list size, growth sources and engagement data, past issues and best performers, the email platform and sign-up points and team capacity.

How this skill hands off to related skills

Newsletters connect to the set: Strategy, Brand Voice, subject lines from Copywriting, reuse in Repurposing, metrics in Measurement and lifecycle email in the CRM and Lifecycle skills.

How to run Newsletter Strategy step by step

  1. Install the skill as newsletter-strategy/SKILL.md.
  2. Write the promise in one sentence.
  3. Choose type, format and cadence.
  4. Design the issue template.
  5. Plan growth and deliverability.
  6. Measure monthly beyond opens.

Situations this skill handles

Newsletters differ by audience. The skill handles these situations:

SituationWhat the skill does
Small listQuality and replies first
Customers and prospectsSeparate newsletters or segments
Falling opensJudged on clicks and replies
No time for weeklyFortnightly or monthly, consistent
SponsorsClear disclosure
Link roundup nobody readsRelaunch with a promise

What makes this skill different

Most company newsletters are link roundups. This skill builds a newsletter around a promise readers value, a consistent format and a real author, with growth based on permission and metrics that reflect actual reading.

It treats the newsletter as an owned audience that compounds, not a monthly obligation.

Practical tips from real projects

  • A clear promise.
  • Reader value first.
  • Consistency builds habit.
  • Measure engagement that matters.

A worked example: a project management company sent a monthly newsletter of blog links and product updates; clicks were low and unsubscribes high. The relaunch promised one practical idea for running client projects, every Tuesday, written by the head of customer success with real examples, plus two curated links and an optional product tip. Sign-up forms moved onto top guides with a template download. Within six months, click rates and replies rose sharply, the list grew steadily and sales began citing the newsletter in deals.

Newsletter types suit different audiences: a curated roundup with commentary for busy professionals in fast-moving fields, a single essay for founders and thought leaders, a tactical how-to for practitioners, a data digest for analysts and decision-makers, product and customer news for existing customers and a community newsletter for members.

An issue follows a simple shape: a subject line with a specific promise, preview text that extends it, a short personal intro, one main piece with an example or data, two or three quick links with commentary, an optional product tip or event and a sign-off from a real person inviting replies.

Growth comes from sign-up forms on high-intent pages such as guides and tools, content upgrades like templates and checklists, social previews of each issue, partner newsletter swaps, referral programmes with fraud checks, opt-ins at events and webinars and a public archive that ranks in search.

The sign-up promise tells people exactly what they will receive and how often, such as one practical idea every Tuesday that takes five minutes to read, and the issues keep that promise. A welcome email sent immediately repeats the promise, links the best past issues, asks the reader to reply with what they want to learn and explains how to add the address to contacts.

Subject lines make a specific promise the issue keeps, use the reader words for the problem, stay short enough for a phone and avoid clickbait and false urgency, with angles tested over several issues.

List hygiene removes hard bounces immediately, sends a re-engagement email to subscribers inactive for six months and removes those who still do not engage, because mailbox providers reward engagement.

Metrics focus on behaviour. Click rate shows interest in the content, since opens are unreliable. Replies are the strongest sign of connection. Unsubscribes per issue flag content or frequency problems. List growth by source shows which sign-up points work. Ninety-day subscriber retention shows whether readers stay. Business outcomes such as trials, demos, purchases or pipeline from newsletter readers show value to the company. Deliverability basics support all of this: authentication, list hygiene, an easy unsubscribe link and a consistent sending schedule. Strong issues are published on a public archive page and turned into blog posts, social threads and talks, so they keep earning subscribers long after sending. Sponsored sections are clearly labelled and never crowd out reader value.

Buying or scraping lists is never part of the plan; permission is what makes the audience valuable.

Frequently asked questions

A clear promise, consistent sending, mostly reader value and a recognisable voice.

The rhythm you can keep for a year: weekly builds habit fastest, fortnightly suits small teams, monthly suits deep essays.

Clicks, replies, unsubscribes per issue, list growth by source, 90-day retention and business outcomes.

Mailbox privacy features inflate and distort opens, so they no longer reflect real reading.

Sign-up forms on high-intent pages, content upgrades, social previews, partner swaps, referrals, events and a public archive, always with consent.

Keep most of each issue for reader value, often around 80%, with company content in proportion.
