# Newsletter writer
A newsletter is a standing invitation that can be withdrawn at any time. Every issue either renews
it or spends it.
## Decide the job before writing
One issue, one job: teach something, argue something, or sell something. Issues attempting all three
achieve the first two badly and the third not at all.
## Subject line and preview
They are read together and should not repeat each other — the preview extends the subject rather
than echoing it. Never leave the preview to default to the first line of the body, which is usually
"View in browser."
What works: specific over clever, a claim over a topic, curiosity that the issue actually resolves.
What does not: questions the reader can answer "no" to, manufactured urgency, and anything that
overpromises relative to the body. Overpromising buys one open and costs the next five.
## Opening
The first sentence decides whether the rest is read. Start inside the story or with the claim — no
throat-clearing, no "hope you're well," no explaining what the newsletter is about.
Cut your first paragraph after drafting. It is almost always warm-up you needed to write and the
reader does not need to read.
## Structure
Short paragraphs. One idea each. Enough white space that the issue looks readable before it is read
— people decide whether to read from the shape of the thing.
Signpost where the issue turns, so someone skimming still gets the argument. Most readers skim.
## Voice
The thing that makes a newsletter worth opening is that it sounds like a person. Specifically:
- **First-hand detail.** What you actually did, saw, or got wrong. This is the part nobody else can
write, and the part most drafts leave out.
- **Opinions with a stance.** Balanced surveys of both sides are forgettable.
- **Varied rhythm.** Uniform sentence length reads as generated, because it is what generated text
does.
- **Concrete nouns and real numbers** in place of abstractions.
Avoid the register tells: "In today's fast-paced world," "it's no secret that," "let's dive in,"
tricolon everywhere, and every paragraph the same length.
## Selling without spending trust
Earn the ask. When an issue sells, the value comes first and the pitch is clearly marked — readers
forgive a clear pitch and resent a disguised one.
One call to action per issue. Multiple asks split attention and reduce all of them.
## Getting replies
Replies are the strongest signal a newsletter is working, and they improve deliverability more than
any technical fix.
Ask one specific question, occasionally rather than every issue, and make it easy to answer in a
sentence. "What did I get wrong here?" outperforms "let me know your thoughts," which asks the
reader to do the work of deciding what to say.
Then reply to the replies. A newsletter where the author answers is a different product from one
where they do not, and readers tell each other about the first kind.
## Editing
Three passes, in order: **structure** (is the order right, is anything missing), **cut** (remove
what does not advance the argument), **read aloud** (anything you stumble over gets rewritten). The
read-aloud pass catches what silent reading never does.
## Repurposing
One issue contains several short-form posts, a talk track, and often a longer piece. Plan which
before writing, so the sections that should stand alone are written to.
## Never
- Write a subject line the opening does not pay off. It buys one open and costs the next.
- Sell in an issue that gave nothing else. The trust spent is not recovered by the next good one.
- Send an offer to the whole list when it applies to part of it.
