How to write a great newsletter

The most common reason newsletters die is that the writer chose a format that was too demanding to sustain. Before writing your first issue, decide on a format you can execute every single week — not just when you have time or inspiration.

Newsletter format types: - Curated links: You gather 5–10 of the best links on a topic each week with short commentary on each. Low writing effort, high curation effort. Works well for busy niches (tech, finance, design). Example: "Here are the 7 most interesting things I read about AI product design this week." - Original essays: One long-form original piece per issue. High effort, highest perceived value. Builds the deepest relationship with readers. Best if you have genuine expertise and 3–5 hours per week to write. - Tutorials and how-tos: Step-by-step educational content. "How I cut my AWS bill by 40% this month." Extremely shareable and high-value. Works for any skill-based niche. - News digest: Summary and analysis of recent news in your niche. Requires staying current and fast turnaround. Strong for fast-moving industries. Readers come for your take, not just the news. - Q&A: Answer one reader question per issue in depth. Low research overhead once you have a reader base. Scales naturally — the more subscribers, the better the questions. - Personal updates: A mix of what you're thinking, working on, reading, and learning. The "letter from a smart friend" format. Works best when the writer is the product — their perspective, life, and work are the draw. - Bundle / roundup: Combines a short original intro, 3–5 curated links, a recommendation, and a closing thought. The most popular format for general-interest newsletters because it sets clear expectations.

The format should match what you can sustain — not what sounds most impressive. A short curated newsletter sent every week for two years beats an ambitious essay series that runs for three months and then goes quiet.

Voice is the reason readers stay subscribed to a newsletter that covers the same ground as ten others. Information is everywhere. A perspective they trust — delivered in a voice they enjoy — is rare.

The difference between corporate and personal voice is the difference between "It has been observed that remote work presents challenges for team cohesion" and "Remote teams are harder to hold together than people admit. Here is what I have actually seen work." One is hedged, passive, and forgettable. The other is direct, embodied, and has a point of view.

Write as yourself, not as a brand. The biggest mistake new newsletter writers make is writing as if they represent an institution. Unless you genuinely are a brand (a publication, a company newsletter), write in first person, include your own experience and failures, and let your opinions be visible. "I tried X for three months and here is what I found" is always more compelling than "research suggests X may be effective."

Consistency matters more than perfection. Your voice will be different in issue 3 than in issue 30. That is fine. What matters is showing up with genuine effort each time, not achieving a perfect voice before you start. Readers who find you early get to watch the voice develop — that creates loyalty.

How to find your voice: Write faster and edit less. Most voice problems come from over-editing — you sand down the interesting, idiosyncratic phrases and replace them with safe, generic ones. Write your newsletter draft quickly, edit only for clarity and factual accuracy, and leave the character in. Read your draft out loud before sending. If it sounds like something you would say to a smart friend, you are close. If it sounds like a corporate memo, cut it back down.

Your subject line is the only thing that determines whether an issue gets read. You can write the best content of your life, and it will sit unread if the subject line does not earn the open. Treat subject lines as a discipline, not an afterthought.

The 5 subject line types: - Curiosity gap: Creates a question the reader needs to resolve. "The mistake I made that cost me 400 subscribers." The curiosity gap works but gets old fast — do not use it every issue or readers stop trusting you. - Benefit-led: States the value clearly upfront. "3 ways to cut your newsletter production time in half." Clear, honest, scannable. Works reliably across industries. - Question: Poses a question the reader is already thinking. "Is weekly really better than monthly?" Questions work because they imply the answer is inside. - News / recency: Ties the issue to something current. "What the Substack vs. Beehiiv shift means for independent writers." Works for news-adjacent niches; requires timely content. - Personal / direct: Writes as if to a specific person. "A framework I keep coming back to." Feels intimate. Works especially well for personal-voice newsletters.

Character limits: Subject lines should be 40–50 characters for most email clients. Mobile clips at around 40 characters in portrait orientation. Write your primary message in the first 40 characters; everything after is bonus.

Preview text: The grey line below the subject line in most inboxes is your second headline. Most writers leave it blank, letting the email client default to "View in browser" or the first sentence of the email. Always write custom preview text — 50–90 characters that extend or contrast the subject line.

What to avoid: - ALL CAPS in subject lines — flags spam filters and reads as shouting - Excessive punctuation — "You will NOT believe this!!!" trains readers to ignore you - Misleading clickbait — opens once, then destroys trust permanently - Generic fillers like "Issue #47" or "Weekly digest" — tells the reader nothing about why this issue is worth their time

A/B testing: If your platform supports it, test subject lines on a subset of your list before sending to everyone. Even a 20% sample gives meaningful data. Test one variable at a time — length, format, or tone — not multiple changes at once.

Most newsletters are read in fragmented attention — on a phone between meetings, at breakfast, during a commute. Structure your issues for this reality, not for a reader sitting in a quiet library with unlimited time.

Hook in the first 3 lines. The opening of your newsletter determines whether the reader keeps going or switches apps. The first sentence should answer "why does this issue matter today?" — not "good morning, here is my weekly update." Get to the point, or get to a story that pulls the reader in. Never open with an apology for being late, a weather comment, or logistics about your life that the reader did not ask about.

Section length: Most newsletter sections should be 100–200 words. Main essays can run longer — 400–800 words — but need to earn each additional paragraph. If you are writing a link roundup, each link should have 2–4 sentences of commentary: enough to tell the reader why it matters, not so much that it competes with the linked piece.

Headers and dividers: Use a simple visual break (a horizontal rule, a section header, or white space) between distinct sections. This allows readers to scan, skip to what interests them, and return to finish later. A wall of text with no visual breaks is the fastest way to lose a mobile reader.

One main CTA per issue. Every issue should have one primary action you want readers to take: read the linked piece, reply with their answer, sign up for a workshop, share with a colleague. Multiple calls to action compete with each other and readers end up taking none of them.

"One Big Thing" vs. bundle format: - One Big Thing: One long original piece. Readers know exactly what they are getting. Easiest to focus. Hardest to sustain — requires strong ideas every week. - Bundle: A mix of original content, links, and recurring sections. Readers know the structure and can navigate directly to their favourite part. Easier to produce because you can lean on curation when you are short on original ideas.

Choose one and stick to it for at least 3 months. Consistency of format builds reader habits.

The single biggest predictor of newsletter success is consistency. A newsletter that arrives every Tuesday at 8am for two years builds a habit in its readers. A newsletter that arrives "whenever I have something to say" does not.

Start biweekly before committing to weekly. Biweekly (every two weeks) feels slow at first but gives you room to find your voice, build a production process, and see what resonates before committing to the pressure of weekly. Most writers who burn out do so because they committed to weekly in week one and had no process in place for when life got busy.

Batch-write issues ahead. The writers who sustain newsletters over years all share one habit: they write ahead. On a good week, write two issues instead of one. On an inspired day, write half a future issue. Build a 2–4 issue buffer and protect it. When your buffer runs out, reduce your frequency before you miss a send.

The minimum viable newsletter: If you are stuck, publish one insight, 200 words, on schedule. "The most interesting thing I learned this week and why it matters to you." A short issue sent on time is far more valuable than a comprehensive issue sent three weeks late. Readers forgive brevity. They do not forgive silence.

What to do when you run out of ideas: - Return to your readers: Reply prompts, polls, and Q&A sections generate content from your audience. "What is the most important challenge you are facing right now?" fills two future issues. - Revisit your archives: "Here is something I wrote two years ago — and here is what I think about it now." Evergreen content with fresh perspective is genuinely valuable. - Constraints generate ideas: "I will write about one tool I use every day" or "I will share the most counterintuitive thing I read this week" removes the blank-page problem. - Ship the draft you have: The newsletter you actually send is worth more than the perfect one you are still writing. Readers forgive imperfect issues. They do not forgive going dark.
