Examples of email newsletters: the shape of the issue decides whether it gets read, so here are six shapes and what each one is for

Most newsletter examples you will find are screenshots of a design, which is the least transferable part. What decides whether an issue gets read is its shape: how many ideas it carries, whether it is written by a person or by a company, and what it asks the reader to do at the end. Six shapes cover almost everything that works. Pick the one that matches what you actually have to say each month, because the commonest newsletter failure is a business choosing a shape it cannot fill and quietly stopping after four issues.

The six shapes, side by side

Shape	What one issue contains	Suits a business that	What makes it work
The single idea letter	One idea, explained properly, and nothing else	Sells expertise, and has a view worth hearing	The idea is specific enough to disagree with
The digest	Five to nine items, one line each, each with a link	Serves busy people in a fast moving field	The selection. Anybody can collect links; the value is what you left out
The product update	What shipped, what changed, what is next	Has something genuinely new most months	Each item says what it now lets the reader do
The operator's note	A first person account of what happened this month	Is led by a visible founder or owner	Including the parts that went badly
The offer issue	One offer, its terms, and a date	Sells a product with a price and stock or capacity	Sent because an offer exists, not because it is the first of the month
The teaching issue	One thing the reader can do this week, step by step	Sells something a buyer must understand first	The reader can finish the task without buying anything

Two of the six are hard to sustain and worth naming as such. The digest needs you to read widely every week, which is a real time cost most businesses underestimate. The product update needs an actual product cadence, and a business shipping nothing new runs out by issue three.

A worked issue of each

Square brackets are what you replace. These are constructed examples rather than copies of anybody's newsletter, which is deliberate: the shape transfers between businesses and the sentences do not.

1. The single idea letter, for a consultancy

• Subject: Why your [report] gets read and your [recommendation] does not
• Preheader: Three minutes, and one change to the first page
• Opening: One sentence stating the claim, not the topic.
• Body: The claim, the reason it holds, the one example you have seen, and the objection you expect, answered.
• Close: One question inviting a reply, because on this shape a reply is the result.

2. The digest, for a trade supplier

• Subject: [Six] things that changed in [category] this month
• Preheader: The price move, the rule change and one supplier to watch
• Body: Six items, one line each, each linking out, ordered by how much they affect the reader's cost.
• One line of your own judgement on the item that matters most. That line is the reason to read yours rather than the trade press.

3. The product update, for a software business

• Subject: [Feature] is live, and [the old limit] is gone
• Preheader: Plus the two smaller fixes people asked for
• Body: Three items. Each one names what it now lets the reader do, in their words rather than the feature name.
• Close: One instruction, usually to go and try the thing.

4. The operator's note, for a founder led brand

• Subject: What [month] actually looked like
• Preheader: The thing that worked and the thing that did not
• Body: First person. What you tried, the number it produced, what you are changing. One honest failure earns more trust than three successes.
• Close: An invitation to reply with the reader's own version.

5. The offer issue, for a shop or a service

• Subject: [The offer, with the number in it] until [day]
• Preheader: [The condition the subject had no room for]
• Body: One offer, its terms beside the price, one checkable piece of proof, one action.
• This shape has its own rules, including the sender and opt out lines a commercial email in the United States has to carry, and they are set out in the offer email template.

6. The teaching issue, for a business whose buyer has to learn first

• Subject: How to [do the small thing] in [time]
• Preheader: No account needed, and it works on [the thing they already use]
• Body: Numbered steps the reader can finish today, with the one mistake that wastes an hour called out.
• Close: The next step, which is where your product fits for the people who want it done rather than explained.

How to tell which shape your list wants

Use your own sends rather than a rule. Three readings answer it.

• Which past issues produced replies. Replies are the cleanest signal a small list gives, and they cluster hard around one shape. If your three most answered issues were all first person, your list wants the operator's note whatever your plan said.
• Which block earned the clicks. Compare clicks per issue by position: the main item against the short items against the action line. A list that only ever clicks the short items wants a digest.
• What people ask you. Read a month of support messages and sales calls. A list of recurring questions is a teaching newsletter already written.

Then hold one shape for at least three issues before judging it. Readers learn what to expect from you by repetition, so a newsletter that changes shape every month is measuring novelty rather than fit. One job per issue is the rule that survives all six shapes.

The part that does not change between shapes

Whichever shape you pick, the issue needs a fixed skeleton so it can be written quickly, and the footer is not optional: an accurate sender, a subject that matches what is inside, a valid physical postal address and a clear way to opt out. The block structure and those required lines are set out in full in the email newsletter template, which is the page to work from once the shape is chosen.

Where to find real newsletters to study

Studying real issues beats studying screenshots, and it costs nothing to set up properly.

• Subscribe from a separate address. Make one mailbox for this, subscribe to four competitors and four businesses you admire outside your category, and let it fill for a month. Cross category is where the ideas come from, because everybody in your category copies each other.
• Read the archives. Many newsletters publish every past issue on the web, so you can read a year in an hour without subscribing. Search the sender's name with the word archive.
• Keep a folder of the ones you finished. Not the ones you admired, the ones you read to the end. That folder is your shape, and it is usually a surprise.
• Note the subject line and the first line only. Those two decide whether anything else was read. Copy the pattern, never the words.

Newsletter examples: the questions behind the search

How long should a newsletter be?

Two minutes of reading, which in practice is one main item of 150 to 300 words plus two or three one line items. The digest shape runs shorter per item and similar in total. Anything longer belongs on a page with a link from the issue.

How often should I send?

Pick the interval you can hold in your worst month rather than your best. Monthly suits almost everybody, fortnightly suits a business with genuine new stock or news, and weekly needs either a team or a very narrow subject.

Can I mix two shapes in one issue?

One shape per issue, and the main item is where the shape lives. A single idea letter can carry two short items at the bottom without becoming a digest. What fails is an issue with two main items, because the reader cannot tell what it was for.

Should a newsletter sell?

Yes, once, at the end, and in the same voice as the rest. The offer issue is the exception where selling is the whole point, and keeping it as a separate send rather than bolting an offer onto every issue is what keeps the other five shapes readable.

Do I need a designed template?

A single column, left aligned, with real text and one image renders correctly everywhere and reads in a dark theme. Heavily designed multi column layouts break first on phones, which is where most of any list reads.

What do I do when I have nothing to say this month?

Send the shortest honest version rather than skipping, or move to a longer interval and tell the list you are doing it. A newsletter that arrives late and padded trains people to ignore it, and silence for two months costs more open rate than a three line issue ever would.

The issue you never get to write

A newsletter is the one channel where you choose every word a customer reads. There is now a channel where you choose none of them: a buyer asks ChatGPT, Gemini, Perplexity or Claude who to use in your category and gets back three or four companies with a sentence of description each, assembled from whatever has been published about you. For a business that has written careful issues to its own list for two years, the gap between the two descriptions is worth looking at once. AI Knows Us asks those buying questions across the main assistants and records who gets named and what the answers were built from.
