Most newsletter advice is about writing. This page is about structure — the repeatable shape that makes a newsletter easy to write every week and easy to read every week. The two are related: newsletters die because the writer runs out of energy, and a template is the thing that stops that happening.
Five complete templates below, covering the formats that actually sustain. Copy the one that matches how you think.
The structural rule that matters most
A newsletter needs a fixed skeleton and variable content. Readers learn the skeleton within three issues and start skimming to the part they like. Writers stop facing a blank page, because the question changes from “what shall I write?” to “what goes in section two?”
The failure mode is redesigning the format every issue. It exhausts the writer and gives the reader nothing to anchor on.
Template 1 — The one-idea newsletter
The most sustainable format for a solo writer, and the easiest to keep good. One idea, properly argued, nothing else.
Subject: {{The idea, stated as a claim}}
Preheader: {{The counter-intuitive part, in eight words}}
{{ISSUE NUMBER}} • {{DATE}}
Hi {{first_name}},
{{One-sentence hook. The surprising observation.}}
{{Two or three paragraphs developing it. A concrete example.
What most people assume, and why it is wrong.}}
{{What to do about it — two or three sentences, specific.}}
That’s it for this week.
— {{sender_first_name}}
P.S. {{One line: a link, a question, or something you are reading.}}

Why this works
- The subject line states a claim, not a topic. “Why discounting kills your best customers” beats “This week: pricing thoughts”. A claim creates a question in the reader’s head; a topic label does not.
- The issue number builds a collection. Readers who see #47 assume 46 previous ones were worth writing. It is a small credibility signal that costs nothing.
- It ends where it ends. “That’s it for this week” is a real feature — readers reward newsletters that respect their time by opening the next one.
- The P.S. is the most-read line after the subject. Put the one link you actually want clicked there, not buried mid-body.
Template 2 — The curated roundup
Best when your value is filtering rather than originating. Sustainable because the raw material already exists.
Subject: {{Number}} things worth your time this week
Preheader: {{The most interesting one, named}}
Hi {{first_name}},
{{One or two sentences on the through-line connecting this week’s picks.}}
1. {{TITLE}}
{{Source}} • {{read time}}
{{Why it matters — your take, not the summary.}}

2. {{TITLE}}
{{Source}} • {{read time}}
{{Your take.}}

One more thing: {{a short personal note, or something you shipped.}}
See you next {{day}}.
— {{sender_first_name}}
Why this works
- Your commentary is the product, not the links. Anyone can aggregate. The reason someone subscribes is your judgement about why a thing matters. If you delete your take and the newsletter still works, it is not a newsletter, it is an RSS feed.
- Read times reduce the cost of clicking. “4 min” converts better than an unlabelled link because it removes the unknown.
- Three to five items. Ten is a chore. Three is a curation.
- “One more thing” is where the personal lives — it keeps a curated format from feeling automated.
Template 3 — The company or product update
For B2B and SaaS. The trap here is writing for yourself instead of the reader — internal milestones nobody outside the company cares about.
Subject: What’s new in {{product}}: {{the single best thing}}
Preheader: Plus {{second thing}} and {{third thing}}.
Hi {{first_name}},
The short version: {{one sentence on the most useful change.}}
{{HEADLINE FEATURE}}
{{What it does, in the reader’s language. What it replaces or removes.
One sentence on who it helps most.}}

From the blog
{{Article title}} — {{one line}}
What we’re working on next: {{one honest sentence.}}
— {{sender_first_name}}, {{company}}
Why this works
- Every item is framed as a problem solved. “Added bulk export” is a changelog. “Export 50,000 contacts without a support ticket” is a benefit. Same feature.
- One headline feature, then a list. Giving five features equal weight means none registers.
- “What we’re working on next” earns disproportionate goodwill. It costs nothing and makes readers feel like insiders — and it sets expectations you can be held to, which is a good discipline.
- Naming the fixes builds trust. Admitting something was broken and is now fixed reads as honest, and customers who hit that bug feel heard.
Template 4 — The ecommerce newsletter
Selling without only selling. A newsletter that is purely product blocks becomes a promotion your subscribers learn to ignore.
Subject: {{Seasonal or editorial hook}} — and what’s new in
Preheader: {{New arrival}}, plus {{the useful bit}}.
Hi {{first_name}},
{{Two or three sentences of genuine editorial. A seasonal note,
a behind-the-scenes detail, a customer story, how something is made.}}
NEW THIS WEEK
[Image] {{Product}} — {{price}}
{{One line on why it exists or who it is for.}}

[Image] {{Product}} — {{price}}
{{One line.}}
[ View → ]
STILL POPULAR
{{Product}} • {{Product}} • {{Product}}
{{Closing editorial line — something human.}}
— {{sender_first_name}}, {{company}}
Why this works
- Editorial first, products second. The opening paragraph is what makes this a newsletter rather than a catalogue, and it is what gets it opened next month.
- Two new products, not twelve. Depth beats breadth — a reason to want each one converts better than a grid.
- “Still popular” is social proof disguised as convenience.
- Frequency discipline matters more here than anywhere. Ecommerce lists are where over-mailing does the most damage — see email frequency best practices.
Template 5 — The plain-text personal letter
No design, no images, no columns. Consistently among the highest-engagement formats, and the least fashionable.
Subject: {{Written like you would write to one person}}
Hi {{first_name}},
{{Open with something that happened. A conversation, a mistake,
a thing you noticed. Specific and small.}}
{{Draw the general point out of it. This is the substance —
two or three paragraphs.}}
{{Land it. What you would do differently, or what you want the
reader to consider.}}
If you have thoughts, just hit reply. I read everything.

{{company}} • {{postal_address}}
[Unsubscribe]
Why this works
- It looks like a real email, so it is read like one. Heavy HTML templates signal “marketing” before a word is read.
- Plain text is more deliverable. Fewer images, fewer tracked links and a better text-to-HTML ratio all help inbox placement.
- The reply invitation is genuine and it works. Replies are a strong positive engagement signal for mailbox providers — relevant to sender reputation.
- It scales down beautifully. A list of 200 gets the same experience as a list of 200,000.
The parts every newsletter needs
- A sender name a human would recognise. A person plus the company usually beats the company alone for small brands. Never “noreply”.
- A subject line that makes a claim. More patterns in email subject line formulas.
- Preview text written deliberately. Left empty, clients pull the first line of the body — often “View in browser”. See email preview text.
- A physical postal address. Required by CAN-SPAM in the US and equivalents elsewhere. See CAN-SPAM explained.
- A working one-click unsubscribe. Required by Gmail and Yahoo above 5,000 daily messages, and honoured within two days.
- A consistent send day. Predictability is what turns a list into a habit.
Frequently asked questions
How long should a newsletter be?
Long enough to make one point well. The one-idea format runs 300–600 words; a curated roundup 400–800. Length matters far less than consistency — a good short newsletter every week beats an excellent long one every other month.
Plain text or designed HTML?
Plain text or lightly styled wins for personal, B2B and creator newsletters. Designed HTML wins for ecommerce, where the product image is the argument. When unsure, start plain — it is faster to write, more deliverable, and easier to sustain.
How often should I send?
Weekly is the sweet spot for most. Monthly is enough to be forgotten between issues; daily is a serious commitment that most abandon. Whatever you choose, state it in the welcome email and keep to it.
What day is best?
Consistency beats the calendar. Pick a day, keep it, and let your audience learn it. If you want the data rather than the principle, see the best day and time to send email.
Send your newsletter without a per-subscriber bill
Newsletter platforms almost all charge per subscriber, which means a growing list raises your bill whether or not those subscribers read anything. Bluey Email charges on emails sent, so a list that grows faster than your send volume does not inflate the invoice.
