What Is a Newsletter? Definition, Types, Examples & How to Create One
.webp)
A newsletter is a regularly distributed email (or print) publication that delivers curated content, updates, and news to a subscribed audience. Subscribers opt in to receive it, and the best newsletters lead with value rather than a hard sell. This guide covers what a newsletter is, the main types, what one should contain, how to create and design one, and how it differs from broader email marketing and from a blog.
What is a newsletter?
A newsletter is a recurring message sent to a list of subscribers who have chosen to receive it, delivering content, updates, and news on a consistent schedule. The defining feature isn't the format, it's the intent: a newsletter exists to build an ongoing relationship with an audience by giving them something genuinely useful each time, rather than to push a single one-off promotion or to send a transactional receipt. The audience subscribes, the sender shows up reliably, and engagement is measurable on every send.
That distinction matters and sets up the comparisons later in this guide. A promotional email drives a specific action once; a transactional email confirms something the recipient did (an order, a password reset). A newsletter is different from both: it's an ongoing, scheduled relationship with people who asked to hear from you.
Why send a newsletter? Purpose and benefits
Newsletters build trust, authority, and a direct relationship with an audience over time, which is why they remain one of the most durable channels in marketing. The main benefits:
- Relationship and trust – showing up regularly with useful content keeps a brand front of mind and builds familiarity that one-off ads can't.
- Authority – consistently sharing insight, curation, or expertise positions the sender as a credible voice in their field.
- You own the audience – unlike social media followers (rented from a platform that can change its algorithm overnight), an email list is owned media. You control the relationship and can reach subscribers directly regardless of any platform's rules.
- Measurability – every send produces data: open rate, click-through rate, and conversions tracked per campaign, so you can see what works and improve it.
- Nurture and convert – newsletters move subscribers from awareness through to conversion over time, turning casual readers into leads and leads into customers.
Types of newsletters
Newsletters are most usefully categorised by purpose rather than format:
- Company or product newsletters – updates, announcements, and news from a business to its customers or prospects.
- Editorial or content newsletters – curated insight, analysis, or roundups on a topic, the dominant format for media brands and publishers.
- Creator or personal newsletters – individual writers and creators publishing directly to subscribers, often on platforms like Substack or Beehiiv.
- Internal or employee newsletters – communication within an organisation, keeping teams informed and aligned.
Those purpose-based categories are then delivered through one of a few formats. The email newsletter is by far the most common today; print newsletters still exist (membership organisations, schools, local communities), and web-based or browser newsletters are a smaller third format. The purpose usually matters more than the format when deciding what to send.
What does a newsletter contain? The 6 key elements
A well-structured newsletter is built from six core elements, each doing a specific job.
- Subject line – decides whether the email gets opened. Aim for clarity or curiosity in under ~50 characters.
- Header / branding – logo, brand colours, and the newsletter name, so subscribers recognise the sender instantly. Strong, consistent branding here is the difference between an email that looks trustworthy and one that looks like spam.
- Body content – the core value: articles, tips, curated links, or updates. Keep it focused, one to three topics per send, with a clear visual hierarchy so the most important thing is read first.
- Visuals – images and graphics that break up text and reinforce the message. Balance matters: too many can trigger spam filters, and every image should earn its place rather than decorate. Mobile-first matters, most newsletters are read on a phone.
- Call to action (CTA) – the one thing you want the reader to do next. A single, clear CTA outperforms competing links.
- Footer – unsubscribe link (legally required), sender address, and social links.
What to include in a newsletter and how to create one
Creating a newsletter is a short, repeatable process. The five steps below take it from goal to send.
Define your audience and goal
Start with the goal, what is this newsletter for? Building authority, nurturing leads, driving traffic, retaining customers? Then define the audience specifically: who they are, what they care about, and what would make them genuinely glad to open your email. The goal and audience together determine everything else.
Choose your content
Decide what value each issue delivers, original insight, curated links, product news, tips, or a mix. Keep each issue focused on one to three topics; a newsletter trying to cover everything ends up communicating nothing. Lead with your strongest content.
Choose an email platform
You'll need an email service provider (ESP) to manage the list, build the email, send at scale, and report on performance. Common options include Mailchimp, HubSpot, Klaviyo, and Brevo. The platform matters less than consistency and content, any of the major ESPs will do the job for most senders.
Design your newsletter
Design is where a newsletter earns or loses attention in the first second. The essentials: a clear visual hierarchy (the eye should land on the most important thing first), brand consistency (the same logo, colours, and type as the rest of your brand, so it's instantly recognisable), mobile responsiveness (most opens happen on a phone, so the layout has to work on a narrow screen), and optimised images (compressed for fast loading, with the message readable even if images don't render). Good newsletter design isn't decoration, it's what makes the content easy to read and act on. Need your newsletters designed and on-brand every time?

Send, measure, and iterate
Send on a consistent schedule, then track how each issue performs and use what you learn to improve the next one. The metrics that matter are covered below.
Newsletter examples that work
A few well-known newsletters show how the same six elements play out across very different categories:
- Editorial (e.g. The Hustle, Morning Brew) – these work because of a strong, consistent visual identity, a conversational voice, and tight curation: a few stories per issue, scannable formatting, and a clear hierarchy that respects the reader's time.
- Creator (e.g. a Substack writer's weekly letter) – these work on personality and consistency. The design is usually minimal, the value is the writing and the relationship, and the regular cadence is what keeps subscribers engaged.
- Product / B2B (e.g. a SaaS company's monthly update) – these work when they lead with genuine value (a useful tip, an industry insight) before the product news, use clean on-brand design, and keep a single clear CTA rather than cramming in every announcement.
The common thread is structure and restraint: one clear purpose per issue, strong recognisable branding, and a design that makes the content effortless to read on any device.
Effective newsletter strategies
Frequency and timing
Weekly is the most common cadence, but daily suits news formats and monthly suits research-heavy content. Consistency matters more than frequency: pick a schedule you can sustain, tell subscribers what to expect, and show up reliably. An erratic newsletter loses subscribers faster than an infrequent but dependable one.
Personalisation and segmentation
Segmenting the list (by interest, behaviour, or stage in the customer journey) and personalising content to each segment consistently lifts engagement. A relevant email to a small, well-defined segment outperforms a generic email to the whole list.
Measuring success – key metrics
Every send produces data. These are the metrics to watch and rough benchmarks to judge them against, though your own historical trend matters more than any industry average. Note that since Apple's Mail Privacy Protection launched in September 2021, reported open rates are inflated because Apple pre-loads email content, which is why click-based metrics are now the more reliable signal.
Sources: Brevo and WebFX 2026 email benchmarks. Because Apple MPP inflates open rates, treat click-through and click-to-open rates as the truer measure of engagement, and benchmark against your own trend before any industry average. Verify current figures against a named source such as Brevo, WebFX, or Litmus before relying on them.
Newsletter vs email marketing vs blog
"Newsletter", "email marketing", and "blog" are often used loosely. Here is how they actually differ.
All newsletters are email marketing, but not all email marketing is a newsletter, and newsletters and blogs work best together, not in competition. Many brands repurpose blog content into their newsletter and use the newsletter to drive traffic back to the blog.
How newsletters have evolved
Newsletters predate the internet, organisations, clubs, and businesses circulated printed bulletins to members and customers for well over a century. The format moved online with the rise of email in the 1990s and 2000s, which made distribution instant, global, and effectively free, and made performance measurable for the first time.
Today the newsletter is in the middle of a genuine revival, driven by creator platforms like Substack and Beehiiv and by brands rediscovering the value of owned media as social reach becomes less reliable. Modern newsletters are mobile-first (most are read on a phone), increasingly interactive, and often personalised with the help of automation and AI. The throughline across all of it is unchanged: a regular, valued message to an audience that chose to receive it.
Frequently asked questions
How often should I send a newsletter?
There is no universal rule, weekly is the most common cadence, but daily suits news formats and monthly suits research-heavy content. Consistency matters more than frequency: pick a schedule you can sustain, tell subscribers what to expect, and show up reliably every time.
What is a good newsletter open rate?
A standard open rate sits around 20–21% (Brevo's 2026 data puts marketing email at 20.73%), though dashboards often show higher figures (around 34% MPP-inclusive) inflated by Apple Mail Privacy Protection. Open rate varies widely by industry and list quality, and your own historical average is a better benchmark than any global figure. Click-based metrics are now more reliable than opens.
What is the difference between a newsletter and a blog?
A blog lives on your website and is found through search (pull); a newsletter lands directly in a subscriber's inbox (push). They are complementary, many brands repurpose blog content into newsletters and use newsletters to drive traffic back to the blog.
How do I grow my newsletter subscriber list?
Add clear signup forms to your website, give people a compelling reason to subscribe (exclusive content, early access, or a useful resource), and promote across your other channels. Never buy email lists, they harm deliverability and breach most platform terms.
How long should a newsletter be?
Most effective newsletters take three to five minutes to read, often 500–1,000 words for editorial formats, and shorter for curated link roundups. Don't pad to hit a word count; respect the reader's time and lead with your strongest content.
Turning a newsletter into a habit your subscribers look forward to
A newsletter is, at its core, a regular and valued message to an audience that chose to hear from you, and the ones that work combine genuinely useful content with design that makes it effortless to read. If you're starting one, begin with a clear goal and a sustainable schedule; if you're improving one, the fastest win is usually better, more consistent design.
