How to write an email newsletter people read

Email is the only audience you own — no algorithm decides who sees it, and nobody can take the list away. Which makes it strange how badly most small business newsletters are done. They fail on two things, and neither is the writing: they are sent too often about the sender, and they arrive with a subject line that promises nothing.

Answer one question first

Why would somebody be pleased to see this in their inbox?

Not why you want to send it. Why they would want it. If the honest answer is "so they remember we exist", that is a reason to send something rarely and make it genuinely useful — not a reason to send a monthly round-up of your news.

Good answers: it saves them money, it warns them about something, it answers a question they have, it is genuinely interesting about a place they live. Every one of those is about them.

The subject line is most of the job

It is the only part that is guaranteed to be read, and it decides whether anything else is.

• Be specific. "Your boiler service is due — and why October is the cheapest month" beats "October Newsletter" by an enormous margin.
• Say the useful thing, do not tease it. Curiosity gaps work once and then teach people you waste their time.
• Keep it short enough to survive a phone. Most people see about forty characters.
• No urgency you have not earned. "LAST CHANCE" on a routine email is how you get marked as spam.

If you spend twenty minutes on a newsletter, spend five of them here.

What to actually send

The best small business newsletters are short, useful and slightly personal. A workable shape:

1. One useful thing. A seasonal warning, a common mistake, a genuine tip. This is the reason the email exists.
2. One human thing. A job you did, something that happened, a photograph. Short.
3. One clear offer or next step, at the bottom, and only if there genuinely is one.

Two hundred words is plenty. Nobody has ever complained that a newsletter was too short, and a long one gets saved for later and never opened.

What not to send: a round-up of your own news, a list of your services, a "we're still here" email, or anything that reads as an advert wearing a newsletter's clothes.

How often

Less than you think and more regularly than you will manage without deciding.

For most small businesses, monthly is plenty and quarterly is fine. The failure mode is not sending too little — it is sending weekly for six weeks and then nothing for a year, which is the same stop-start pattern that ruins social posting.

Pick a frequency you could hold through your busiest month, say it on the sign-up form so people know what they are agreeing to, and keep to it.

Write it as a person

The single biggest improvement most newsletters could make: write it the way you would email one customer you like.

That means plain first-person, no corporate voice, no "we are delighted to announce", and a real name in the from field rather than "info". People open emails from people. It also means the tone matches how you actually are, which is what your brand voice should be anyway.

Plain text, or something close to it, generally outperforms a heavily designed template for a small business — partly because it feels personal, partly because a wall of images with a slow-loading header does not.

The rules, briefly

Marketing email in the UK is regulated, and the parts that matter are simple.

• Consent. You generally need people to have agreed. There is a narrow exception for your own existing customers about similar products, but it comes with conditions — including an opt-out offered at the point you collected the address.
• Never buy a list. No consent, terrible results, and it damages your ability to reach the people who did sign up.
• A working unsubscribe in every email, honoured promptly. Make it easy — someone who cannot unsubscribe marks you as spam instead, which is far worse for you.
• Say who you are, with a real business identity in the email.

A plain summary, not legal advice. Whether you need a list at all covers the wider question.

What to measure, and what to ignore

Open rates have become unreliable — some mail apps pre-load images, which registers as an open nobody performed. Treat them as a rough trend rather than a number.

More useful:

• Clicks, which are a real action.
• Replies. The most underrated signal there is. A newsletter that gets replies is working.
• Unsubscribes. A small steady trickle is healthy. A spike means that email got something wrong — usually frequency or tone.
• Whether anything happened. Bookings, enquiries, someone mentioning it. That is the point.

A newsletter that takes twenty minutes

1. Keep a note during the month of questions customers asked. That is your useful thing, already chosen.
2. Pick the best photograph you took.
3. Write two hundred words: the useful thing, the human thing, the next step.
4. Spend five minutes on the subject line.
5. Send it to yourself, read it on your phone, fix what is awkward.
6. Send.

The bottom line

Answer why someone would be pleased to receive it before writing anything. Send monthly or quarterly, not weekly-then-never. Two hundred words: one useful thing, one human thing, one next step. Spend a quarter of your time on the subject line, write it as a person rather than a company, make unsubscribing easy, and judge it on clicks and replies rather than opens.
