Email marketing

Newsletter

A newsletter is a recurring email sent to a whole list on a chosen rhythm. It is one format of email marketing, and it suits fewer businesses than it is sold to.

A newsletter is a recurring email sent to your whole list on a rhythm you chose. It is one format of email marketing rather than the whole of it, and the distinction matters because the newsletter is the format most businesses start with and the format fewest of them sustain.

In short

  • A newsletter is scheduled and goes to everybody. A flow is triggered and goes to one person.
  • The list is the asset. Any single issue is disposable.
  • The cadence you announce is a promise, so choose one you can keep in a busy month.
  • Most newsletters stop because nobody decided in advance what would fill them.

What separates a newsletter from the rest of your email

Two things: who receives it, and what caused it to send.

A newsletter is sent to a whole list, or to a large segment of one, at a time somebody on your side picked. Nothing the reader did triggered it. Compare that with an email flow, where a purchase, a signup or an abandoned basket starts a message aimed at one person while the thing that prompted it is still fresh in their mind.

The consequence is that a newsletter has to be interesting to a room rather than relevant to a person. That is a harder brief, and it is why a business with limited time should build the flows first. The flows are written once and keep delivering. The newsletter has to be written again every month, forever.

One more difference sits underneath both. The newsletter is disposable and the list is not. Any single issue is read once and forgotten inside a day, while the set of addresses behind it holds its value for years and grows slowly if you let it. Businesses that judge the whole effort on how well one issue performed are measuring the wrong object entirely.

Which businesses one suits

A newsletter earns its place when the business has genuine recurring news and a reason for customers to hear it before other people do.

  • Shops with a changing range. New arrivals, restocks and seasonal lines give a monthly send something concrete to carry.
  • Businesses whose customers buy repeatedly. Food, supplies, services on a cycle. The reader has a live reason to pay attention.
  • Trades and services with seasonal timing. Rainy season preparation, annual servicing, inspection deadlines.
  • Anybody publishing regularly. If guides or articles are already being written, the newsletter is a distribution channel and not new work.

It suits a business poorly when purchases are once in a decade, when the customer list is tiny enough that individual emails are better, or when nobody has been given the time to write it. In those cases the honest answer is transactional messages and flows, sent well, and no newsletter at all.

List size changes the calculation less than people expect. Two hundred addresses belonging to real customers is a useful list, and it can carry a quarterly note that produces actual work. Twenty thousand addresses gathered from a competition are not a list, they are a deliverability problem waiting for its first send. The number to watch is how many of them asked to be there.

What goes in one when you are not a publisher

Businesses freeze here because they picture a magazine. A newsletter for a trade or a shop is closer to a note from somebody who knows the subject.

  • What changed. New stock, new services, new hours, a branch opening.
  • The question you kept answering. Whatever customers asked repeatedly this month, answered properly once.
  • What the season is about to do. The problem arriving in six weeks, and what to do about it now.
  • One thing people get wrong. A short correction of a common mistake in your field.
  • A single clear next step. One action, not five competing links.

Decide those recurring sections before the first issue rather than after the third. Almost every abandoned newsletter was abandoned because each edition started from an empty page, and a fixed shape removes that.

Cadence, and the promise inside it

Choosing a rhythm is making a commitment to somebody who did not ask how busy you are.

Monthly works for most businesses. Quarterly is respectable and much easier to hold. Weekly is a publishing operation, and small teams who announce it usually stop by the second month, at which point the list has learnt that the promise was not real. The safest test is the busy season: pick the interval you could still manage during your worst week of the year, and send more often only when something genuinely warrants it.

Sending less often than you promised is a smaller problem than sending filler to hit a date. Readers forgive a gap. They stop opening after two issues that wasted their time, and once somebody stops opening, the mailbox provider starts noticing too.

Announce the rhythm once, on the signup form, and then meet it. Somebody who agreed to a monthly note and received nine emails in a fortnight did not agree to that, and an unsubscribe is the polite version of what happens next.

Why most newsletters stop after four issues

The pattern repeats closely enough to predict.

  • Nobody owns it. It belongs to everybody, so it is written by whoever is least busy on the day, which is nobody in month three.
  • The material was never planned. The first three issues used the obvious news and the fourth had none.
  • It is about the business. Awards, anniversaries and office photographs interest the office. The reader wants something usable.
  • The results were judged too early. Two sends produced nothing dramatic, so it was quietly dropped before the list had learnt to expect it.

Fix the first two and the rest tend to follow. Name a person, agree the sections, and write the subject line last, once you know what the issue actually contains.

Words you will hear

  • List. The set of addresses that have agreed to receive your email.
  • Segment. A defined part of the list, such as past customers or one city.
  • Broadcast. A one-off send to a list, as opposed to a triggered message.
  • Cadence. How often the newsletter goes out.
  • Churn. The steady rate at which addresses unsubscribe or go inactive.

A newsletter is worth starting when there is a person to write it, material to fill it and a rhythm the business can hold. Where those three are missing, the same hour spent on the messages customers already receive after buying will return more, and the list will still be there when the newsletter makes sense.

Questions we get

More about newsletter

How is a newsletter different from an email flow?

A newsletter goes to the whole list at a moment you choose. A flow goes to one person at a moment their behaviour chose, such as buying, abandoning a cart or signing up. The newsletter is written fresh every time and read once. A flow is written once and delivered for years, which is why the flow usually earns more for the same effort.

How often should we send one?

As often as you have something a customer would want. Monthly suits most businesses and quarterly suits several more. Weekly is a commitment very few small teams keep past the second month, and a rhythm you announce and then abandon reads worse than never having started. Pick the interval you can hold in your busiest season.

What do we write about when nothing has happened?

That question is the signal to send less often rather than to invent filler. Businesses that struggle here are usually publishing a bulletin about themselves. Turning it around solves it: what a customer asked you this month, what is in stock now that was not, what changes with the season, what people get wrong about the thing you sell.

Should we buy a list to start one?

No, and it damages more than it helps. Addresses collected without consent produce complaints and bounces, both of which mailbox providers read as evidence you should be filtered, and that reputation then applies to the messages your real customers wanted. Under Philippine rules consent also has to be freely given and specific, which a purchased list cannot demonstrate.

Is a newsletter still worth doing when everyone is on social media?

It answers a different problem. Social reach is granted by a platform and can be reduced without notice. A list is a set of addresses you hold and can contact directly. The newsletter is slower and smaller and it belongs to you, which is the entire argument for it.

What should we measure?

Clicks and replies ahead of opens. Open rate has become unreliable because privacy features load images automatically and register an open nobody performed. Clicks show interest in something specific, replies show a person on the other end, and unsubscribes tell you honestly whether the rhythm and the content match what people expected.

Can one newsletter serve customers and prospects at once?

It can, and it usually reads as written for neither. Somebody who bought last week and somebody who signed up yesterday need different things. If the list is large enough to split, split it. If it is not, write for the customer, because that is the person with a reason to keep reading.
