Writing a newsletter people open

A newsletter succeeds or fails on one question: does the next one get opened? Everything tactical is downstream of that.

Consistency of promise beats cleverness

The strongest predictor of a healthy newsletter is that readers know what they are getting and when. A clear, kept promise — this subject, roughly this length, this often — builds the habit that makes the open automatic.

Chasing a different angle each week, or going quiet for two months, breaks that. Most newsletters die of inconsistency rather than of bad writing.

One job per email

Decide the single thing this email is for. Inform, drive a click, sell, re-engage. Emails that try to do four things do none, and the click-through data will not tell you which failed.

If there is one action you want, there should be one obvious call to action.

Subject lines and preview text

The subject line's job is to make the promise legible, not to be clever. Curiosity gaps work once and train readers to distrust you. Specific beats mysterious.

Preview text is the second line the inbox shows and is routinely wasted on "view in browser" or nothing. It is roughly as much real estate as the subject line. Write it.

Neither is the main lever. Sender reputation and reader expectation decide most opens before the subject is read.

Voice

Newsletters that work read as written by a person to a person. The plural corporate voice is the default failure mode: it is safe, unreadable, and forgettable.

Structure for skimming

Most people skim. Short paragraphs, meaningful subheadings, one idea per section, and the most important thing first. If someone reads only the first two lines, they should still get the point.

What not to optimise

Send-time optimisation, emoji in subject lines, and open-rate A/B tests are the most discussed and least consequential variables — and since Apple Mail Privacy Protection, open-rate tests are measuring noise. Spend the effort on the promise and the consistency.

The unsubscribe is not the enemy

An easy unsubscribe is required for bulk senders, and it is also better for you than a spam complaint. Someone leaving cleanly costs you nothing; someone reporting you costs you reputation with every recipient at that provider.

What trips people up

• Optimising subject lines while the underlying promise is unclear.
• Writing for the whole list when the email is really for a segment.
• Burying the unsubscribe, converting departures into complaints.
