Direct mail gets dismissed as the channel everyone moved on from. Worth remembering why they moved: it costs more per contact than anything else, it is slower, and for a while digital looked like it did the same job for a fraction of the price.
Then everybody’s inbox filled up, and the economics quietly changed.
Scarcity is the whole argument
The average person receives a great deal of marketing email and very little marketing mail. A letter now arrives into an almost empty channel.
That is not a claim about paper being inherently persuasive. It is a claim about competition for attention. Your email is one of a hundred that morning. Your letter might be the only thing in the box that is not a bill.
It also survives longer. An unopened email is gone by Thursday. A well-made mail pack sits on a kitchen bench for a week, and other people in the household see it.
Where it genuinely works
High-value purchases. If the thing you are selling is worth thousands, a few dollars per contact is a rounding error. The channel’s cost only looks high when the product is cheap.
Audiences that are hard to reach digitally. Not everyone is reachable by email, and not everyone who is reachable pays attention. A postal address is one of the most stable pieces of information about a household.
The end of a sequence. Mail is an excellent closer. Run email and SMS first, see who engaged, then send something physical to the people who showed interest. You are spending real money only on people who have already raised a hand.
Anything local. If your business serves a catchment, mail selected at SA1 level — areas of a few hundred people — puts you in the right streets rather than the right postcode.
Where it does not
Low-value products with thin margins. Anything that needs to happen this week. Audiences you cannot describe geographically. Tests where you need an answer quickly, because the feedback loop is weeks rather than hours.
It is also unforgiving. An email with a mistake can be followed by a correction. A mail pack with the wrong offer is sitting in sixty thousand houses and there is nothing to be done about it.
Selection matters more here than anywhere
When a contact costs a fraction of a cent, waste is an annoyance. When it costs dollars, waste is the whole campaign.
This is where a fine selection pays for itself most obviously. A postcode-level mail drop sends the same pack to every household in a box that might span dozens of suburbs. An SA1-level selection sends it to the pockets where your buyers actually concentrate — a smaller run, a better list, often the same total cost and a much better result.
The arithmetic is simple. If half your mail is going to households that were never going to buy, you are not running a mail campaign. You are running a smaller mail campaign and burning the rest.
Running it without a separate supplier
The usual reason mail does not get tested is logistics. The data is in one place, the email platform in another, the mail house somewhere else, and coordinating a sequence across all three is more work than the test is worth.
We handle mail alongside email and SMS. Same selection, same schedule, same reporting. Which means a mail component is a decision rather than a project, and a small test is actually viable.
Worth a test, not a religion
Nobody should move their budget to mail on the strength of an article. But if you have a high-value product, a defined geography, or a sequence that currently ends with an unanswered email, it is worth finding out what a physical follow-up does.
Start with a few thousand to the warmest part of your list and compare it honestly against doing nothing. That is a cheap question to answer.
