Direct Mail in a Digital Decade

A leaflet on the doormat has one useful advantage over another social post: it occupies physical space. A homeowner can leave it beside the kettle, pin it to a noticeboard or hand it to a partner. That does not make it effective by default. Most poorly targeted print still goes straight into the recycling.

For a local business, direct mail works best as a precise invitation: a relevant service, delivered to a sensible catchment, with a clear reason to respond. The task is not to make print compete with every digital channel. It is to find where a physical reminder helps someone take the next step, then measure whether that step pays.

Start with the audience, not the postcard

Before asking a printer for prices, write down who should receive the piece and why. “Everyone within five miles” is a delivery area, not a customer definition. A dog groomer might focus on existing clients who have not booked for six months. A garden maintenance firm might select streets with suitable gardens inside its current working patch.

There are two practical routes: addressed mail to named recipients, and unaddressed delivery to selected areas. The first allows tighter customer selection and personalisation. The second can suit businesses with broad household relevance, such as takeaways, window cleaners or local venues.

Use the customer list you already understand

Existing customer records offer a useful starting point because you know what people bought and roughly when they might need it again. Remove duplicates, check addresses and exclude recent buyers if the offer would annoy them. Before using personal data, check the applicable privacy and direct marketing rules, your lawful basis and any objections or suppression records. A previous purchase is not permission for every use.

Choose streets for operational reasons

For area delivery, consider travel time, property suitability and capacity. Winning three cleaning customers on one street may be more valuable than winning three across town. Check how the delivery provider defines its routes: postcode boundaries and delivery rounds may not match the neighbourhood you have in mind.

Work backwards from the break-even point

A cheap print quote is not a campaign budget. Include design, printing, postage or distribution, list costs, tracking setup and handling responses. Then calculate the contribution from a completed sale: revenue minus the variable costs of delivering that sale, including any promotional discount.

The figures below are illustrative planning assumptions, not supplier quotes or response benchmarks. Replace them with your own costs before committing.

Campaign item	Assumption	Total
Printing	1,000 pieces at £0.20	£200
Delivery	1,000 pieces at £0.65	£650
Design and setup	Fixed cost	£150
Total campaign cost	Before fulfilment costs	£1,000
Contribution per first order	After discount and variable costs	£80
First-order break-even	£1,000 divided by £80, rounded up	13 orders

Thirteen orders from 1,000 delivered pieces means a 1.3% purchase response rate. If one in four enquiries becomes an order, you need 52 enquiries, or 5.2% of recipients. This distinction matters: a supplier quoting a response rate may mean enquiries rather than paying customers.

A mailing has not paid for itself because people noticed it. It has paid for itself when attributable contribution covers the campaign cost.

Repeat purchases may improve the economics, but use observed retention rather than hoped-for lifetime value. If first orders lose money, decide in advance how much you can afford to invest and how long you can wait for payback.

Give the recipient one useful reason to act

A strong mail piece answers three questions quickly: is this for me, why should I care, and what do I do next? Lead with the customer’s situation rather than the company biography. “Boiler service appointments available in Westbrook this October” gives a householder more to work with than “Quality, reliability and excellence since 2008”.

Make the offer specific without sacrificing margin

A discount is only one option. A repair business could offer a fixed-price inspection. A studio could promote a paid beginner session with equipment included. A retailer could invite nearby customers to reserve stock for a preview evening. State the price, inclusions, eligibility and genuine deadline clearly.

• One main promise: name the result or service the recipient can expect.
• One credible proof point: use a genuine customer comment, relevant qualification or specific service commitment.
• One primary action: book, call, order or visit, rather than four equally prominent requests.
• Essential reassurance: include your business name, service area, contact details and material offer conditions.

A postcard suits a simple invitation. A letter provides room to explain a more considered purchase. Choose the smallest format that communicates comfortably, not the smallest type that fits. Print a full-size proof and read it at arm’s length before approval.

Connect the printed piece to a measurable response

A QR code is useful, but it is not a measurement plan. Send it to a dedicated page that repeats the offer and makes the promised action easy on a phone. Include a short, readable web address as an alternative. For audiences that prefer calling, make the phone number prominent.

Use a campaign code in your booking or checkout system, and record the source of telephone enquiries. Brief staff before delivery begins: they should recognise the offer, know its conditions and log outcomes consistently. Test the code, form and booking flow on an actual phone using the printed proof.

1. Record the delivery: quantity, area, campaign version and expected delivery window.
2. Capture enquiries: calls, forms, bookings and visits associated with the campaign.
3. Track completed business: paid orders, cancellations, revenue and contribution.
4. Set a review date: allow for the buying cycle rather than declaring a result after three days.

Keep scans and page visits separate from sales. One person may scan twice, while another may type your business name into search and buy without using the code. Ask new customers how they heard about you, but recognise that attribution will remain imperfect.

Run a test you can learn from

Start with a quantity you can afford to lose, provided it is large enough to produce useful evidence. In the example above, 1,000 pieces need 13 orders to cover costs. Two orders would be a clear warning; 14 would be encouraging, but not proof that a much larger campaign will perform identically.

Change one major variable at a time. Test the same offer in two suitable areas, or compare two offers across comparable groups with equal quantities. Splitting a small run into six creative versions usually leaves too few responses to distinguish a useful signal from chance.

If practical, retain a comparable group that receives no mailing and compare purchase rates over the same period. This helps check whether you are claiming credit for orders that would have happened anyway. For existing customers, randomly assigning eligible records to mailed and unmailed groups makes that comparison more credible.

Review delivery quality as well as creative performance. Request the provider’s available delivery evidence and investigate obvious gaps. If results justify another run, expand gradually and check capacity: a successful offer becomes expensive if slow replies or missed appointments waste the demand.

Conclusion: make print earn another run

Direct mail deserves a test when you can identify a relevant audience, make a worthwhile offer and track the resulting business. Start with the economics, keep the message focused and judge completed sales rather than attention. The next mailing should be funded by evidence, not enthusiasm for the first design.
