Postcard — A6 · UK direct mail

What is an A6 direct mail postcard, and when should you use one?

An A6 postcard is the compact, low-cost end of addressed direct mail: a printed card, both sides, posted to a named person with no envelope to open. It is the cheapest way to put one offer and one call to action in somebody's hands, and it works best when the message is short and visual.

What actually arrives through the letterbox?

A printed card that lands face-up with no envelope, so the offer is read before anything is decided.

Compact two-sided marketing card. Exact geometry is locked to the supplied Stannp A6 Postcard Guide. Printed on 300gsm, addressed to a named person at a verified UK address, and posted through our print and post partner — never dropped door to door.

How does Lenny design it?

You describe the business and the offer. Lenny writes the copy, produces the artwork at the exact size the printer requires, and shows you both what it looks like and where every protected area sits.

01

Brief

Tell Lenny your business, your offer and who you want to reach. Bring your website or a menu if you have one.

02

Concept

Copy and layout produced at 154 × 111 mm, with the address area kept clear. Labelled a concept until a file is checked.

03

Verified print file

The file is measured against the printer's specification before it can be approved. Nothing is called print-ready until it passes.

04

Your approval

You approve, or ask for changes in plain words. Nothing is printed or posted without a person approving it.

Bringing your own artwork? Upload it and it is measured against the same specification. If it does not fit, you get a plain list of what to change — or we repair it and send it back for your approval.

What are the exact print measurements?

These come from our print partner's own published design guide, revision 2026-09-20. The same numbers drive Lenny's designs, our file checks and the order itself, so nothing can drift.

We build the audience

Tell Lenny the area and the kind of household or business you want, and we build a targeted list of UK addresses for the mailing.

Address data integration not connected yet — audience counts are shown as unavailable rather than estimated.

You bring your own list

Upload a spreadsheet of customers. Every row is checked for a usable street address and postcode, duplicates are collapsed, and anything unpostable is skipped with a plain reason rather than printed.

Honest limits

Postcard — A6 questions, answered

How much is an A6 postcard mailing?

One price per card covers printing and UK postage, falling with volume. The worked examples on this page come straight from our live price list.

Is it printed on both sides?

Yes, both sides are printed on card. Part of the reverse is reserved for the address and postal markings, and the exact protected area is shown on this page.

Is a postcard the same as a leaflet drop?

No. Every postcard is addressed to a named person at a real address. Unaddressed door-to-door leaflet distribution is a different service we do not offer.

How many should I send?

Small local tests of a few hundred are perfectly normal. Because unit prices fall with volume, larger runs cost less each — the price examples on this page show the difference.
