The honest answer: anywhere from 25p to £2.50 per piece. Which is not helpful.
The useful answer is in how that number is built. If you are budgeting a direct mail campaign and every supplier you ask comes back with a different figure, it is not because they are being dishonest (most are not). It is because four different things get bundled into ‘the price’ and depending on which of those four matters most to your campaign, the number moves.
After thirteen years of running a mailing house, here is the breakdown I wish every client saw before they asked for their first quote.
The four costs of a direct mail campaign
Every direct mail campaign has exactly four cost components. Every quote you ever receive is some combination of these four. If a quote does not break them out, ask for one that does.
1. Data (list + cleaning)
If you have your own list, this is usually the cheapest part. You will still want it cleaned before printing, de-duplicated, address-validated, and mortality-screened. Expect £30–£80 for cleaning a list of 10,000 records. Worth every penny. A list that has not been cleaned in 18 months has roughly 15-20% bad addresses on it. You pay postage on every one of those, and they never land.
If you are buying a list, costs vary wildly. A rented consumer list runs around £80–£150 per thousand for one-time use. Business lists are higher; specialist lists (e.g. high net worth, specific industries) are higher still. If someone is offering you a ‘full consumer database’ for £50, the data is probably stale or the supplier does not have the right licence. Walk away.
2. Print
Where most of the ‘it depends’ lives. Key drivers:
- Format. A simple A5 postcard prints cheaper than a folded leaflet, which prints cheaper than a personalised letter in an envelope.
- Stock. Silk 250gsm is standard for postcards; premium stocks roughly double the paper cost.
- Colour. Full colour both sides is standard now; single-colour is no longer significantly cheaper on digital presses.
- Quantity. Direct mail gets dramatically cheaper per piece at volume. 500 is expensive per piece. 50,000 is not.
Typical 2026 print costs:
| Format | 1,000 pieces | 10,000 pieces | 50,000 pieces |
|---|---|---|---|
| A5 postcard, full colour both sides | £0.1o each | £0.06 each | £0.05 each |
| A4 folded to DL | £0.28 each | £0.14 each | £0.09 each |
| Personalised letter + envelope | £0.35 each | £0.18 each | £0.12 each |
Those are typical figures from a mid-size UK mailing house. Bigger houses go lower at volume; boutique houses with specialist finishing go higher. None of these are set in stone they move with paper prices and press availability.
3. Fulfilment (addressing, enclosing, sorting)
The often-forgotten cost. Fulfilment is everything between the press and the postman.
- Inkjet addressing on a postcard: £0.01–£0.02 per piece
- Machine-enclosing a letter with insert: £0.03–£0.05 per piece
- Hand-fulfilment (non-standard sizes, unusual inserts): £0.15+ per piece. Avoid if you can.
If your campaign involves personalisation — variable data printing, different offer codes per recipient, and different images per segment add roughly 20-30% to fulfilment costs. But this is often the single biggest response-rate driver in a modern direct mail campaign and worth the uplift on any campaign where you have enough data to personalise meaningfully.
4. Postage
The bit that most clients do not scrutinise enough. Postage is now the single largest line item in most campaigns.
Current 2026 indicative rates for business mail (subject to confirmation against the live Royal Mail rate card at quote time):
- Advertising Mail, small letter (under 100g), machine-sortable: around £0.30–£0.34 per piece
- Mailmark discount for machine-readable, properly-presented mail: an additional few pence off per piece
- Large Letter and Letter above the weight threshold: noticeably higher — worth checking if a format change keeps you in the cheaper band
Here is where to pay attention. Postage should be a pass-through cost. When we quote at Mailings Direct, the Royal Mail figure appears on the quote exactly as Royal Mail charges it. We charge separately for handling.
If your quote bundles ‘postage and handling’ into one line and the supplier will not break it out, they are usually marking postage up. We have seen charities charged £1,600 of hidden markup on a £4,200 mailing. Ask the question: ‘What is the postage element and what is the handling?’ If they will not tell you, you already know.
A worked example: 10,000 A5 postcard campaign
Here is what a fairly typical 10,000-piece B2C postcard campaign costs on 2026 rates. Numbers are realistic mid-range figures, not ‘cheapest available’ and not ‘premium’:
| Component | Cost |
|---|---|
| Data cleaning (your list) | £60 |
| Print — A5 postcard, full colour both sides, 10,000 | £900 |
| Fulfilment — inkjet addressing | £150 |
| Postage — Advertising Mail, small letter, Mailmark | £3,000 |
| Handling / fulfilment management | £200 |
| Total | £4,310 |
| Per piece | £0.43 |
Notice that postage is 70% of the campaign cost. This is why it matters whether your supplier is honest about postage. A 20% markup on that figure would add £600 you never knew you paid. Over a year of mailings, that is a four-figure sum.
What to actually ask for when you brief a supplier
If you want an apples-to-apples quote from three mailing houses — which is the right thing to do — give them all the same brief, and ask for these specifics back:
- Print cost only, before postage and fulfilment
- Postage, stated separately, at the Royal Mail rate
- Fulfilment / handling, stated separately
- Data handling charges, if any
- The cut-off time for same-day or next-day dispatch (and whether there is a deadline surcharge)
- What format, weight and sortation they are quoting against — because a £0.02 postage saving per piece compounds fast on 50,000 records
Then compare apples to apples. One supplier cheaper on print but vague on postage is not cheaper. One supplier 10% more expensive on print but transparent on every line is usually the one to pick.
The hidden cost nobody talks about
Reprints and resends.
If your data were not cleaned properly, you pay to print and post pieces that will never arrive. If your file was supplied in the wrong colour space and the print goes to press anyway, you pay for a run that looks wrong. If the deadline slips and you miss the event the mailing was promoting, the whole thing was free — to the person who did not send it.
The cheap quote that costs you a reprint is not cheap. Ask any supplier us included what percentage of jobs they reprint each year. If the number is vague, it is higher than they want to admit.
In summary
A direct mail campaign in 2026 costs whatever the data, print, fulfilment and postage components come to. That is it. A supplier who cannot show you those four numbers separately is either inexperienced or hoping you will not ask.
If you want a quote you can actually compare, ask for it in four parts.
And wherever you get it, do this one thing before you sign it off: check that postage is at cost, not marked up. That is the single line that has cost our clients the most over the years before they came to us.
