Most direct mail campaigns fall flat before a single piece is printed. The brief is vague, the list is too broad, and the copy leads with the business rather than the reader. This guide walks through each stage of planning a campaign that actually generates responses, from setting a goal you can measure to tracking which version of your offer pulled best. Whether you're targeting Watford postcodes or the wider Hertfordshire area, the fundamentals are the same.

Start With the Outcome, Not the Format
The first question isn’t “shall we do a leaflet or a letter?” It’s “what do we want someone to do after they read this, and how will we know they did it?” Without a single, measurable goal, you end up with a piece that tries to do everything and achieves nothing.
“Brand awareness” is the most common vague brief, and it’s the hardest to justify when someone asks what the campaign delivered. A specific goal looks more like this, generate 20 enquiries in 30 days, or redeem 50 vouchers before the end of the month. That number shapes every decision that follows, including which format you choose, what offer you make, and how you track response.
Set the target before you brief anyone on design or print. If you can’t name the number, the campaign isn’t ready.
Building Your Target List
List quality matters far more than list size. Sending 5,000 pieces to a broad, poorly matched audience will almost always produce weaker results than sending 1,500 to people who genuinely fit your offer.
For businesses targeting Watford and the surrounding towns, geographic selection is the obvious starting point. You can target by postcode district, by a radius from a specific address, or by named areas such as Rickmansworth, Chorleywood or Borehamwood. From there, demographic selects narrow the audience further, household income bands, age ranges, property type, or for B2B campaigns, company size and sector.
Reputable list brokers supply data cleaned regularly against the Mailing Preference Service. Cheap, unverified data is a false economy. High bounce rates waste print and postage budgets, and mailing someone who has opted out creates a poor first impression before they’ve even read your offer.
Writing Copy That Gets a Response
The single biggest mistake in direct mail copy is leading with the business. “We’ve been serving Watford since…” is not an opening that makes anyone want to read on. Start with the reader’s problem, the thing that keeps them up at night, or the outcome they want but haven’t found yet.
The three things every direct response piece needs
First, one clear offer, specific enough that the reader knows exactly what they’ll get. Second, a real deadline, because without one, responding tomorrow becomes never. Third, a single obvious next step, whether that’s calling a number, scanning a code, or visiting a page. These don’t work in isolation. If any one of them is missing, the piece underperforms.
Keep the copy shorter than you think it needs to be. On a postcard, every word earns its place. On a letter, lead with the strongest point rather than warming up for two paragraphs. Read it aloud before approving it. If any sentence sounds like it was written by a committee, rewrite it.
Choosing the Right Print Format
Postcards and leaflets
Format affects both cost and how the piece lands with the reader. Postcards are the most immediate option. There’s no envelope to open, so the offer is visible the moment the piece is picked up. They work well for short, punchy offers with a strong visual, though the limited space means they suit a single message rather than anything that needs explaining.
Folded leaflets give you more room. A four-page A5 fold lets you walk through a problem, present your solution, and close with the offer, all in a format that costs less to post than an A4 sheet. If your offer has moving parts, or your audience needs a little more context before they’ll act, a folded format earns its extra cost. Our leaflet printing covers a range of sizes and fold options if you want to compare what suits your campaign.
When a letter is the right call
Letters carry more perceived weight than a glossy leaflet, particularly for B2B campaigns or higher-value offers. A signed letter on headed paper reads differently from a promotional flyer. That difference matters when the decision you’re asking someone to make isn’t a small one.
Tracking What Worked
If every respondent comes through the same phone number or the same contact form, you’ll never know whether the campaign drove the enquiry or something else did. Build a tracking layer in before you post anything.
Dedicated phone numbers are the simplest option. A call tracking number rings through to your main line but logs every call separately, so you can count responses precisely. QR codes pointing to a dedicated landing page do the same thing online, and they let you see not just who scanned but what they did next. Promo codes are useful when the response happens in person, at a till or in a booking system, where a URL or phone number is less natural.
Use at least one of these on every campaign. The data from a modest first run tells you which offer pulled, which format worked, and what the cost per response came out at. The next campaign starts from a stronger base rather than the same guesses.
Running the Campaign From Watford
Working with a local print and direct mail provider cuts the back-and-forth that slows most campaigns down. Artwork errors get caught before the job goes to press rather than after 3,000 pieces have been posted. Turnaround is faster because there’s no freight delay, and if something needs adjusting at proof stage, a phone call usually sorts it the same day.
For businesses in Watford and the surrounding area, that proximity counts for more than it sounds when a campaign has a fixed end date and the response window is tight.
