You'll find a lot of promotional merchandise content quoting precise-sounding recall and retention percentages for fridge magnets. We looked into where those numbers actually come from, and most trace back to marketing blogs citing each other rather than any traceable independent study. We're not going to repeat them here. The real case for fridge magnets as promotional merchandise doesn't need borrowed statistics, it holds up on the mechanics alone.
The mechanic that actually matters: forced repeat exposure in a no-competition location
A fridge magnet gets placed somewhere the recipient looks at multiple times a day, on an object that isn't shared advertising space the way a noticeboard or a shared inbox is. That's the entire structural advantage over most other promotional items: a pen gets used until it runs dry and then discarded, a tote bag gets used once and stored, but a magnet occupies a fixed spot with no other brand competing for that exact location. It doesn't need a high click-through rate to work, because it isn't trying to generate a click. It's trying to be present at the moment someone remembers they need a plumber, a takeaway, or a locksmith.
That's also its real limitation, worth being upfront about: a magnet on its own is unmeasurable. Nobody taps a fridge magnet. If a client asks for hard attribution, the magnet needs a measurable element built in before it goes to print, not bolted on afterwards.
Building a trackable element into the design
Three options, in order of how easy they are to set up:
A dedicated promo code per batch. "Quote MAGNET10 for 10% off" is trivial to track through your existing order or booking system, and it separates results by batch if you run multiple designs or locations.
A short, campaign-specific URL rather than the homepage. Something like clientsite.co.uk/spring rather than the generic homepage, so any traffic landing there is attributable to the magnet rather than mixed in with general site traffic. This is far more reliable than a generic QR code pointing at a homepage, which gives you a scan count but no way to separate magnet-driven visits from anything else.
A QR code carrying UTM parameters if the client uses Google Analytics or similar. A QR code encoding a URL like clientsite.co.uk/?utm_source=magnet&utm_campaign=spring2026 gives a clean, filterable data source in the client's existing analytics setup, at no extra cost beyond generating the code correctly before it goes to print.
Pick one of these before you finalise the design, not after. Retrofitting a tracking element onto an already-approved design usually means resubmitting for client sign-off, which costs you the turnaround time you were trying to protect.
Sizing the order without guessing
A rough working rule: order to cover 100% of your expected reach for the campaign, plus 15 to 20% buffer for reprints, staff samples, and stock giveaways that don't map cleanly to "one recipient, one magnet." Two common sizing scenarios:
Event-driven (trade show, conference): size against expected footfall, not stand visitors alone, since magnets often get taken by people who walk past without stopping. If the event expects 2,000 attendees and your stand typically reaches a third of them, 700-800 units plus buffer lands you around 850-1,000, which is also where the per-unit price curve starts flattening out (see the multiplier table in our bulk pricing guide, where the jump from 500 to 1,000 only improves the rate by 8 more points).
Retention-driven (existing customer base): size against your actual mailing or service list, not an aspirational number. A magnet mailed to 3,000 existing customers is a retention play with a known denominator, which makes it easier to justify to a client than a speculative "brand awareness" run with no defined audience.
Fitting production into a campaign timeline
- 12 days out: brief finalised, including the trackable element (promo code, campaign URL, or UTM QR) and the exact quantity
- 11 days out: order placed, digital proof requested
- 10 days out: client approves proof (this step is often where agencies lose the most time, since it depends on the client's own turnaround, not the supplier's)
- 10-9 days out: production begins, 1-week turnaround from approval
- 2-3 days out: delivery, with buffer for any courier delay
- Event day: stock on hand, tracking element live
The step most agencies underestimate isn't production, it's client approval. Building slack into the client sign-off window, rather than the production window, is usually the difference between a comfortable timeline and a last-minute scramble.
What to gather before you brief a magnet run
- Fixed delivery deadline, if there is one, and what it's tied to
- Expected reach (footfall, mailing list size, existing customer count), not an aspirational figure
- Whether the client needs exact colour matching to existing brand collateral, or whether this design is standalone
- Which trackable element you're building in, and who owns checking the analytics afterwards
- Whether this is a one-off run or the first of a recurring campaign, since that changes how much colour/design documentation is worth locking in now for reordering later
Getting it made
Once the brief is set, build the quote against your real quantity and size directly. The price you see is the price validated at checkout, not a placeholder that gets recalculated later. Every order is UK manufactured, delivered free anywhere in the UK, and produced on a 1-week turnaround from proof approval.
