Who magnetic cards work for
A magnetic card is a bet that your customer will need you again, possibly in a hurry, and will not remember your name when they do. The more that description fits your business, the better magnets perform.
| Business | Why a magnet helps | What to feature |
|---|---|---|
| Plumber, HVAC, electrician | Emergencies happen at home | Emergency number in large type |
| Locksmith or towing | Urgent, rarely planned | Phone number and service area |
| Pizza or takeout | Repeat orders from home | Phone, website and a signature item |
| Veterinarian or pediatrician | Families call often | Phone, hours, after hours line |
| Pest control or lawn care | Seasonal reminders | Phone and a seasonal service line |
| Real estate agent | Long term name recognition | Name, photo and phone |
Businesses that are rarely contacted from home, such as B2B consultants or law firms, usually get less value from magnets than from a well made paper card.
How magnetic cards are made
Flexible magnets are typically made from a ferrite powder mixed into a plastic binder and formed into thin sheets. For magnetic business cards, a printed card face is combined with a thin magnetic backing, then cut to size. The result is thicker and heavier than a paper card and bends rather than creasing.
Most flexible magnets are magnetized so the holding force is concentrated on one side, which is why the back sticks firmly while the printed front does not. They hold light paper items well, but they are not meant to hold heavy items. Check the product page for the exact size and thickness before you design.
Design for the fridge, not the wallet
A paper card is read at arm's length. A magnet is read from across a room, often by someone in a hurry. That changes the priorities.
Make the phone number the largest text on the card, well beyond the size you would use on a paper card. A number set at 18 to 24 pt can be read from several steps away, while an 8 pt number on a fridge is invisible. The business card font size guide covers paper card sizes; for magnets, scale up. Put the service in plain words above or beside the number, such as 24 Hour Plumbing or Pizza Delivery.
Cut everything else to the minimum. Skip the address unless people visit you. Skip social handles. Use strong contrast, such as dark text on white or white text on a deep color. Your logo can be smaller than usual; recognition comes from the service and number.
Content that earns a spot on the fridge
People keep magnets that are useful. A plain logo magnet may get tossed, while a magnet with information people refer to can stay for years.
- An emergency or after hours line, clearly labeled
- A simple schedule, such as trash pickup days or school terms, printed alongside your details
- A reminder, such as Change your furnace filter every three months
- A reorder prompt, such as Order your usual with one call
- A short menu of best sellers for food businesses
- A QR code to book service or reorder online
If you include a QR code, keep it large and give it a clear border so it scans from a fridge door at an angle. The QR business card guide explains sizing.
Getting magnets onto fridges
The best distribution method is the one where your magnet arrives at the moment the customer is thinking about you. For service businesses, that means after a completed job. Hand the magnet over as you finish and say, put this on the fridge in case anything else comes up. Many customers will do exactly that.
Other routes work too. Include magnets with invoices, delivery orders or welcome packs. Pair them with door hangers in neighborhoods where you are already working. Send them in envelopes or attached to direct mail postcards for a seasonal campaign. For trades with vehicles, matching car magnets on your van reinforce the same name and number around town.
Tradeoffs to weigh
Magnetic cards cost more per piece than paper cards, and current prices appear on the product page. They are heavier and thicker, which matters for mailing: a magnet in an envelope can change postage costs and may need a stiffer envelope. They do not fit well in wallets or card holders, so they are not a good replacement for your everyday networking card.
There is also a question of volume. Magnets work best given to people likely to need you, not handed out to everyone at a crowded event, where many will be discarded. Plan them as a customer retention tool alongside your paper cards rather than instead of them.
Measuring whether magnets work
Because magnets act over months, results can be hard to see. Build in a way to measure them. Use a dedicated phone number or extension printed only on the magnet, a short link or QR code that opens a page only magnet holders see, or an offer code such as FRIDGE10. Ask new callers how they found you and note the answer.
After six months, compare the calls or orders tied to the magnet against the number you gave out. Even a small response rate can pay off if each job is valuable. A plumber who gets a handful of calls from a few hundred magnets may cover the cost with one job.

A magnet stays on the fridge for years, so the Business Card Launch Kit helps you make sure every line on it stays true. The wording worksheet is especially useful for magnets, where you need to cut the message down to one service and one number.

Frequently asked questions
Do magnetic business cards work?
They work well for services people need again at home, such as plumbing, food delivery and pet care, because the number stays visible on the fridge. They are less useful for general networking.
How strong are magnetic business cards?
They are designed to hold themselves and light paper items on metal surfaces such as fridges and filing cabinets. They are not meant for heavy objects.
Can I mail magnetic business cards?
Yes, but they are heavier and thicker than paper cards, which can affect postage. Weigh a sample in its envelope before a large mailing.
What should I put on a magnetic business card?
Lead with the service and a large phone number. Add something useful, such as an after hours line, a schedule or a reorder QR code.
