Every business wants the same thing from direct mail — to be remembered. But most mailers fail at that one job. They arrive, get glanced at, and disappear. The message never lands. The phone never rings.
Magnetic mailers are built differently. Instead of giving people something to read and discard, they give people something to use and keep. That shift — from disposable to displayable — is exactly why businesses using magnetic mailers are consistently outperforming those relying on traditional postcards.
This post covers everything you need to know about magnetic mailers, how MagnetbyMail's StuckUp Mailers work, and why this format is one of the most cost-effective marketing decisions a local business can make right now.
Magnetic mailers are direct mail pieces with a magnet physically attached to the postcard. The recipient receives a full-color printed card with a magnet affixed directly to the back. They peel off the magnet, stick it somewhere useful, and your brand is now part of their daily environment.
Unlike folded formats that enclose a magnet inside, the StuckUp Mailer style from MagnetbyMail attaches the magnet directly onto the postcard surface using permanent glue. It's a clean, simple format that delivers your message and leaves behind a branded magnet in a single step.
The result is a postcard with magnet attached that recipients engage with immediately — and don't throw away.
The direct mail industry has studied consumer behavior for decades, and the conclusion is consistent: people respond to utility. Give someone something useful and they keep it. Give them something purely promotional and they discard it.
That's the entire strategic advantage of magnetic mailers.
Magnets earn a permanent spot in the home. Refrigerators, filing cabinets, office whiteboards, and garage doors are prime real estate. A magnet that holds a grocery list or a to-do note earns that spot by being helpful. Your brand rides along for free every single day.
Repetition without repeat spending. You pay for the mailing once. But a well-placed magnet generates brand impressions every time the recipient opens their fridge — which happens an average of 15 to 20 times per day. Over a month, that's hundreds of free impressions from a single piece.
Magnetic postcards printing stands out in the mailbox. A postcard with a magnet attached has a slightly different feel and weight than standard flat mail. That tactile difference creates curiosity and improves open rates before the piece is even read.
Format flexibility for every type of message. Because the entire postcard surface is your canvas, magnetic mailers force clarity. Your best offer, your key message, and your call to action stay front and center.
MagnetbyMail has designed the StuckUp Mailer to be one of the most accessible magnetic mailer formats on the market. The concept is straightforward: a full-color postcard printed on 10-point matte card stock with UV coating on the front, inkjet-addressed on the back from your mailing list, and a 1″ × 3″ magnet attached with permanent-strength glue.
Two styles are available to fit different campaign needs and budgets.
Postcard size: 3.625″ × 8″ with a 1″ × 3″ magnet attached.
