Postcard Magnet Printing: What It Is and Why It Works

You've probably seen them on a neighbor's fridge. A colorful little card with a magnet attached, promoting a pizza place, a plumber, or a local real estate agent. You may not have thought much about it at the time — but that's exactly the point.

That magnet has been sitting there for weeks. Maybe months. Every time someone opens that refrigerator, they see the business name, the phone number, the offer. The owner of that magnet paid for one mailing. The impressions have been free ever since.

That's the quiet power of postcard magnet printing — and it's why smart local businesses are choosing this format over traditional direct mail year after year.

This guide covers how postcard magnet printing works, the different formats available, and how MagnetbyMail makes it simple for any business to launch a campaign that sticks.

What Is Postcard Magnet Printing?

Postcard magnet printing is the process of producing a direct mail piece that combines a full-color printed postcard with a custom magnet attached using easy-peel glue. The two pieces travel together through the postal system and arrive as one unit. The recipient reads the postcard, peels off the magnet, and puts it somewhere useful.

It sounds simple because it is. But the results are anything but ordinary.

According to the Direct Marketing Association, postcard magnets are read at least 52% more than postcards alone. Recipients notice immediately that the piece feels different — and that curiosity drives them to look more carefully. Even more striking: adding a magnet to a postcard can increase response rates by over 73% compared to a flat mailer.

The reason is straightforward. A magnet has utility. People keep useful things. And 72% of recipients recall receiving a promotional magnet even two years later. No digital ad, no flat postcard, and no email campaign comes close to that kind of retention.

The Four Postcard Magnet Formats From MagnetbyMail

MagnetbyMail has been producing postcard magnets since 2011, working closely with USPS to ensure every piece meets postal guidelines and arrives in perfect condition. They offer four distinct product lines, each suited to a different type of campaign.

1. Postcard Magnets — The Classic Format

The original and most popular format. A full-color postcard with a custom magnet attached using easy-peel glue and mailed via the post office. Four styles are available in MagnetbyMail's signature series, making this the most flexible option for businesses of all sizes. Whether you need a small reminder card or a larger promotional piece, this format covers it.

2. Foldup Magnet Mailers — Maximum Print Space

The Foldup Mailer takes postcard magnet printing to the next level. A large postcard is folded in half with the magnet enclosed inside. When the recipient opens the mailer, they're greeted with four panels of full-color printing — giving you room for photography, service listings, testimonials, pricing, and a strong call to action, all in one piece.

This format is ideal for businesses with a more complex message: financial advisors, healthcare providers, home service companies, or any brand that needs more than a single panel to tell their story.

3. StuckUp Mailers — All-in-One Simplicity

StuckUp Mailers are the most direct expression of postcard magnet printing. The magnet is permanently affixed to the back of the postcard with full-strength glue, turning the entire piece into a magnetic billboard. The whole postcard becomes your message — front, back, and the magnet itself.

Two sizes are available: the Little StuckUp (3.625″ × 8″) for menus, coupon strips, and phone listings, and the Major StuckUp (5.25″ × 8.5″) for campaigns that need more visual real estate. Every order includes free setup, a free digital proof, and complete mailing services — address validation, inkjet addressing, USPS form processing, and post-office drop-off.

This is the format restaurants, plumbers, and chamber of commerce organizations have trusted for years. When you want something budget-friendly, effective, and completely handled from print to mailbox — StuckUp Mailers deliver.

4. Custom EDDM Magnet Mailer — No List, No Problem

The custom EDDM magnet mailer is built for businesses that want to reach an entire neighborhood without the cost or complexity of a targeted mailing list.

EDDM stands for Every Door Direct Mail — a USPS program that delivers your piece to every address on selected carrier routes. No list required. You choose the routes, and the post office handles delivery to every door at rates as low as $0.20 per piece.

MagnetbyMail's Big Ed DM Mailers are designed specifically for this program. They're oversized postcards — significantly larger than standard mailers — with a full-color laminated magnet attached. The larger format takes full advantage of EDDM's size allowances, giving you an impressive canvas that stands out in any mailbox.

Postcard magnet EDDM campaigns work especially well for grand openings, seasonal promotions, and local service businesses targeting a specific radius. If your customer base lives within a few miles of your location, magnet EDDM lets you blanket that area efficiently and affordably. And because there's a magnet involved, that single mailing continues generating impressions long after delivery day.

What's Included in Every MagnetbyMail Order

One of the things that sets MagnetbyMail apart from general printers is the all-in approach to every order. There are no surprise fees for setup, proofing, or mailing preparation.

Every order includes:

Free printing setup. No artwork fees or plate charges hidden in the fine print.

Free digital proof. A proof is emailed to you within 2 business days of submitting your order. You review and approve it before a single piece goes to press — so what you see is exactly what gets mailed.

Free mailing services (on list-based orders). Address validation, inkjet addressing, USPS form processing, and post-office drop-off are all handled at no additional charge. You provide the list; MagnetbyMail handles the rest.

For EDDM orders, finished pieces are shipped directly to you, and you bring them to your local post office — keeping the process simple and giving you control over the timing of your drop.

Who Is Postcard Magnet Printing Right For?

The short answer: any business that depends on local customers.

Restaurants and food delivery use postcard magnets to put their menu on the fridge in every home they mail to. One mailing. Ongoing orders.

Plumbers, HVAC companies, and electricians need their number visible when something goes wrong. A magnet on the wall means they're the first call when an emergency hits.

Real estate agents farm neighborhoods with postcard magnets over time, building name recognition that pays off when homeowners are ready to sell.

Retailers, gyms, and salons use seasonal magnet campaigns to drive traffic and promote offers to households in their immediate area.

Nonprofits running donor campaigns benefit from Non-profit bulk mail postage rates, making postcard magnet printing accessible on even the most limited budget.

If your business has a local audience and a message worth remembering, postcard magnet printing is one of the highest-ROI formats you can choose.

The MagnetbyMail Difference

What makes MagnetbyMail worth trusting with your campaign isn't just the product range — it's the expertise behind it.

MagnetbyMail has spent years working directly with USPS to refine how postcard magnets are produced, assembled, and mailed. Every piece is built to postal standards so it travels cleanly and arrives intact. When you place an order, it goes to an experienced team — not a call center, not an automated system — and that expertise shows in the quality of the finished product.

They also offer free samples so you can hold the product in your hands before you commit. It's a small thing that makes a big difference when you're deciding whether to invest in a new marketing format.
