In a digital world overflowing with unread emails, physical mail demands attention. Adding a tip-on promotional product—a physical gift temporarily attached to a mailer with a glue dot—transforms ordinary correspondence into a high-response marketing vehicle. This strategy gives recipients a tangible reason to engage with your brand.
In the example above, The University of Wisconsin Foundation sent donors a branded paperboard coaster as a reminder for their upcoming giving day, "The Day of the Badger." Small incentives like this can also invoke the rule of reciprocity in donors, where psychologically recipients are more likely to feel compelled to return the favor of a gift with a monetary donation. It's why so many non-profit campaigns include a set of personalized return address labels in their mail packages.
First impressions matter, but in direct mail, the second impression seals the deal. Tip-on promotional products act as the ultimate icebreaker, giving your target audience a functional, multi-sensory experience before they even read your pitch. This mailer included a package of Pop Rocks candy to emphasize the mailer's message: "Make Your Marketing Pop!"
Stickers and decals can make great tip-ons for a direct mail piece. They are lightweight and fit easily into an envelope or self-mailer.
You can do custom die-cut decals inserted individually, or an entire sheet of branded stickers. If your brand has a related scent, you can even do scratch-and-sniff custom scented stickers to engage the senses!
Other sticker examples we have seen include keyboard stickers to dress up a laptop, car decals/window stickers to show alumni pride, or a set of calendar stickers to "save the date" for fundraising events.
Speaking of events, temporary tattoos can make a great tip on for grand openings, sporting events or fundraisers. Recipients can wear your brand on their body with pride for multiple impressions.
Magnets are another great tip-on for direct mail. Most people have magnets on their fridges all year long, and frequently see them as they grab food or hang up important documents for later. Just keep in mind that the United States Postal Service (USPS) sent out a revised ruling in November 2025 about magnets in mail, so be sure to follow their guidelines.
Want to instantly boost your direct mail response rates? Stop sending flat paper. Tip-on promotional products add texture, weight, and immediate utility to your mailers, forcing recipients to pause and interact with them. Adding a simple physical gift can maximize your return on investment and turn cold leads into loyal customers.
