Capture Your Reader's Attention

Your envelope’s appearance has a big impact on your direct mailing’s response rates. If the envelope looks appealing or arouses curiosity, the more likely it is to be opened and the contents read. Otherwise the whole mailing may be discarded, unopened and unread.

A Zip Strip involvement device opens effortlessly. The zipper-like opening pulls back with ease. And it can go almost anywhere: top or bottom, back or front, left or right. The pull tab is easily recognizable and simple to grasp.

Direct mail best practices tell us that you typically have three seconds before the recipient puts your envelope in the recycle, and 30 seconds to engage the reader enough to get your envelope opened and make the short stack for later reading. A quick pull on a Zip Strip allows quick access to the envelope’s contents. It gives almost immediate gratification to the question of what’s inside the envelope.

Tailor Your Message

Including a message like “Pull to reveal your special offer” piques the addressee’s curiosity. It also allows you to leverage variable printing on your insert so that offers can be uniquely tailored to the recipient or customer segment.

Even the best offers and most powerful copy can erode from overexposure. When this happens, a new design or unique envelope can help restore levels of response. Use a Zip Strip to capture your reader’s attention. It’s so inviting, they’ve got the envelope open before they know it.

What Tension Customers are Saying

I was having problems finding a dependable supplier for blank 8.5x11 forms with a single perforation. When my sales rep at Tension learned about this issue he developed a solution, getting the paper I needed and stocking it at the warehouse. Now instead of waiting a week to get stock in, I can have the forms I need delivered the next day from Tension.
