Part of the goal of any mailing is to first inspire people to open it and second to get them to interact with it long enough to make an impact. This is generally done with things like a great message, creative graphics, and textured paper.
But imagine if you were holding an envelope that had a bunch of bumpy things in it. You’d probably be more likely to open it, wouldn’t you?
Sending an easy to put together puzzle is a great way to grab attention! People are more likely to open it because of the different feel of the envelope and they can’t help but put the puzzle together to see what it says. They have fun – which means they have a positive feeling about you and your organization – and they absorb your message because they are spending time with it.
