When I go through my mail, I know immediately if I'm going to open an envelope. I can spot a piece of junk mail as soon as I open my mailbox—and it usually goes directly in the trash. If you use direct mail to communicate with your customers, clients and prospects, don't let this happen to you.
According the Duct Tape Marketing Blog, getting people to open your envelope is half the battle. The blog offers two guidelines for making sure this happens:
•When sending a letter to a group of existing clients, hint about what's inside on the envelope.
•When sending an offer to a list of suspects who don't know you, use a little mystery, making the envelope as simple as possible (plain with just a return address), so prospects will be curious about the contests inside. Don't disguise the letter as something official that must be opened. Such trickery will only anger those that you want to impress.
Overall, the blog points out, being trustworthy—even down to your envelope—is the best way to get your mail opened.
