A self-mailer is nothing more than a mail piece that can get mailed without an envelope. (Betcha thought it was a little more complicated than that, huh?)
Well, now that that particular mystery’s been solved, here’s why a self-mailer may be a good idea for your business:
Sometimes it makes more sense to zero in on your particular customer, than to “cast a wide net”. Instead of a magazine or radio ad that can be heard by anyone (most of whom may not be interested in your product/service), you can do a little market research, find the ideal customer for you and mail your ad directly to him/her.
Self-mailers don’t need envelopes. And if you follow the United States Postal Service’s suggestions (conveniently located at www.usps.com), you can save a ton on postage, too!
: A self-mailer can be as large or as small as you want. It can be tri-folded, die-cut, hand-painted... the only limit is your imagination (and the Post Office’s mailing criteria. But trust us, you can do alot). Your potential customers can see a colorful, funky brochure that cuts through the glut of white and brown envelopes that is their mail.
So there you have it. Self-mailers are great for zeroing in on your target market and they have the potential of cutting through the junk mail landscape that inevitably lands on your potential customers’ desks.
