BI-FOLD AND TRI-FOLD SELF-MAILERS
A self mailer is a single piece of paper that generally folds and is then sent in the mail. In other words, the mailer mails itself – there is no envelope involved. This type of invitation not only lowers marketing costs but also is able to provide a larger amount of message space than is afforded by a postcard.
Another benefit of this type of mailer is the fact that it does not require an envelope to be opened to view the message contained conveyed within the seminar invitation. Self-Mailers are available in a variety of sizes including 6 x 12 and 8.5 x 12 Tri-Folds and 6 x 8.5 Bi-Folds.
