Self-tab Mailers: A letter size page is folded in half (Bi-fold), into thirds (Tri-fold), or a legal size page into 4 sections (Quad-fold) to create 3 different sizes offered as self-tab mailers.The mailing panel takes the place of the face of an envelope. It is the portion of the design that contains the return address, mailing address of the recipient, and postage. The mailing panel typically appears on one-half (folded letter size, for example), one-third (a tri-fold), or one-fourth (a quad-fold) of the back page so that it faces out when folded. Round, transparent stickers, “Tabs” are used to seal the piece for mailing. This style of mailing offers some cost savings by eliminating an envelope and possibly postage costs, but lacks the professional look of the enveloped options that we have to offer, and does not have the option to include tickets, another tool that we have seen to add a meetings success.
