If you do choose to fold your newsletter, pay attention to how you do so and where your mailing label is placed. Typically, newsletters are creased lengthwise, then folded over width-wise for a smaller mail piece. When folded this way, one side of the mail piece is "closed" (where the fold is) and one side is open. The open side must be tabbed, or closed with a sticker, in order to be "automation compatible," or use postal equipment that allows the lowest possible mailing rate.

Because of the machinery used when the postal service scans the mail piece, if your mailing address is placed so that the open edge of the piece is at the bottom, you will need to place two tabs on the open edge, which makes the newsletter harder to access and thus decreases its readability and increases the risk of damaging the newsletter in the process of opening it. If you simply flip your address around, so that the closed edge of the piece is at the bottom, only one tab will be required to close the folded mail piece, increasing the readability of your newsletter.
