Promotional Mailers | Self Mailers | Continuous Multiple Part Mailers

There are many different types of mailers and each type of mailer is available in a variety of sizes and styles. The mailer's size limitations will depend on how it is manufactured and the size requirements of the equipment used to imprint and personalize the mailer.

Promotional Mailers

Promotional mailers can be many different styles and sizes. They can be a single sheet folded once or multiple times. They can also consist of multiple sheets folded together. The only size limitations would be the minimum and maximum mailing sizes set up by the United States Postal Service for the type of mailing being used for the mailer. See the Postal Regulations - Outgoing Mail.

Note: The finished folded size of the mailer is what needs to meet the minimum and maximum mailing size requirements.

Self Mailers

Self mailers can be manufactured as a one part continuous or a single cut sheet product. Each will have different limitations which are affected by the manufacturing and imprinting process. Mailers manufactured as a continuous product will have to follow the same size guidelines as you would on a continuous form. See Continuous - Size for more details. Cut sheet mailers that will be processed through a laser printer will have to follow the same size guidelines as you would for laser forms. See Laser - Size.
