"Why won't the Post Office accept my Self Mailer that way?"

There are times that a design element causes a mailing to go at a higher rate of postage or be refused for mailing completely. This can be frustrating as well as costly. One of our core services is to review your design to verify that it meets USPS mailing specifications and requirements. Our mailing experts have over 30 years of experience working with the Post Office and will assist you in avoiding the pitfalls of mail piece design.

Here are some simplified design guidelines for several standard mail piece types.
