The #9 envelope is designed to fit folded letter-sized paper. This makes them a perfect choice for many regular business mailing applications. However, they also have a special role to play in pre-printed business reply mail. That’s because the business response envelope (BRE) is one of the most popular envelope sizes for commercial mailings. They are often used in direct mail campaigns, sent out nested within a larger envelope. When pre-printed with your company’s mailing address, the #9 envelope makes it easy for customers to respond, donate, or return payment.

Who uses a #9 envelope?

Any business that wants to encourage a higher customer response rate can make use of the #9 envelope for a BRE. Commonly invoices, donations and other business requests are included in the original mailing and returned using a pre-printed #9 BRE. This makes returning information much easier for your customer. The #9 envelopes are machine-insertable, which facilitates efficient high-volume direct mail.
