The #10 Envelope: The Classic Envelope for Direct Mail Needs


The #10 envelope is the most common and versatile business mailing envelope.

Chances are, if you’ve picked up mail today, you’ve held a #10 envelope in your hands.

That’s because the #10 envelope is the mainstay of business mailing envelopes. Used in direct mail, billing, and transactional mailings, the #10 envelope can be customized to suit many business needs.

What is a #10 envelope used for?

The #10 envelope is the most common envelope for business mail, including direct response mailings. A #10 envelope fits standard printer size paper of 8 ½” by 11” inches, making it a go-to choice for a wide variety of commercial and nonprofit mailing needs.

Are #10 envelopes used in business response mailings?

Yes. A common way to send business response mailings is to use a #10 envelope and send your business or nonprofit’s call to action along with a pre-addressed #9 envelope inside. In this case, the pre-printed number #9 envelope can either be pre-paid or paid for by the customer.

A mailer including a #10 envelope and a pre-printed business return envelope (BRE) can make it easy for interested customers to respond to you, which results in a higher return rate.

Can a #10 envelope be customized?

Yes. Getting your mailer to your customer is only half the challenge. Customizing your envelope helps get a customer’s attention, and encourages a higher open rate!
