Permit Mail and Large Mailings
Permit Mail, otherwise known as permit imprint, is the most convenient way to reduce postage costs when sending out large mailings. Instead of using a meter to apply postage, the stamp or "Indicia" is preprinted on the envelope. Permit Mail must be prepared according to USPS guidelines in order to receive postage discounts.
Bulk Mail is generally the term used to describe large mailings. Bulk mail requires minimum quantities of mail to be prepared for a specific class of mail in order to qualify for postage discounts. For instance, First- Class mail requires a minimum or 500 pieces while non-profit mail requires 200 pieces to qualify for discounts.
Use of a letter shop or direct mail vendor is required to ensure mail is prepared and presorted according to USPS guidelines.
Stamped or metered mail greater than 500 pieces is not considered bulk mail.
Obtaining a Permit
Penn Mail Service maintains a permit for the use of nonprofit organizations directly affiliated with Penn for mailings of a minimum of 500 pieces. (Smaller mailings must use a MAC card). Departments may not authorize the use of the University's mailing permits nor make deposits into the permit accounts. All requests must contain the following information:
- Department initiating the mailing
- Expected date of mailing
- Approximate number of pieces
- Description of the mailing
- The firm handling the job
- A department budget code
- A contact name and phone number within the department
