Interoffice Mail
Penn Mail Services uses reusable envelopes for interoffice (intramural) deliveries. To support Penn's Climate and Sustainability Action Plan and help contain expenses, Schools and Centers are asked to reuse the many gray envelopes currently in circulation.
When using gray interoffice envelopes:
- Cross out all previous addresses on the envelope.
- Write the intended address in one of the 18 printed address boxes.
- Leave the envelope in your outgoing mailbox for pickup.
Penn Mail Services will also pick up surplus gray envelopes for recycling at no cost with your outgoing mail. Supplies of returned recycled envelopes have dwindled, so Schools and Centers are encouraged to make unused envelopes available for pickup and reuse.
If you're interested in purchasing interoffice envelopes, please do so through the Penn Marketplace.
White intramural mail envelopes used for confidential messaging remain available for purchase from Mail Services in boxes of 200 for $165. Pricing is subject to change. Email your order to mailservices@upenn.edu.
