Pony Mail & parcel delivery service

DMM Pony

Pony Mail is the internal mail system for MCPS business mail only.

Place qualified pieces in your school's Pony mailbag. 


aka Nonprofit Rate

You SAVE MORE when your school takes advantage of our FREE BULK RATE postage! All schools are strongly encouraged to use Bulk Rate for mailings of more than 150 pieces.

The Pony picks up Bulk Rate mailings, processes and delivers them to the U.S. Postal Service for you.
Bulk Rate mailings take about the same time as regular mail.

Just put the "SUBURBAN MD PERMIT 201" indicia (postage imprint) on your envelopes. Download the indicia (see below) or request FREE printing of the indicia when you order envelopes for your school from our print shop (EGPS).
The NONPROFIT POSTAGE INDICIA is printed on EGPS envelope orders at no extra charge

TIP: You can use the indicia-printed envelopes for regular mail too. Just put your postage stamp on top of the preprinted nonprofit indicia!

To add the indicia image to plain envelopes, download the required INDICIA and apply it to your envelopes:

No need for stamps. Blue Bag members simply place their mail in a special blue postage bag.

Pay when convenient by JV transfer.
