Pony Service

There are two district interoffice pony routes. Delivery of mail to the sites will occur between the hours of 9:15 a.m. and 12:30 p.m. in most cases, every other day.

Due to the ever-increasing volume of mail, the reduction of mail delivery staff, and the weight of the mail bags, the MDUSD mailroom staff requests that you please...


  • Send only two "cums" at a time in the mail bags. Large numbers of "cums" should be delivered to the district office or to the transferring school site.
  • Pony drivers can only carry what fits in the delivery bags.
  • Do not send warehouse "returns" or recyclable toner cartridges through the pony. Call the warehouse for pick-up.
  • Do not use pony to send videos, books, clothing, stuffed animals, toys, etc.
  • Please do not send food items such as candy or cookies through the pony. They may melt or get crushed in the pony bags and/or draw ants.
  • Do not use pony service for personal use such as football pools, Valentine's Day candy, secret pal gifts, etc.
  • Please do not staple pony envelopes closed. Please use tape over the envelope clasps, making sure clasps are flat, or you may rubber band larger bundles. (Staples and clasps cause injuries to the mail staff.)
  • Please use blue or black ink to address pony envelopes. Other colors can be difficult to read.
  • On large mailings going to different site, please bundle and rubber band in alphabetical order by site.
  • Make sure all previous names/departments are crossed out on pony envelopes.
  • Use name and department/site when addressing pony envelopes
  • Denote "elementary," "middle," or "high" when addressing pony envelopes. We have more than one site with the same name; i.e., Mt. Diablo, Sequoia, Pleasant Hill, and Ygnacio Valley.
  • Spell out "Pine Hollow Middle" or Pleasant Hill Middle" instead of "PHM"
  • Give mailroom advance notice of large U.S. mailings.
  • Return extra pony envelopes to mailroom bundled with rubber band, marked "extra."
  • Do not allow business, sales reps or other "outside" groups to use pony service.
Please call the mailroom at ext. 4154 or the Office of General Counsel at ext. 4002 if you have any questions. Thank you for your cooperation!
