CUSU Mail Service (CUSU-MS)

CUSU operates a free mail service for students and societies to send post between all 31 Cambridge University colleges.

This free service is funded by relevant flyer and poster advertising which is also distributed alongside student mail. We are so grateful to the companies that choose to advertise with us. Their support makes it possible for this free service to continue.

Frequently asked questions…

Please mark your envelope "CUSU-MS" and clearly write the name and college of the recipient.
Please put the envelope in the CUSU-MS box at your college. This may be a post box, a pigeon hole, or a designated area at the Porters' Lodge
Deliveries are made 3x per week (Weds/Thurs/Fri) during term time CUSU aims to collect and deliver all mail within 2 working days (term time only). Please note that mail posted on Fridays may not be delivered until Wednesday of the following week.CUSU has just one Mail Service Coordinator so it is occasionally the case that there may be a delay in delivery due to unforeseen absence. We will always endeavour to update your college in the event of any circumstances that may cause a delay in delivery and always take steps to ensure the mail service resumes usual service as soon as possible.
We deliver to all 31 Cambridge University colleges, CUSU and The Graduate Union Please note: the CUSU-MS does not deliver to University departments.
CUSU post will be delivered to the Porters at your college. The Porters will distribute the mail into the relevant pigeon holes for collection.
The CUSU Mail Service is completely free for students who wish to send up to 30 letters at once. To ensure we can continue our free mail service we make a small charge of 25p for each item over the 30 item limit. Bulk mailings (of 30 or more) must be dropped off at the CUSU offices (17 Mill Lane) for despatch, along with a cheque made out to Cambridge University Students' Union.

The CUSU Mail Service is managed from the CUSU offices at 17 Mill Lane. Please contact our Fundraising and Business team here if you have a question regarding the service.
