Head’s up, Letter senders! With the Christmas and New Year holidays around the corner, we wanted to inform you of the Holiday base mailroom closures and the shipping deadlines for Sandboxx letters. Below you’ll find the recommended deadlines for each base to ensure that your letter gets to base in time for the holidays.
It’s common for unexpected delays to occur due to staff shortages, higher than normal mailroom volume and other unforeseen complications or errors. It’s important to send your letters sooner rather than later.
Note: this schedule is subject to change, but is based on the latest information that has been provided to us by the mailrooms on base.
Happy Letter Writing.
