New Year, New Service is 'Critical' (Mail)

The New Year will bring good news for Priority Mail Commercial Plus customers — a brand new product called Critical Mail.

This new offering is an attractive marketing tool that will help companies and organizations attract and retain customers.

All Critical Mail envelopes must be automation compatible, which means letters cannot exceed 3 ounces or ¼ of an inch thickness and flats cannot exceed 13 ounces or ¾ of an inch thickness. Mail is charged one price across all destination zones regardless of weight — $3.50 for letters and $4.25 for larger flat-sized envelopes. Optional electronic Delivery Confirmation service is included for free.

To qualify, customers must have a customer commitment agreement with the Postal Service and mail 5,000 or more Critical Mail letters and/or flats during a calendar year. USPS-produced Critical Mail envelopes, which have an attractive design that drives an “open-first” behavior, must be used. The envelopes are available to authorized customers only by calling USPS Expedited Packaging Supplies at 1-800-610-8734.
