The Postal Service wants employees to always exercise caution when sending emails internally and outside the organization.
Employees should only send sensitive information, such as business financial data, or sensitive-enhanced information, such as Social Security numbers, to those with a need to know.
Before emailing USPS information to external recipients, the CyberSafe at USPS team advises employees to consider the following:
• Does the recipient need to know the information? If you’re unsure, ask your supervisor.
• Is the email address correct? Before sending, double check all addresses to make sure the message will be sent to the correct recipients.
• Did you encrypt the email? Include #sensitive# in the subject line to activate the Enterprise Encryption Service, which automatically encrypts the email’s contents.
