Employees who improperly send emails can undermine the security of Postal Service information systems.
As part of National Cyber Security Awareness Month, the CyberSafe at USPS team offers these tips:
- Limit personal use of Postal Service email accounts.
- When you send emails that contain sensitive information outside USPS, encrypt the information by typing #SENSITIVE# in the subject line. This will secure the email content and attachments.
- When you email sensitive messages within the Postal Service, use password-protected WinZip files to encrypt the information.
- Don’t use USPS devices — including computers, smartphones and tablets — to check personal email accounts or social media sites.
- Don’t forward Postal Service emails containing sensitive information to personal email accounts.
- Don’t open emails from individuals or companies you don’t know or recognize.
- Don’t “reply all” to emails with lengthy recipient lists unless necessary.
- Don’t use personal electronic devices to receive, process, store or send emails that contain sensitive Postal Service information.
If you receive a suspicious email, send it to cybersafe@usps.gov.
