Are email attachments private?

Not really. Standard email attachments have several privacy issues.

Problems:

  • Attachments aren’t encrypted (even with secure email, sometimes)
  • They’re stored on multiple servers
  • Recipients can forward them anywhere
  • Files contain metadata (your name, location, edit history)

Before sending sensitive files:

  • Use encrypted file sharing instead of attachments
  • Password-protect sensitive documents
  • Strip metadata from files before sending
  • Consider if email is the right way to share

Better alternatives:

  • Encrypted cloud storage with share links
  • Secure file transfer services
  • End-to-end encrypted messaging for small files

Assume any attachment you send could be seen by others or forwarded endlessly.
