Secure/Large Email Attachments

Pepperdine Secure Email Attachments


Pepperdine University's secure attachment service allows you to send encrypted attachments. This service is useful for sending very large files, up to 20 GB per message.

Pepperdine students, faculty, and staff can use the system to send attachments to other Pepperdine community members as well as to recipients outside of the university.

Best Practices and Benefits

  • Attachments are encrypted. This is required by University policy when transmitting RESTRICTED information.
  • The body of the message is not encrypted; do not place RESTRICTED information in the body of the message.
  • File attachments sent through this system do not count against Google email attachment size limits.
  • Attachments are accessed by a hyperlinked button in the email message for the recipient to download.
  • Download links that expire are securely deleted from the system.
  • Attachments are only available for download for fourteen (14) days.

 Send Secure Email Attachments

The Pepperdine Secure Email Attachments system, also called "Attachments" for short, is available to all students, faculty, and staff who have an "" email address to send large and secure email attachments. NOTE: when "Secure access" is set, a non-Pepperdine recipient will be prompted to create an account when they attempt to access files.

      • Secure access - We recommend that this is left checked for maximum security. When unchecked, the recipient will not need to log into the secure attachments service to download the file and you will not be able to receive any notification when the recipient downloads the file.
        If sending RESTRICTED information, the box should remain checked (secure) so that a password is required and you can receive a notification when downloaded.
      • Notify me when files are downloaded - When selected, you will receive an email notification when a recipient downloads the file. You can also add other individuals (to receive these download notifications) in the "Also notify" box.

  9. Click "Add Files" and select an upload option

 Request Confidential Files

If you require a sender to email you a file with RESTRICTED information, perhaps the easiest way is the "Request File" option in attachments as instructed below.

Alternatively, if you require a non-Pepperdine sender to email you RESTRICTED information on a regular basis, simply send a message without an attachment and invite the recipient to Sign in using their email address to create a guest account on the secure email attachments service. After that, they can Send Secure Email Attachments to you.
