Sending Secure Encrypted Email

How to Send Secure Encrypted Email 

The SOM policy for the Acceptable use of Email and Confidential Data states Email containing confidential information such as PHI, PII, or client credit card information must be encrypted when sent to an external recipient.  An external recipient is any recipient who does not have an email address of any variation (e.g. @som) ending in "" or "".  

To send an encrypted message off campus

Add the word "[secure]" at the beginning of the subject line of the email as shown below.  Be sure to include the brackets but do not include the quote marks. There must be a space after the brackets.  Putting the word [secure] anywhere else in the subject line will not encrypt the message.


When you have completed the email and added any necessary attachments, click the "Send" button.
