If you attach a PDF file to an email encrypted with Virtru, you can optionally watermark it with the recipient email address(es). This can discourage unauthorized sharing and help track who shared a confidential file.  

To watermark a PDF sent in encrypted email:

1. Compose an email.
2. Toggle the Virtru slider to On (if it is not already on).
3. Attach a PDF file to the email. You can use the attach button or drag it onto the compose window.
4. Click the drop-down menu to the left of the Virtru slider and check PDF Watermarking.
   
5. Send your email

The PDF will have an all-over diagonal watermark of the recipient address(es).
