The License Thresholding and Email Notification services are built into the Accusoft Corporation Deployment Licensing Service. This provides the ability to set up e-mail notifications when a set percentage of the licenses are used up in the pool.
When establishing a new license pool with Accusoft Corporation, you can specify whether or not you would like to be notified, and a threshold value (if you have chosen to be notified). You can update your preferences later by contacting Accusoft Corporation.
