We would like to send notification mail whenever user task completes or reassigned to some user. what will be will be best approach to send notification mail.

1. Using Custom Email API project and invoking that API in usertask taskListener(complete,assignment event)
2. create separate process for notify mail functionality, and invoking this process from usertask tasklistener.
