In this chapter, we looked at how JIRA can "stay in touch" with your users with the use of e-mail. With today's new gadgets like smart phones and tablets, being able to keep users up to date via e-mail is a very powerful feature, and JIRA has a very flexible structure in place to define the rules which determine who will receive notifications.
We have also very briefly mentioned some of the security rules surrounding who can receive notifications. JIRA performs security checks prior to sending out notifications for two very good reasons: one, there is no point sending out an e-mail to a user who cannot view the issue, and two, you will not want users not authorized to view the issue to receive updates that they should not know about.
In the next chapter, we will look into the security aspects of JIRA and how you can secure your data to prevent unauthorized access.
