Emails have become one of the most ubiquitous communication tools in today's world. Businesses and individuals rely on emails to send and receive information around the world almost instantly. Therefore, it should come as no surprise that Jira is fully equipped and integrated with email support.

Jira's email support comes in several flavors. First, Jira sends emails to users about changes that have been made to their issues, such as adding comments, so people working on the same issue can be kept on the same page. Second, Jira can also poll mailboxes for emails and create issues and comments based on the content of the email. The last feature is the ability for users to create and subscribe to filters to set up feeds in Jira (we will discuss filters in Chapter 10, Searching, Reporting, and Analysis). These features open up a whole new dimension on how users can interact with Jira.
