Manually sending e-mails
Sometimes, you, as the administrator, may need to send out e-mails containing important messages to a wide audience. For example, if you are planning some maintenance work that will take JIRA offline for an extended period of time, you may want to send an e-mail to all JIRA users to let them know of the outage.
JIRA has a built-in facility, where you can manually send out e-mails to specific groups of users. There are two options when manually sending e-mails—you can either send them based on groups or by projects.
When sending by groups, all you have to do is select one or more groups in JIRA, and all users that belong to the selected groups will receive the e-mail. Users belonging to more than one group will not get duplicated e-mails.
When sending e-mails by projects, you have to first select one or more projects and then the project roles. We will discuss project roles in more detail in the next chapter; for now, you can think of them as groups of users within projects...
