On occasion, there may be a need for a Jira Administrator to notify users of any event that will be happening on the site. For example, maintenance notification, rebuilding index, upgrade or even a planned outage.

環境

Jira Server/Data center on any version from 8.0.0.

ソリューション

Notes about the solutions below: while there is no limitation on the Jira application side to send a high number of notifications at once, the SMTP server used by the Jira application might have some throttling limit. Therefore, we recommend reaching out to your SMTP Mail Server administrator before using the solutions below, to make sure that the mail server can handle a high load of emails in a short period of time.

ソリューション 1

You can use Jira's Send E-mail feature, but to access this feature, you need to have Jira Administrator global permission on the Jira application.

Navigate to > System > Mail > Send E-mail page, and you can draft a message to the list of Groups or Project Roles you want to send the email to as illustrated below:

ソリューション 2

In the event of a Jira outage and you would like to send a notification email to all the users, you can retrieve the list of emails through Jira database:

 SELECT DISTINCT email_address FROM cwd_user;

You can then send the email to the list of addresses generated from that query.  However, If you wish to fetch all the user and their email addresses based on the application (Jira Core, Jira Software, Jira Service Management), you may refer the document Get list of licensed users in Jira server 

ソリューション 3

You can use the Announcement Banner to inform any information or activity happening in the instance: Configuring an Announcement Banner.
