Configure Email Options
Global default values for specific email related settings
Max Events per email - How many events an email should contain, an event is one action, e.g. one ISSUE_CREATE and ISSUE_COMMENTED equal 2 events.
Emails per Flush per Recipient - How many emails should a recipient get per flush. This metric comes into play when either (a) the Max Events per Email is low enough to not satisfy the generation of events, or (b) attachments are enabled and have exceeded total limits for the email. Where emails are not flushed 'this time' subject to all events fitting into the flush window 'next time' they will be sent later. Reducing the overall duration between notifications will reduce the likelihood of this scenario.
