Why do Email Notification gets skipped occasionally for users?

Question

Certain users often complaint of non-receipt of email notification,

when a jira ticket is assigned to them, they generally get the mail alerts, but for a few instances again when they are assigned a ticket they don't receive emails, These are tickets within the same project, so how can this be removed?

These are also not present in the mail error queue.

Also is it possible to track the same, if a mail is not delivered for any reason that a failure of mail be generated at a later instance?

You also need to go over the exact settings in Jira.  What does the notification scheme say, exactly?  For the "assign" event if we want to debug that.  Does the user always match the mail conditions?  Do they have "email me on my changes" set?

Also, check their spam folders.  Once I've checked the notification schemes, I find 99.99% of "lost" emails are down to users filtering on their client machine, or even just deleting them unread.
