How works the "following items" functionnality ? - by: dnaton

Hello,

There is a new icon when we are on a ticket, activity, milestone, meeting,....




Could someone tell me how it's work ?

I subscribe to follow a ticket but I don't receive any mails, information when a modification is done on this ticket

What is the difference with the the functionnality that permit to send mail on selected modification present in the menu (Control an Automatism) ?

Thanks
