Email notificatons

Hi everyone new to this, I have tried to search but couldn't find the result.

I am using a Zyxel VMG1312-T20B

I have successfully managed to add an email account to the router to be able to send log reports. All working well.

What I want to do if possible is just to receive an email when the internet goes down, is this possible and if so how do I set it up? I don't want any other information just that the internet is down and then I can check in on my stuff and make sure the backup router (separate router) has kicked in,

many thanks

Scott
