@joelwhrs I will bump this a bit.
Not sure if you figured a way to create custom SMTP triggers, for instance: link goes down, link comes up, no internet, ACL event, etc. I'm also looking for a way to create simple event trigger. From what I understand, all notifications are "fixed", I get one when device is booting or when it finish booting, or cert about to expire. On that note, where to find list of notifications? I just upgraded to 25.07.01.
