technical issue Pop up notifications stopped

[Unity 332]

Now I'm not sure if this is roblem with my email notifications or not, but before a few days ago I used to get emails when someone would respond to a topic of mine, or if somepony reacted to one of my comments. Do pretty much I would get a notification through my email and through these forums on the notifications tab. But now I don't get emails anymore. I went to the notification settings and changed a few things, but still no emails.
