What kind of notification do you get from Fluther, and how do your settings compare to mine (see details)

I hate wasting a question on this, but I can’t find anything that talks about the nuts and bolts of notifications. Specifically, what kind of notification do you get when someone @s you in the answers? Do you get an email? I don’t get anything. My settings look like this.

I verified my email again just now, to make sure Fluther has the right email for me. I don’t get anything when someone @s me. Do you? How?
