The options for which notification get send or do not get sent to my email are very limited. One is “All activity.” Obviously, I have to have this on, because if a coworker responds to a thread I am following, I generally need to know and often need to respond. A response from a coworker is real activity. By contrast, if someone simply “likes” a comment I made, that’s not real activity in the same way. I don’t need another email telling me about a “like.” Clearly, this feature is for insecure users who need frequent reassurance about whether they’re liked. There definitely should be a way to turn off email notifications for “likes” without turning it off for “all activity.”
