I want to receive an email notification when a particular user in my discourse forum makes a posts. I currently have it set to “follow” them, but I am not getting emails when they make posts.
Hello and welcome @proot 
Have you ticked the box on your Preferences/Notifications page?
[YourSite]/my/preferences/notifications
(and it might be worth checking your Preferences/Emails settings too 
)
Edit:
Having said that, I now can’t remember if I’ve ever received an email for a Follow notification. 
I shall go and test.
Update: It does not look like that is a notification that triggers an email.
Hopefully someone will correct me if I’m mistaken…
That’s what I initially thought, but I set both to ‘Always’ and Followed a test user to check. I got the notification of when they posted, but no email. And no email was sent or skipped. I may have fluffed the test somehow.
@JammyDodger, I have the same experience as you. I am not receiving emails when someone I am watching makes a post, including when I have the preference Jay mentioned set to Always.
I’ve tried it again a few times, and I’m not getting an email generated for that notification. 
Pretty sure email notifications aren’t implemented in the Plugin yet.
Suggest you post on the Plugin Topic.
Is there a way to send out an email to all users when a specific user posts a thread?
I have an RSS feed setup to a moderator account and I want that to also email the forum users.
