Recently (as in the last month), I have been receiving email notifications whenever someone adds me to a Trello board. These emails are not necessary, I always instantly delete them. I'd rather stick to the in-site notifications that I receive for being invited to a board, instead of the email.
The email has no unsubscribe link in it. Moreover, there don't appear to be any settings on my Trello profile to disable this. I already have my Email Notifications settings set to "Never". How do I disable these emails then? Is this just unimplemented behaviour?
