Strange Emails

Recently i have been receiving the same email repeatedly. Everything appears to be from blizzard, but it still looks very suspicious. Is this a real E-mail? And if it is real, what is changing in my account? I can still log in and nothing looks to be changed in either personal information or billing information. Also, i have an authenticator.
