Just need to vent

I've been at my current job for more than 2 years. In that time I got married (less than 6 months after I started) so I've had my current name for a good year and a half. And yet, management still can't spell my first name right and still refer to me by my maiden name. And all the management is new since,my name change. It infuriates me when I see it in email memos and such. Like is it that damn hard to learn my name?! It's not even that hard of a name and my new last name is even easier than my maiden!

Am I overreacting? Is this not that big of a deal? Should I say something or let it go?
