My wedding venue has stopped addressing me in correspondence. Am I overreacting to be upset by that?

My fiance and I booked our venue with a shared, wedding specific email hat contains both of our names and contact information and emails were originally addressed to both of us. Last month my MiL secretly got in touch with the venue to ask about food options. The original plan was to cook our own buffet with family, but she wanted to scout out what it would look like to have the venue do food as a gift. This is completely fine with me, btw. She talked about it with us soon after and assured us that she would never make changes without our approval, she just wanted to see what options might be.

The issue is that since she got in touch with them the venue has included her email in all the correspondence (which is mostly fine, I don't really care about her seeing stuff), and has stopped addressing me in said correspondence (which isn't fine to me). So it'll be like:

"Fiance and MiL,

We're hosting a menu testing event and you're invited, etc..."

This really bothers me, as I feel like I'm being pushed out by the venue, even if unintentionally. It's my name on the event, so why am I not addressed in correspondence?

At the same time I feel like I'm maybe overreacting because it literally doesn't change anything - I still get the information and can respond and whatever else I need to do. For context I've also had a bout of health issues and had emergency surgery a couple weeks ago, so I'm restricted in what I'm able to do. Because of that I've been struggling with things that matter being 'taken away' - I *know* I've been more emotional than usual lately. This is also my second marriage and my first one was to an abusive person, so it could easily be that I'm sensitive to being left out of decisions, idk.

So anyway, would that upset you or am I being too sensitive and should just let it go?

Edit: I 100% don't think it was ever intentional, so I'm definitely not upset *at* the venue. I sent an email thanking them for the invitation and requesting to be addressed in the future. It's always an easy fix, I just wanted a sanity check as to whether it should bother me in the first place. Thanks, everyone.
