It's absurd that you (and others) are getting bombarded with Messages from scammers. There has been an infestation of them here unfortunately, targeting new Sellers as well as seasoned ones. Oftentimes, they appear shortly after someone lists their first item/s. These thieves are using "Verification" as one of their scams, posing as Etsy Staff/Support, etc. When you receive a LEGIT Message from Etsy Support/Staff, etc., it will appear in the "From Etsy" Folder (in Messages). If it isn't there, Mark the Message as Spam (so you don't get dinged for S Seller). *The "From Etsy" Folder is not on the App, however (you must use a browser instead).
Also for future (in case it happens to you), many scammers are posing as "Buyers", stating they need your email for an Order. They don't, Etsy already has it. When you receive a LEGIT Order, it will appear in "Orders & Shipping" (Left Column of Shop Dashboard); if it isn't there, you have no Order. Mark the scammer's Message as Spam (so you don't get dinged for S Seller). And never click on links or engage with them.
Honestly, I don't get why Etsy can't nail these FAKE accounts who are impersonating Etsy Staff/Support, etc. It's happening way too often. Here is the Announcement about the "From Etsy" Folder (currently this is in past Announcements).

Here is the other Announcement "Protect Your Account from Scammers" (it was in past Announcements, but recently has been re-pinned).

Hope this is helpful to you.
