Hey! So I called and they said my application is awaiting a decision Since June 7, after doc received June 5. I told him about the email I got, and he thinks it isn't spam and they sent it for a reason. He said they Could've actually sent it to UKVI NY to review a section or info about me. Also, he told me to contact VFS about the return Shipping Waybill to see what to do if it is actually now sent in New York. They might end up adjusting it to send my documents back to me. Doesn't sound like terrible news so far.
Otherwise he said to wait and see if they email you if they need extra information.
