Url looks suss. Seems kinda sophisticated for the usual ups fishing scam. Here's the text message I got leading here.
"Wishing you a bright and sunny day!"
Lol, I almost want to help this guy by explaining that UPS and American companies in general have disdain for their customers and would never wish them to have anything that would not benefit the company.
USPS will never text you unless you have your account set up that way. My mom sends me these texts asking if they're legit, and I always ask, "Did you order something?" No. "Well, then why would you have a delayed package?"
Again, USPS will not text you like this, and they use a .gov domain.
