Let me be clear, mine came to my phone as text messages (not by email) I just read your post again.
Treat it as you would an email from your bank. If you want to donate, go directly to the Trump website (and not thru any link in an email).
Yep - I always delete the texts because I do my donating by actively going to the site I want to use...will NEVER hit a link received in a text.
My wife got a text the other day saying her FedEx package had shipped and it had a link “to track”...she had me look at it and I deleted it but researched to find it’s one of the attempts to distribute some nasty viruses.
