So I think someone essentially sent me a "text" but to my e-mail. The sender is phonenumber@mms.att.net. I don't recognize the number, but the text/e-mail says:

"Any chance of u 3 coming by this weekend for lunch or supper?"

So it definitely seems like it could be someone that knows me. The area code is MA and we do have both friends and family that live there. Should I respond at all with "Who is this?" or just ignore it?
