u/ASH_247

First, I'm not an apple user and know very little. I have an account because for a brief time I used my husband's old iPhone. Anyway, I got an email saying I my account had signed in to an iphone 6s plus. Email looks legit with my name and not 'dear customer,' and the sender is noreply@ email .apple .com (spaces added to avoid linking). I received another email about changes to my account a few days later. When I go to the website login ttps://support.apple.com/apple-account it says I don't have an account, which I'd just disregard everything if I didn't have an account saved in my browser passwords. That has to mean I have or at least had an account. What in the world is going on? Are these phishing emails I can ignore or do I have something serious on my hands?
