Hello I just got an email from Adobe about a full Subscription I never did and checking on my app it shows I'm a free user.......the email looks genuine so just a mistake or some scam?
looks fake because reader is free and no subscription (free or otherwise) is needed. just go to your app store and install acrobat reader on your mobile.
you have to examine the email headers and i'm not sure that's possible with your email program on a mobile. anyway, don't click anything from that email, or at least, don't give any personal info.
Looking at an email address tells you nothing. It's like reading the name at the bottom of a letter; no proof of anything. Because ANYONE can send email from ANY address. The email header, if you can see it, gives a trace of the servers it came from, and carefully reading the whole chain (NOT being selective) can tell you things, but it's hard.
