Question about ArenaNet email
Does it have a link. If it does, it’s not from Anet. Does it have an attachment. If it does. it’s not from Anet.
i usually don’t answer any emails from arena net unless they’re receipts.
There is no way anyone can tell you if it is legit by just looking at the return address. Most of the phishing emails use the same return address as real anet emails as it is very easy to fake.
Take a look at the thread linked below, it should answer your question.
