On the other hand, if you are unsure about whether it is a phishing email, definitely let us know so we can take a look. As always, be skeptical of emails that ask you to provide personal information, ask you to click on links that require you to provide login/password information, suspicious attachments and links, and other telltale signs of phishing scams.
