If the sender or address is unfamiliar, or the content is unrelated to anything you are expecting, it is best not to open the message. It is highly unlikely that you could win a prize in a contest you didn’t enter, so be wary of any emails claiming that you won something. If the email subject appears to be related to something you are anticipating, it is important to thoroughly examine all aspects of the message. Scammers often make mistakes, so carefully scrutinizing the content of the email could help you identify any fraudulent activity. Remember, it is always better to err on the side of caution and avoid opening emails or letters that appear suspicious.
