4.Always check for emails that gives a sense of urgency to take a quick action.
And ignore unnecessary emails. To be honest, there is no actual need to do any action with them if they are not of your interest. As long as these emails are random spams, there is nothing to be worried about. Most of the victims of the phishing links and malware mostly are coming from these unsolicited emails. So, if they are not important, ignore or much better block the source of it.
