Exercising caution and not rushing must be considered, especially with email messages, even if they contain anti-phishing codes. Although it is a good security measure, it cannot be relied upon entirely. Blind trust in incoming emails is risky because if customer data is leaked or scammers manage to obtain the victim's anti-phishing codes by hacking his device or phishing methods, incoming emails will become like a landmine ready to explode in those who trust them. Scammers and hackers have their own sophisticated special methods, so all security methods must be carefully applied, and the greater the layers of protection and caution, the more protected the user will be.
