If you receive an email with EXTERNAL at the beginning of its subject line what do you know about that email...before you even open it?

An email with "EXTERNAL" at the beginning of its subject line indicates that it originated from outside your organization. This serves as a warning to exercise caution, as external emails may contain potential security risks, such as phishing attempts or malware. It prompts the recipient to verify the sender's authenticity and be vigilant about the content before opening any attachments or clicking on links.
