Spam Messages Versus Phishing
While both spam and phishing result in receiving unwanted messages, spam is generally not harmful while phishing actively targets the recipient with the goal of stealing login credentials or sensitive data. Spam messages are typically unsolicited commercial emails (e.g. advertisements). There is no need to report spam email messages to Technology Services unless you think it may be malicious.
