An email marketing breach can occur through various means:
Phishing: Attackers trick individuals into providing their login credentials or other sensitive information by posing as a legitimate entity. Malware: Malicious software can infiltrate systems to steal data or compromise email lists. Weak Passwords: Using easily guessable passwords can make it easier for attackers to gain unauthorized access. Insider Threats: Employees or former employees with access to email lists may misuse or steal data.
