The primary layers of security in email marketing include:
Authentication: This involves verifying the identity of senders and recipients using protocols like DMARC, SPF, and DKIM. These help in preventing email spoofing and phishing attacks. Encryption: Encrypting emails ensures that the content is accessible only to the intended recipients. This helps protect sensitive information from being intercepted during transmission. Firewall and Anti-virus Software: Implementing robust firewall and anti-virus software can block malicious emails and prevent malware from infecting systems. User Education: Training employees and users about the risks and signs of phishing attacks can significantly reduce the risk of security breaches.
