Authentication: Ensure your emails are DKIM-verified and check that your SPF records and DMARC settings are correct. Emails are spoofed to present the content within them from some other source or containing information for another topic. To protect from this, DKIM verification is essential. E.g., Gmail uses

Security: By taking a proactive approach and incorporating email security in your company's information technology policy, you will be able to maintain compliance with federal mandates, ensure the security of sensitive data, information is transferred safely, and quality for your mailing list is maintained. This way, when it comes time for an audit, you will be able to prove that all essential safeguards are in place. An email security audit will ensure that your organization is managing its risk appropriately through the use of multi-factor authentication, encryption, and compliance with industry standards.
