Email Standards

DMARC (Domain-based Message Authentication, Reporting and Conformance) – is an email authentication protocol. It is designed to give domain owners the ability to protect their domain from unauthorised use. The purpose of DMARC is to protect a domain from being used in business email compromise attacks, phishing emails, email scams and cyber threat activities. In combination with SPF and DKIM, DM ARC provides comprehensive email security  that will substantially increase your protection against high- risk email. 

DKIM DKIM stands for DomainKeys Identified Mail. This is an email authentication method that allows the recipient to verify that an email was sent from the domain it claims to be from and that it has not been tampered with during transit. DKIM works by attaching a digital signature to the header of an email message. 

SPF (Sender Policy Framework) is an email authentication method designed to detect forging sender addresses during the delivery of the email.

It increases brand recall, improves email open rates, and influences buyer behavior by putting a trademarked logo next to every email you send with the only integrated BIMI and VMC integration available on the market. 

VMC (Verified Mark Certificate) – is a digital certificate issued by a certificate authority that verifies logo ownership. Your logo must be a registered trademark before receiving a VMC. A VMC verifies that your organization is the legal owner of your brand logo. (Source:
