BIMI
BIMI (Brand Indicators for Message Identification) is an email standard that allows brands to display their logo next to their emails in supported email clients. It requires DMARC enforcement at quarantine or reject policy.
Brand Entity (Email)
A brand entity is how AI and search systems identify your brand as a distinct, trustworthy thing with attributes, and a consistent email identity strengthens it.
DKIM (DomainKeys Identified Mail)
DKIM (DomainKeys Identified Mail) is an email authentication method that uses digital signatures to verify that an email was not tampered with during transit and comes from a authorised domain.
DMARC Alignment
DMARC identifier alignment determines whether the domain in the From header matches the domains used in SPF and DKIM authentication. Strict or relaxed.
DMARC Policy Tags
DMARC DNS record tags including v, p, sp, rua, ruf, pct, adkim, aspf, fo, rf, and ri control authentication policy, reporting, and alignment enforcement.
