DigiCert Mark Certificates boost the reputation, engagement and trust of your emails by displaying your logo alongside every authenticated message.
Combined with email authentication standards (BIMI, DMARC), DigiCert Mark Certificates give recipients an instant visual cue that your email is authentic. Choose a Common Mark Certificate (CMC) for trademarks protected by prior use, or a Verified Mark Certificate (VMC) for registered trademarks and government seals. VMCs enable a blue “authenticated” checkmark in Gmail.
