BIMI email clients: Find out which providers support the protocol
Brand Indicators for Message Identification (BIMI) is an authentication protocol that allows a business with DMARC-compliant domains to display their logo beside emails in the recipient’s inbox. The standard works with DMARC to provide multiple benefits to your organization, including increased brand recognition, awareness, and trust; it also improves email deliverability and reduces the risk of successful phishing and spoofing attacks.
Below, we’ve listed the BIMI email clients that currently support this email-branding authentication standard.

Why BIMI email clients matter
BIMI email clients are helping companies strengthen security and boost brand visibility in email inboxes. The amount of BIMI email clients is increasing, allowing more businesses to enhance their email marketing impact and deliverability.
Implementing the standard shows your organization’s commitment to security and brand integrity. Ensure your company’s domain meets all authentication requirements, including a DMARC policy of p=quarantine or p=reject. Decide whether to get a VMC for full logo and checkmark display or use a CMC where possible for logo display without the verified checkmark.
