What is BIMI?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
BIMI (Brand Indicators for Message Identification) lets you display your logo next to your emails in supported inboxes. Instead of a generic initial or blank icon, recipients see your actual brand mark in Gmail, Apple Mail, Yahoo, and a growing number of others.
It exists because of a trust problem: people struggle to tell legitimate email apart from spoofed lookalikes. A verified logo in the inbox gives visual confirmation that the sender is who they say they are. It's an anti-phishing signal and a brand visibility benefit in one.
Getting BIMI working requires four things. First, DMARC at enforcement level (p=reject or p=quarantine). This is the hard prerequisite most senders haven't reached yet. Second, a properly formatted SVG logo file hosted at a specific path. Third, a BIMI DNS record pointing to that file. Fourth, for Gmail specifically, a certificate, a Verified Mark Certificate (VMC) or a Common Mark Certificate (CMC), from a certificate authority. As of November 2026, the BIMI Group list names DigiCert, GlobalSign and SSL.com. Each mailbox chooses, so check before you buy.
A VMC adds cost, which is why BIMI adoption is mostly concentrated among larger brands. As of November 2026, a VMC runs roughly $750 to $1,750 a year, depending on the authority, reseller and term. A CMC is usually a bit less. A VMC also needs a registered trademark, a separate cost. This is a guide only, so ask for a current quote. Yahoo says it does not currently require a VMC, and it shows logos only on bulk mail with good reputation and engagement. Apple Mail can show a BIMI logo on macOS Ventura 13, iOS 16, iPadOS 16 or later, when the mail provider supports BIMI, is verified by Apple, and verifies evidence such as a VMC.
If you're not at DMARC enforcement yet, that's the step to take first. You can check your current DMARC policy with the free DMARC Checker. If you're already at enforcement, BIMI for Yahoo is within reach, and Apple Mail depends on your mail provider. And the Gmail VMC is worth the investment if your audience is Gmail-heavy.
