BIMI (Brand Indicators for Message Identification) is a standard that lets your brand logo appear next to your messages in supporting inboxes. It is published as a DNS TXT record pointing at your logo.
BIMI is a reward layer, not a deliverability tool: it only works once SPF, DKIM, and an enforced DMARC policy (quarantine or reject) are already in place, and some inboxes also require a verified mark certificate.
See the full guide: Related: the authentication guide.

Frequently asked questions
Does BIMI improve deliverability?
Not directly. BIMI displays your logo on already-authenticated mail; it requires an enforced DMARC policy and does not replace SPF or DKIM.
