Answers to common questions about BIMI records, logo requirements, and mailbox support.
BIMI is a standard that lets mailbox providers show a brand logo beside authenticated email. It depends on strong DMARC enforcement and a valid BIMI DNS record.
Yes. BIMI requires a DMARC policy at enforcement, usually quarantine or reject, and the domain needs passing aligned authentication before mailbox providers will consider showing the logo.
Many major mailbox providers require a Verified Mark Certificate or similar certificate before they display a BIMI logo. Some environments support self asserted BIMI, but certificate backed BIMI is more broadly useful.
Common causes include DMARC not being enforced, an invalid SVG, a missing or invalid certificate, DNS mistakes, mailbox provider caching, or sending to a provider that does not support BIMI.
No. BIMI is a brand display layer. It relies on SPF, DKIM, and DMARC to prove that the message is authenticated before a logo can be shown.
