Frequently asked questions.
What is BIMI?
Brand Indicators for Message Identification displays your logo next to authenticated emails in supporting inboxes, boosting trust and open rates.
Do I need a VMC?
Gmail and some providers require a Verified Mark Certificate to display your BIMI logo. Others will show it with just the record.
Why isn't my logo showing up in Gmail?
BIMI only displays when your DMARC policy is at enforcement (p=quarantine or p=reject) — with p=none, most providers will hide your logo.
What format does my logo need to be?
BIMI requires an SVG Tiny PS logo — a restricted SVG profile, not a regular SVG export from most design tools.
Does BIMI work without SPF or DKIM?
No — BIMI depends on DMARC, which itself requires SPF or DKIM alignment. Without those, your BIMI record won't have any effect.
Which email providers support BIMI?
Gmail, Yahoo, Apple Mail, and Fastmail are among the major providers currently supporting BIMI, with more rolling out support over time.
