BIMI & your logo in the inbox

BIMI puts your verified logo right next to your name in the inbox — instant recognition and a trust signal. It only works on top of strong authentication, which is exactly the point: it rewards senders who do things right.

What you'll need

  • A sending domain with DMARC at enforcement (p=quarantine or p=reject)
  • Your logo as an SVG (BIMI profile)
  • A Verified Mark Certificate (VMC) for the strongest support

How BIMI works

You publish a BIMI record pointing to your logo, and — for the widest support — a Verified Mark Certificate that proves you own the mark. Climails validates the VMC so you know it's correct before you rely on it.

  • DMARC enforcement is a prerequisite — BIMI won't show without it.
  • The VMC is an X.509 certificate carrying the BIMI indicator; Climails checks its issuer, validity dates and that it's a proper BIMI cert.
  • Supporting inboxes then show your logo next to authenticated mail.

Set it up

  1. 1

    Get DMARC to enforcement

    Move your DMARC policy from p=none to p=quarantine or p=reject once your legitimate mail is passing.

  2. 2

    Publish your logo and VMC

    Add the BIMI DNS record for your SVG logo and, ideally, your VMC.

  3. 3

    Validate in Climails

    Climails verifies the VMC (subject, issuer, validity, BIMI indicator) so you catch problems before inboxes do.

Frequently asked questions

Do I need a VMC?

For the broadest support (including Gmail and Apple), yes — the VMC proves the logo is really yours. Climails validates it for you.

Why isn't my logo showing?

The usual cause is DMARC not at enforcement, or an invalid/expired VMC. Climails' validation points at which one.
