Check BIMI record and logo

Check a domain's BIMI record: logo address, SVG file, certificate and the DMARC enforcement it requires. With explanations.

What the BIMI checker checks

BIMI shows your logo next to your emails. The checker reads the record at default._bimi and checks what mailboxes require:

  • Record: v=BIMI1; l=https://…/logo.svg; a=https://…/certificate.pem. The l points to the logo, the a to the certificate.
  • Logo: an SVG file (SVG Tiny PS) under 32 KB, without scripts and embedded images, available via https.
  • DMARC: BIMI shows the logo only with p=quarantine or p=reject for all emails.
  • Certificate: Many mailboxes, including Gmail, require a VMC or CMC. We only check whether an address is given, not the certificate itself.

Whether a mailbox finally shows the logo is up to each mailbox. Check DMARC

FAQ

What is BIMI?

BIMI shows your logo next to your emails in the recipient's mailbox. For this you publish a record at default._bimi in DNS that points to your logo as an SVG file.

What do I need for BIMI?

DMARC with p=quarantine or p=reject for all emails, a logo as SVG Tiny PS and, for many mailboxes including Gmail, a certificate (VMC or CMC) issued for the domain and the logo.

Why is my logo not shown although everything is right?

Each mailbox decides for itself. Often the certificate is missing, or the domain does not yet send enough emails with a good reputation. The checker shows you what is missing in the record and the logo.
