Is your domain ready for BIMI?
Our BIMI Checker and DMARC validation tool verifies whether your domain is configured to meet the requirements for BIMI (Brand Indicators for Message Identification). It checks your published BIMI record, DMARC records, whether a CMC or VMC certificate is found, and whether a logo is found. This allows you to quickly identify configuration issues that may prevent your brand logo from displaying in supported inboxes.
To use the tool, enter the domain you send emails from in the form below. We'll validate whether your BIMI configuration is in place and provide clear guidance on fixing any issues.
BIMI requirements FAQ
BIMI requires several components to work together. Your domain must have SPF and DKIM authentication in place, an enforced DMARC policy (p=quarantine or p=reject), and a properly configured BIMI DNS record before your logo can appear in supported inboxes.
Answers to common questions about BIMI requirements, setup, and logo display can be found below.
BIMI (Brand Indicators for Message Identification) is an email standard that lets organizations display their logo next to authenticated emails in supporting inboxes. It builds on existing email authentication—SPF, DKIM, and DMARC—so a strong DMARC policy is a prerequisite, not an alternative.
What’s next after my domain passes validation?
If our tool confirms that your BIMI record, DMARC policy, logo, and mark certificate are all properly configured, no further setup should be required. From there, allow time for any DNS changes to propagate and for supporting mailbox providers to begin displaying your company logo next to your emails.
If the tool indicates that you still need a Verified Mark Certificate or Common Mark Certificate, Sectigo is a trusted provider that can help you obtain the certificate required to complete your BIMI setup.
