Verify That Your BIMI Record Is Functioning Properly

Reaching the BIMI stage means you've likely already implemented SPF, DKIM, and enforced DMARC - well done!

Whether you've already published a BIMI record or are still in the process, DMARCFlow's BIMI checker provides valuable insights. After entering your domain, it pulls the BIMI record from your DNS, validates the logo and VMC, and shows a preview of how the logo appears in various contexts. If anything is missing or misconfigured, the tool highlights the issue and offers clear guidance to resolve it.

Frequently Asked Questions

Common questions about BIMI

BIMI stands for Brand Indicators for Message Identification. It's a standard that allows your brand's logo to appear alongside authenticated emails in supported inboxes, making your messages easily recognizable and trustworthy.

BIMI works by adding a special record to your domain's DNS, which includes a secure link to your logo and optionally a Verified Mark Certificate (VMC). When an email is sent, supported providers check your DMARC policy and BIMI record. If both validate, your logo is displayed next to your emails.

You need an enforced DMARC policy (quarantine or reject), a logo in SVG format hosted on a secure URL, a VMC (if required by the provider), and a BIMI record published in your DNS.

BIMI strengthens your brand's presence in inboxes by displaying your official logo, reinforcing trust and authenticity. It also shows you're committed to email security and protecting your domain from impersonation.

Yes, BIMI helps your emails stand out and appear more trustworthy, which can lead to higher open rates and better engagement.
