What we check and why

What BIMI is

Brand Indicators for Message Identification (BIMI) is a standard that lets you publish a logo in DNS so that participating mailbox providers can display it next to authenticated messages from your domain. Gmail, Apple Mail, Yahoo and several other providers support it, each with its own conditions. It is a reward for strong email authentication, not a replacement for it.

The requirements we check

  • DMARC at enforcement: p=quarantine or p=reject with full coverage — BIMI is ignored with p=none.
  • A BIMI TXT record at default._bimi.yourdomain with v=BIMI1 and an l= logo URL.
  • The logo itself: fetched over HTTPS and in the SVG Tiny Portable/Secure (SVG Tiny PS) profile that BIMI requires.
  • An a= link to a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC), which Gmail and Apple Mail require to show the logo.
  • SPF and DKIM, which must pass and align for messages to qualify.

Is BIMI worth it for a firm?

The main benefit of the journey is the DMARC enforcement you need to get there, which protects your clients from forged emails. The logo itself is a visible trust signal in crowded inboxes, but only in supporting mail apps and only after the provider decides to display it.

Certificates cost money. A VMC typically requires a registered trademark for the logo; a CMC requires evidence that you have used the logo for at least a year, without a trademark. Both are issued by a small number of certificate authorities after identity checks. Weigh that cost against how much of your client correspondence reaches Gmail and Apple Mail users.

If you decide to go ahead, start with DMARC: it usually takes a few weeks of reports to reach reject safely. Prepare the SVG Tiny PS logo in parallel, then publish the BIMI record and add the certificate once it is issued.

What we cannot check

We cannot verify that a certificate has been accepted by a particular mailbox provider, and we cannot see whether your messages pass DMARC in practice, since that depends on the servers that send them. The report covers the published records and files; confirm the result by sending a test message to a Gmail or Apple Mail account once everything is in place.

Frequently asked questions

Can I use BIMI without a certificate?

Some providers, such as Yahoo, may show a logo without one for senders with good reputation. Gmail and Apple Mail require a VMC or CMC.

Why is my logo not showing?

Check DMARC enforcement, the SVG Tiny PS format, the certificate, and that messages pass DMARC. Even then, providers apply their own reputation criteria.

How do I make an SVG Tiny PS logo?

Start from a square vector logo, remove scripts and external references, and set version="1.2" and baseProfile="tiny-ps" with a title element. Several free converters and guides from the BIMI Group help.

Does BIMI improve deliverability?

Not directly. The underlying authentication and DMARC enforcement help; the logo may improve recognition and open rates.
