BIMI and Brand Logos in the Inbox: Is It Worth It?
BIMI shows your logo next to messages in supporting inboxes. What it needs, what it costs in effort and who should bother.
BIMI (Brand Indicators for Message Identification) lets supporting mailbox providers show your verified logo next to your emails.
What you need
- A DMARC policy at enforcement (quarantine or reject) on the sending domain
- A logo in SVG Tiny PS format, published at a URL
- For some providers, a Verified or Common Mark Certificate that proves the logo belongs to you
- A BIMI DNS record that points to the logo
What you get
- A recognisable logo in the inbox at supporting providers
- A trust signal that can help recognition and engagement
- A reason to finally reach DMARC enforcement
What it does not do
BIMI does not improve deliverability by itself and does not work in every inbox. Support and display rules vary by provider and change over time.
Who should bother
Brands that send high volumes to consumers, financial and e-commerce senders, and anyone whose customers need to tell real mail from phishing.
First things first
Reaching DMARC enforcement requires clean authentication and healthy lists. Fix the foundation before the logo: authenticate your domain and verify your list with the bulk verifier.
What it takes, step by step
- DMARC at enforcement. Your policy must be `quarantine` or `reject`, and applied to all mail. This is the real work and the biggest benefit of BIMI, because it also protects your domain from spoofing.
- A logo in SVG Tiny PS format, square, with a plain background. Many designers need a conversion step.
- A certificate for display in Gmail. A Verified Mark Certificate (VMC) requires a registered trademark; a Common Mark Certificate (CMC) is available for logos used for a period of time without trademark registration. Both cost money each year.
- A BIMI DNS record pointing to the logo and certificate.
Support differs by mailbox provider and changes over time, so check each provider's current documentation before you invest.
Is it worth it
For a brand that sends a lot of consumer mail, a logo next to the sender name can help recognition and trust. It is not a deliverability fix: mail from a poorly authenticated domain does not get better placement because of a logo.
A sensible order
- First: SPF, DKIM, DMARC at enforcement.
- Second: a clean list and low complaint rates.
- Third: BIMI, if your volume and brand justify the certificate cost.
Do the second step right away. A verification of your list is quick, and it lowers bounces whatever you decide about BIMI.
