Why it matters
Why verified email identity matters
The problem: spoofed brand identity
Attackers impersonate trusted brands using spoofed domains and fake sender identities. Without strong email authentication and visible trust indicators, customers struggle to tell legitimate emails from fraudulent ones.
The cost: lost trust and engagement
When customers receive spoofed messages in your name, brand trust takes the first hit, and inbox deliverability follows. Even legitimate emails become suspect, making campaign performance harder to sustain with every send.
The solution: verified email trust
Authenticated trust signals (a verified sender logo, an authenticated domain, and signed email identity) work together to strengthen email trust. A VMC establishes that trusted inbox identity through BIMI.

Benchmarks for brands displaying their logo and verified checkmark in the inbox, the same lift you can expect once your DMARC, BIMI, and VMC are live. (Red Sift & Entrust 2021, DigiCert/Vitreous World 2025, Tallyfy)
“Brands without their logo in the inbox lose up to 39% of sales share to competitors who have it.”
“49% of consumers say a verified logo influences which brand they choose.”
Recognition
Earn trust at first glance.
A verified logo next to your name is instant proof that an email is really from you. It signals legitimacy before a single word is read, and it's exactly the kind of visual cue phishing and spoofed senders can't fake, because it's tied to your registered trademark, not just a display name.

Deliverability
Land where it matters.
Getting to a VMC requires DMARC at enforcement, which is also one of the strongest signals inboxes use to decide what lands in the primary tab versus spam. So the same work that unlocks your logo also improves deliverability, and once you're verified, your brand mail visibly stands out from everyone still sending unauthenticated.
