A BIMI Logo Doesn't Stop Phishing — What BIMI's Security Model Actually Protects Against
Why BIMI Rejects Your SVG Logo — SVG Tiny 1.2 Requirements Explained
BIMI doesn't accept standard SVG files — it requires SVG Tiny 1.2, a restricted profile that prohibits CSS style blocks, external references, filters, and often gradients and text elements. Most SVG files exported from Figma, Illustrator, or Sketch will fail BIMI validation. Here's the exact SVG structure required, why the circular crop means corner-content gets clipped, and the validator errors you're most likely to encounter.
BIMI Display Adoption: Why Your Perfectly-Configured Logo Might Still Not Show Up
A perfectly-configured BIMI setup — valid SPF/DKIM/DMARC, correctly-formatted SVG, even a VMC certificate — can still show no logo in most inboxes, because each mailbox provider independently decides whether and when to display BIMI logos. Here's the provider-by-provider adoption patchwork, why SVG Tiny PS (BIMI's restricted SVG profile) commonly rejects design-tool exports, and why "specification-compliant" and "logo actually displays" are genuinely different claims.
BIMI Certificates Explained: VMC, CMC, and the Trademark Verification Chain
A BIMI logo in an inbox is the endpoint of a verification chain that can include a Verified Mark Certificate — a specific X.509 certificate type tied to trademark registration, issued by a small number of specialised Certificate Authorities. Here's what's actually in a VMC, the CMC alternative, BIMI's restricted SVG logo format, and how it all depends on DMARC enforcement underneath.

SPF, DKIM, and DMARC prove you're legitimate — but engagement rates, complaint rates, list hygiene, and domain age determine whether you land in inbox or spam. Here's the deliverability signals major providers actually use, IP warming schedules, and the 2024 Google/Yahoo requirements in practice.
BIMI Setup Guide: How Email Logo Authentication Fits Into the Full Stack
BIMI is the capstone of email authentication — but it requires SPF, DKIM, and DMARC at p=reject to function. Here's the full setup guide, what Verified Mark Certificates are, which inboxes support it, and the most common misconfigurations.
