Tuesday, July 29, 2025 • BIMI (CMC/VMC), DMARC, & Gmail’s Manage Subscriptions
Case Brief

Get Your Logo (and Checkmark) Into the Inbox

Gmail's new Manage Subscriptions interface is now rolling out to all users—allowing subscribers to review senders side-by-side and unsubscribe with zero friction. This fundamentally changes the inbox dynamic: brand recognition and trust signals are no longer nice-to-have features, they're survival mechanisms.

The strategic opportunity: Gmail now supports both CMC (Common Mark Certificate: logo display without verification checkmark) and VMC (Verified Mark Certificate: logo plus Gmail's blue verification checkmark). CMC requires only enforced DMARC and organizational validation—no trademark needed. This means you can get your logo live in Gmail inboxes within days, not months.

Implementation Priority (Execute This Week)

Phase 1: Enforce DMARC policy to p=quarantine or p=reject (start with pct=20 for gradual rollout). Phase 2: Obtain CMC through DigiCert or Entrust ($100-300 annually). Phase 3: Deploy BIMI DNS record and validate with Gmail rendering tests. Optional Phase 4: Scope VMC upgrade path if you hold registered trademarks.

Business Impact Data

Early BIMI adopters report 15-25% improvement in open rates and 30% reduction in unsubscribe rates when logos display consistently. In Gmail's subscription hub, branded senders stand out against generic sender avatars, creating immediate visual hierarchy that influences retention decisions.

Primary Diagnosis

DMARC Not Enforced + No BIMI Record

BIMI requires DMARC at p=quarantine or p=reject, plus a third-party mark certificate. Gmail now supports both CMC (easier, logo only) and VMC (logo + blue checkmark). If you lack a registered trademark, ship CMC first, then upgrade.

Secondary Factors

Slow trademark applications, DMARC misalignment (SPF/DKIM), and invalid SVGs delay BIMI deployment. Meanwhile, Gmail's subscription hub makes unsubscribing frictionless—brand trust and visual clarity become competitive advantages.

Treatment Plan (Ship a CMC This Week)
1) Enforce DMARC
  1. Confirm SPF/DKIM align with your visible From: domain.
  2. Publish DMARC with p=quarantine or p=reject (start with pct=20 if needed).
  3. Enable rua= reporting to watch for drift.
2) Prep Your Logo

Export SVG Tiny-PS; ensure clean shapes & no embedded rasters. Keep background transparent.

3) Obtain CMC

Use DigiCert/Entrust to verify org + 12-month logo use; publish default._bimi TXT and test.

4) Verify & Iterate

Validate with Valimail/Red Sift checkers; confirm rendering in Gmail; plan VMC (blue check) if you have a registered mark.

Vitals (Next 30 Days)
BIMI live in Gmail • DMARC enforced • SVG passes Tiny-PS • Optional VMC scoping & trademark path
Observed Outcome
“We shipped CMC in under a week (DMARC already at reject). Logo now shows in Gmail; next quarter we’ll add VMC for the checkmark.”
