Email threats aren’t slowing down, and neither should your authentication strategy. In our recent joint webinar with Marigold, “From DMARC to BIMI: Navigating the New Email Authorization Landscape,” we broke down what today’s evolving standards mean for both security and marketing teams—and how to take action now with our free Red Sift Investigate tool.
If you missed the live session or want the highlights, here’s your quick-fire recap.
Email authentication is rapidly changing
The session kicked off with Red Sift’s Brian Westnedge alongside Marigold’s Casey Stopperan and Ken Pfeiffer broke down the new bulk sender rules from Gmail and Yahoo (and now Microsoft). As of early 2024, both providers are enforcing stricter DMARC requirements for bulk senders—raising the bar for deliverability and domain protection, with Microsoft joining the party in 2025.
In fact, since the announcement in November 2023, domains with DMARC reporting enabled have increased from 6 million to 10 million. If you haven’t yet caught up, these updates are no longer optional. Brands must prove they’re legitimate senders, or risk getting filtered out completely for bulk senders.
DMARC: Your best line of defense
Domain-based Message Authentication, Reporting & Conformance (DMARC) isn’t new—but now it’s non-negotiable. Casey and Ken explained how DMARC helps prevent spoofing and phishing by letting domain owners tell inbox providers how to handle unauthorized email.
But as Brian emphasized, simply having a DMARC record isn’t enough. You need full alignment, proper enforcement, and real-time visibility across every platform and tool sending email on your behalf. Red Sift’s integrated monitoring, Red Sift OnDMARC, helps businesses uncover hidden senders and move from monitoring to enforcement with confidence.
BIMI: Boost security and your brand
Once DMARC is enforced, Brand Indicators for Message Identification (BIMI) is enabled. BIMI lets you display your verified logo next to emails in the inbox—making your brand instantly recognizable and more trustworthy.
There’s a catch: BIMI requires a strict DMARC policy (p=quarantine or p=reject) and either a Common Mark Certificate (CMC) or a Verified Mark Certificate (VMC). Once DMARC is enforced, BIMI is enabled ready to boost your brand, letting your verified logo appear next to your emails in the inbox—creating instant recognition and trust.
Ken further highlighted how BIMI aligns perfectly with Marigold’s focus on deliverability and brand engagement. Meanwhile, Brian showed how Red Sift simplifies the process of getting BIMI-ready by managing everything from VMCs and CMCs to logo validation.
The bottom line? BIMI transforms authentication from a compliance task into a brand-building tool, excellent for security and marketing teams alike.
