Are you attending #M3AAWG44 and wondering about the intersection of #DMARC and Top-Level Domains (TLDs)? Curious how a DMARC policy for all of .bank or .uk would work? Attend a working session on Thursday at 9:30AM in Salon D, 2nd floor, to find out and share your own thoughts!

Did you see that GlobalCyberAlliance released a report estimating BEC costs avoided by deploying strict #DMARC policies? globalcyberalliance.org/are-we-making-…

Published #DMARC policies increased 2.5 times in 2018, from roughly 240k to 630k. More at dmarc.org/2019/02/dmarc-… Thanks to Farsight Security for providing the raw data. #EmailAuthentication #M3AAWG

The #ARC protocol published today as RFC 8617! Thanks and congrats to everybody who contributed/supported it along the way! More at dmarc.org/2019/07/arc-pr… #DMARC #M3AAWG #IETF

10/24: Microsoft “enables” #ARC in Office 365, per Microsoft 365 Timeline. Initial use is only “within Office 365,” but working there should get external sealers added. Time to adopt, or at least add to your roadmap... arc-spec.org/?p=173

The ARC Protocol has a new logo to celebrate being published as RFC8617! arc-spec.org/?p=185 #ARC #DMARC

On behalf of the original DMARC project team, #ThankYouJerry - your support for us at #M3AAWG meetings really made a difference and helped us keep moving forward.

Number of observed, valid #DMARC policies grew 300% over 2019, to nearly 1.9MM. See dmarc.org/2020/02/dmarc-… Thanks to Farsight Security for raw DNS data.

Rate of growth of #DMARC records slowed in 2020, but still added 810k records to end at 2.7MM for the year, w/ high monthly growth. dmarc.org/2021/02/dmarc-…

Active #DMARC policies observed in DNS increased by 28% in the first half of 2021, almost double the percentage added as in the same period of 2020. Write-up available here: dmarc.org/2021/10/dmarc-… #email #emailauthentication (Thanks to Farsight Security for raw data!)

#BIMI relies on #DMARC, so we get asked about it. There's some data on new BIMI records over seven months in the middle of 2021, and a little background info, posted here: dmarc.org/2022/01/thousa…

Ten Years of DMARC! Original announcement was on Jan 30, 2012. Thanks to everybody who has embraced DMARC and advanced email authentication. A few more words at dmarc.org/2022/01/dmarc-…. #dmarc #emailauthentication

By the end of 2021 there were nearly 5MM valid DMARC policies observed on the Internet. We've reorganized our site a bit, DMARC stats are now here: dmarc.org/stats/dmarc/

Sharing some stats about observed #DKIM usage here: dmarc.org/stats/dkim/ Number of unique keys tripled in CY2021, not sure yet why. More 2k RSA keys than 1k keys for first time. Only about 2,100 ed25519 keys.

Contributed stats to the keynote/panel on email authentication at M3AAWG's hybrid 54th general meeting on Tuesday. Glad to participate in person again! dmarc.org/stats/ #DMARC #DKIM #BIMI

#DMARC policies increased 84% over CY2021, to nearly 5MM observed & validated. Small writeup and graph here you can cite or share as needed: dmarc.org/2022/03/dmarc-… #emailauthentication

Our #DMARC stats hadn't been updated in a few years, but we've finally posted an update through CY2025. More info here: dmarc.org/2026/02/update…
