Open a DMARC report and most sources fall into three piles: your own mail, forgotten tools (CRM, invoices — fix these first), and possible forgers. The middle pile is what breaks when you tighten policy. Guide: 👇

Authenticate before adding email volume. Unauthenticated domains often end up in spam folders, wasting outreach efforts. Ensure SPF, DKIM, and DMARC are set up as a foundation.

Launch day: a handful of people ran my free email health check. Most domains with a DMARC record were on p=none, which only watches. Spoofed mail still gets through. If that's you: read your reports, fix your real senders, then move to p=quarantine. Check yours:

Uncle just got a phishing email from "Statement@ssa.us.gov" purporting to be an invitation for him to review his most recent Social Security Statement.
Of course, real emails of that sort come from "ssa.gov", not "ssa.us.gov".

Version 4 of my DMARC report reader files each daily report as dated evidence, remembers every server that has sent mail as my domain, and flags any it hasn't seen before. It shows a dry run first and never deletes. How do you keep your DMARC reports? #DMARC #EmailSecurity #Python

Like, I have a ton of problems with #dmarc, but the one thing that it is absolutely, positively good for is putting DMARC records on domains that legitimate email never originates from to tell receiving servers, "Yo, don't trust anything that comes from this domain, it's lying."

"SPF pass" can still mean DMARC fail. If your sending service bounces mail through its own domain, SPF passes for THEIR domain, not yours, and DMARC does not count it. Paste a message's headers and we show you which: https://www.capradomains.com/email-health?ref=bsky #email #deliverability #dmarc
