#70: Top 5 Reasons SPF, DKIM, and DMARC Fail

Season #1

Cash in the Cyber Sheets is where small and midsize business owners finally get the straight talk on cybersecurity without the jargon, the scare tactics, or the thousand-page compliance manuals. Each week, we pull back the curtain on the hidden forces that make or break your business online, from email deliverability to data protection, and give you simple, actionable steps you can use right now.

Email is still the front door of every business and attackers know it. Spoofing, phishing, and spam aren’t just annoyances, they’re direct threats to your sales pipeline, your customer relationships, and your reputation. That’s why we spend time breaking down the three most important email authentication protocols you need to understand: SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance).

But here’s the thing: setting them up once isn’t enough. Every week, we see small businesses losing revenue because of common mistakes, missing DNS records, too many SPF lookups, expired DKIM keys, or misaligned domains that silently break authentication. In our episodes, we don’t just explain what SPF, DKIM, and DMARC are, we explain why they fail, how to spot the problems early, and what you can do to fix them before they wreck your deliverability.

We keep it practical, with clear analogies and business-owner-friendly examples: SPF is your guest list, DKIM is your digital wax seal, and DMARC is your rulebook that ties them together. Whether you’re sending invoices, running email campaigns, or just trying to keep phishing out of your client inboxes, these protocols matter and we make them simple.
