Why Email Spoofing Still Works in 2026
Here's the uncomfortable truth: by default, anyone on the internet can send an email that says "From: yourname@yourcompany.com", and most email servers will deliver it. The only thing stopping them is whether your domain has SPF, DKIM, and DMARC records configured correctly.
Most Omaha small businesses we scan have a partial setup: SPF exists but is too permissive ("~all" instead of "-all"), DKIM is signed but DMARC is missing, or DMARC exists but is set to p=none — which means "please report problems but don't actually block anything." Attackers know this and exploit it.
The fix is usually 3 DNS records, takes 15 minutes, and costs nothing. The hard part is knowing what those records should say for your specific email setup (Microsoft 365, Google Workspace, SendGrid, Mailchimp, etc.). The scan tells you what you have, what's missing, and exactly what to add.
FAQ
Common questions from Omaha business owners
SPF says "these are the servers allowed to send email for my domain." DKIM cryptographically signs each message so receivers can verify it wasn't tampered with. DMARC ties them together and tells receivers what to do when SPF or DKIM fails — quarantine, reject, or just report. You need all three for real protection.
