Can Attackers Spoof Your Domain?
Most domains can be spoofed by anyone with a Gmail account. This 30-second test shows whether your SPF, DKIM, and DMARC are actually configured to block phishing emails sent from your name — or just suggesting receivers be polite about it.

Why Email Spoofing Is Still the #1 Phishing Vector in 2026
Email was designed in the 1980s with zero authentication. By default, anyone, anywhere, can send a message that says "From: ceo@yourcompany.com" — and unless you've configured SPF, DKIM, and DMARC correctly, most email servers in the world will deliver it.
This is how Business Email Compromise (BEC) wire fraud works. This is how vendor invoice scams work. This is how the "Hi, I'm the CEO, I'm in a meeting, can you buy gift cards real quick" scam works. The attacker doesn't need to hack anything — they just need a domain that hasn't enforced DMARC.
The fix is 3 DNS records, takes 30 minutes, costs nothing, and dramatically reduces successful phishing against your team and your customers. The hard part is rolling DMARC to p=reject without breaking legitimate email — and that's where most Omaha businesses get stuck. The scan shows you exactly where you are on that journey.
FAQ
Common questions from Omaha business owners
Check whether your DMARC record has an rua= reporting address. If it does (and someone is reading those reports), you'll see daily aggregate XML reports showing every server that tried to send mail as you, including spoofers. If you don't have rua= configured, you've almost certainly been spoofed and just don't know about it. The scan flags this.
