Email spoofing is becoming more common in 2026 across all industries. The good news is that most businesses can stop it with a few simple fixes.
If someone is sending fake emails that look like they came from your domain, it usually does not mean your email was hacked. Instead, it means your domain is missing important security settings.
At LI Tech Advisors, we help businesses fix this quickly and properly so spoofed emails get blocked before they reach your customers.
Email spoofing happens when someone sends an email that looks like it came from you—but didn’t.
For example:
It feels serious, and most people assume they were hacked. In most cases, they were not.
Instead, someone simply used your domain name to pretend they were you.

Without security settings, mail servers may accept messages even if they are fake.
That’s where three important tools come in:
Without DMARC, fake emails can still slip through.
Spoofing does NOT require access to your email account.
Attackers do not need your password. They do not need to hack anything.
They only need your domain name—which is public.
If your domain is not protected, they can impersonate your business easily.
Email providers like Google, Microsoft, and Yahoo are now enforcing stricter rules.
If your domain is not set up correctly:
Security and deliverability now go hand in hand.
Protecting your domain is simple and does not change how you send email.
List all approved systems that send email for your business (Microsoft 365, Google Workspace, CRMs, marketing tools, etc.).
This adds a secure digital signature to every email you send.
This tells email providers what to do with fake emails—start with monitoring, then move to blocking them completely.
Many businesses are surprised to learn how many tools send email on their behalf.
Examples include:
If these are not accounted for, you could accidentally block your own emails. That’s why setup should be done carefully.
Once DMARC is properly enforced:
