Bolster Your Business Email Security

🛡️ Bolster Your Business Email Security

Your business email is the digital front door to your brand — and scammers are knocking every day. Phishing, spoofing, and business email compromise (BEC) attacks are on the rise, targeting Iowa businesses of all sizes. One fake email can cost a company thousands, damage its reputation, or erode customer trust.

Email security isn’t just an IT issue — it’s a business continuity issue. Protecting your email systems helps safeguard your customers, your financials, and your brand reputation.

The Real-World Risk

Email remains the #1 attack vector for cybercriminals. According to the FBI’s 2024 Internet Crime Report, U.S. businesses lost over $2.9 billion last year to business email compromise scams alone. And per the Verizon 2024 Data Breach Investigations Report, 74% of breaches involved the human element — errors, social engineering, or credential theft.

These aren’t just big-city problems. We’ve seen Iowa companies hit with fake invoices, spoofed emails “from the CEO,” and even fraudulent wire transfer requests that looked completely legitimate.

And it’s not just about keeping hackers out — poor email security can also hurt your communication. If your domain isn’t properly authenticated, legitimate messages from your company can end up in your clients’ spam folders, causing missed invoices, delayed approvals, or lost sales opportunities.

Common pain points business owners face include:

Customers receiving fake emails that appear to come from your company

Legitimate messages being flagged as spam or never reaching clients

Employees clicking phishing links disguised as Microsoft 365 or QuickBooks alerts

Losing customer trust after an impersonation scam

Difficulty understanding or managing SPF, DKIM, and DMARC records

The Fix: SPF, DKIM, and DMARC

These three authentication tools form the foundation of modern email protection:

SPF (Sender Policy Framework) – Defines which servers are authorized to send email from your domain.

DKIM (DomainKeys Identified Mail) – Digitally signs outgoing messages so recipients can verify they’re truly from you.

DMARC (Domain-based Message Authentication, Reporting, and Conformance) – Ties SPF and DKIM together to block or quarantine fake messages before they ever reach a customer’s inbox.

When properly configured, these protections drastically reduce phishing and spoofing attempts — and help ensure your legitimate emails land in inboxes, not spam folders.
