Protect Your Business Email: Why DKIM and DMARC Matter

In today’s digital world, email is one of the most important tools for small businesses. It’s how you communicate with customers, vendors, and partners. But did you know that your business email could be used by cybercriminals to send fake messages pretending to be you?

That’s where DKIM and DMARC come in—and why Excelero IT Solutions includes them in our security services.

✉️ What Are DKIM and DMARC?

Let’s break it down simply:

• DKIM (DomainKeys Identified Mail) is like a digital signature for your emails. It proves that the message really came from your business and hasn’t been tampered with.
• DMARC (Domain-based Message Authentication, Reporting & Conformance) is like giving instructions to email providers:
  “If someone tries to send fake emails pretending to be us, block them or mark them as suspicious.”

Together, these tools help protect your brand, your customers, and your reputation.

🚨 Why This Matters for Small Businesses

Even small businesses are targets for email scams. If someone sends fake emails using your business name, it can:

• Damage your reputation
• Confuse or scam your customers
• Cause your real emails to end up in spam folders

By using DKIM and DMARC, you’re telling email services:
“We take security seriously—and we’re protecting our name.”
