DMARC

Protect Your Business From Email Fraud With DMARC

March 18, 2025

Email is the backbone of modern business, but it’s also one of the easiest ways for cybercriminals to attack.

If you’ve ever received a fake email that looks like it came from a trusted company, you know how convincing these scams can be. Worse, what if scammers used your business’s email to trick your customers?

That’s exactly what happens with email spoofing—when hackers send emails pretending to be from your domain to steal information, spread malware, or commit fraud. The result? Lost trust, damaged reputation, and even financial losses.

Fortunately, there’s a solution: DMARC (Domain-based Message Authentication, Reporting, and Conformance).

What is DMARC?

DMARC is a security standard that protects your business from email spoofing and phishing attacks. It ensures that emails sent from your domain are legitimate and blocks fraudulent emails before they reach customers, vendors, or employees.

Think of it like a security checkpoint for your email. Only verified messages get through, while fake ones get stopped.

Why your business needs DMARC

Many business owners believe email fraud is only a problem for large corporations. But in reality, small and mid-sized businesses are prime targets because they often lack strong security measures.

Without DMARC:

Your emails could be marked as spam – Clients and vendors may never see important messages like invoices or proposals.

Scammers can impersonate your company – Fraudsters can send emails pretending to be from your business, putting your reputation at risk.

You could face compliance and legal issues – Industries like finance, healthcare, and retail are tightening cybersecurity requirements, and failing to secure your email could lead to penalties.

With DMARC, you can:

Prevent email fraud and phishing attacks – Keep criminals from impersonating your business.

Ensure your emails get delivered – No more important messages going to spam.

Protect your reputation – Customers and partners will trust that emails from your domain are legitimate.

Stay ahead of security compliance – Meet industry regulations and avoid costly fines.

Why DIY isn’t the best option

Implementing DMARC is not as simple as flipping a switch. If done incorrectly, it could accidentally block legitimate emails from reaching their destination.

It requires careful setup, monitoring, and ongoing adjustments to ensure your emails are secure but still get delivered. This is where Tech Experts comes in.

Google & Yahoo’s New DMARC Policy – Why Businesses Need Email Authentication

May 13, 2024

Have you been hearing more about email authentication lately? There is a reason for that. It’s the prevalence of phishing as a major security threat. Phishing continues as the main cause of data breaches and security incidents. This has been the case for many years.

A major shift in the email landscape is happening. The reason is to combat phishing scams. Email authentication is becoming a requirement for email service providers. It’s crucial to your online presence and communication to pay attention to this shift.

Google and Yahoo are two of the world’s largest email providers. They have implemented a new DMARC policy that took effect in February 2024. This policy essentially makes email authentication essential. It’s targeted at businesses sending emails through Gmail and Yahoo Mail.

But what’s DMARC, and why is it suddenly so important?

The email spoofing problem

Imagine receiving an email seemingly from your bank. It requests urgent action. You click a link, enter your details, and boom – your information is compromised. The common name for this is email spoofing.

It’s where scammers disguise their email addresses. They try to appear as legitimate individuals or organizations. Scammers spoof a business’s email address. Then they email customers and vendors pretending to be that business.

These deceptive tactics can have devastating consequences on companies. These include:

  • Financial losses
  • Reputational damage
  • Data breaches
  • Loss of future business

Unfortunately, email spoofing is a growing problem. It makes email authentication a critical defense measure.

What is email authentication?

Email authentication is a way of verifying that your email is legitimate. This includes verifying the server sending the email. It also includes reporting back unauthorized uses of a company domain.

Email authentication uses three key protocols, and each has a specific job:

  • SPF (Sender Policy Framework): Records the IP addresses authorized to send email for a domain.
  • DKIM (DomainKeys Identified Mail): Allows domain owners to digitally “sign” emails, verifying legitimacy.
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance): Gives instructions to a receiving email server including, what to do with the results of an SPF and DKIM check. It also alerts domain owners that their domain is being spoofed.

SPF and DKIM are protective steps. DMARC provides information critical to security enforcement. It helps keep scammers from using your domain name in spoofing attempts.

Why Google & Yahoo’s new DMARC policy matters

Both Google and Yahoo have offered some level of spam filtering but didn’t strictly enforce DMARC policies.

Starting in February 2024, the new rule took place. Businesses sending over 5,000 emails daily must have DMARC implemented.

Both companies also have policies for those sending fewer emails. These relate to SPF and DKIM authentication.

Look for email authentication requirements to continue and be more strictly enforced. You need to pay attention to ensure the smooth delivery of your business email.

The benefits of implementing DMARC include:

  • Protects your brand reputation
  • Improves email deliverability
  • Provides valuable insights
