How to Secure Email & Improve Deliverability (DMARC Tutorial)

How DMARC Stops Spoofing and Phishing

Email spoofing and phishing attacks pose a serious threat to businesses, with over 3.1 billion spoofing emails sent every single day. These attacks erode trust, harm brand reputation, and disrupt business relationships. DMARC helps tackle this problem by using an advanced authentication system that blocks fraudulent emails before they even reach their targets.

The numbers paint a grim picture. More than 90% of cyberattacks begin with an email, and according to the FBI's 2023 Internet Crime Report, nearly 34% of respondents (298,878) reported spoofing-related complaints. For B2B companies, where trust is non-negotiable, these statistics highlight a pressing risk. Let’s dive into how SPF and DKIM work alongside DMARC to protect email communications.

How SPF and DKIM Work with DMARC

SPF, DKIM, and DMARC work together to create a layered system for verifying email authenticity, with each playing a distinct role.

SPF (Sender Policy Framework) acts like a publicly accessible employee directory. When an email claims to come from your domain, SPF checks whether the email was sent from an IP address you’ve authorized. Domain owners publish SPF records in their DNS to specify which mail servers are allowed to send emails on their behalf. If an email originates from an unauthorized server, SPF flags it as suspicious.
DKIM (DomainKeys Identified Mail) works like a signature on a check. It uses cryptographic methods to attach a digital signature to emails, ensuring the message hasn’t been altered during transit. The receiving server verifies this signature using your public key stored in DNS, confirming the email’s integrity.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) takes it a step further by requiring the "From" address to align with the domain validated by SPF or DKIM. This dual-layer verification makes it much harder for attackers to spoof your domain.

As of September 2024, nearly 6.8 million domains had implemented email sender authentication. Yet, 75% of companies are still in the process of rolling out DMARC, highlighting the need for broader adoption to enhance email security. With SPF, DKIM, and DMARC working together, businesses can enforce policies that block phishing and spoofing attempts.

Preventing Phishing and Spoofing Attacks

DMARC’s true power lies in its ability to enforce policies that actively prevent malicious emails from reaching their targets. It provides three policy options:

Monitor (p=none): Gathers data on email activity without affecting delivery.
Quarantine (p=quarantine): Sends failed emails to spam folders.
Reject (p=reject): Blocks failed emails entirely.

By applying these policies consistently, businesses can strengthen trust in their email communications, particularly in B2B settings.

The effectiveness of DMARC is backed by real-world examples. In 2018, a Maropost client implemented DMARC and saw phishing alerts disappear entirely while achieving a 100% success rate for email delivery. However, attackers are constantly adapting. A study by Darktrace revealed that 65% of phishing emails successfully passed DMARC verification, highlighting the importance of proper implementation and ongoing monitoring.

DMARC also provides reporting tools that reveal which emails pass or fail authentication. These reports help domain owners quickly identify unauthorized use of their domains and address potential threats - an essential step for securing B2B communications.

For businesses focused on outbound lead generation, DMARC offers more than just security. By preventing bad actors from misusing your domain, DMARC protects your sender reputation and ensures legitimate emails land in prospects’ inboxes instead of getting flagged as spam. At Artemis Leads, we emphasize strong email authentication practices, including DMARC, to ensure every message fosters trust with decision-makers.

These measures are crucial for safeguarding B2B communications and maintaining the integrity of your sender reputation.

How DMARC Improves Deliverability and Builds Trust

DMARC plays a crucial role in verifying emails, offering reassurance to Internet Service Providers (ISPs) about their legitimacy. When emails successfully pass DMARC checks, they are far more likely to land in recipients' primary inboxes rather than being flagged as spam.

How DMARC Improves Deliverability

DMARC has a direct and measurable impact on email deliverability. When an email clears DMARC verification, it essentially carries a badge of authenticity, signaling to receiving servers that the message originates from an authorized source. This process gives ISPs the confidence to treat your emails as genuine, significantly reducing the chances of them being marked as spam or blocked altogether.

For many brands, implementing DMARC can lead to a noticeable improvement in deliverability - up to a 10% increase after reaching full DMARC enforcement. One striking example comes from Google: by enforcing strict domain authentication, they reduced unauthenticated emails by 65%, cutting down on 265 billion unauthorized messages in 2024 alone. By filtering out fraudulent messages, DMARC helps legitimate emails stand out, ensuring they reach their intended audience.

The key to maximizing deliverability lies in proper DMARC implementation. Starting with a monitoring policy allows you to analyze your email traffic and address issues before moving to stricter enforcement. Once all legitimate email sources are authenticated, applying quarantine or reject policies ensures only verified messages make it to recipients' inboxes. This approach not only improves deliverability but also strengthens the foundation for successful outbound communication efforts.

Impact on Outbound Lead Generation

Strong deliverability paves the way for trust, a critical element in B2B outbound lead generation. When your emails consistently land in decision-makers' inboxes, they are more likely to trust your outreach efforts. This trust fosters meaningful engagement, opening doors to stronger relationships and better opportunities.

"DMARC protects brands by serving as a gatekeeper - it prevents bad actors from spoofing your domain and sending out emails that appear to come from your brand. Publishing your DMARC record can result in a boost to your reputation." – ITS Services

The importance of trust becomes even clearer when you consider that 90% of network attacks are carried out using email infrastructure. In a world where decision-makers are increasingly wary of email communication, DMARC authentication acts as a signal of legitimacy. This reassurance not only helps your emails stand out but also amplifies the effectiveness of your lead generation efforts.

At Artemis Leads, we've seen firsthand how proper email authentication elevates outbound campaigns. When prospects receive emails that pass DMARC checks, they recognize the professionalism and security behind the communication. This credibility increases engagement rates and builds confidence in your brand. Additionally, DMARC offers valuable visibility into your email ecosystem, identifying every source sending messages from your domain. This ensures that every step of your lead generation process adheres to consistent authentication standards.

With DMARC in place, your emails don’t just reach more prospects - they arrive with the reliability and credibility that busy executives value when deciding whether to engage with new business opportunities.

DMARC Reporting and Policy Optimization

DMARC's reporting features are key to understanding and refining your email authentication strategy. They help you distinguish legitimate emails from potential threats, which is critical considering that over 90% of cyberattacks start with email fraud. Gaining visibility into your email ecosystem is essential to safeguarding your business reputation.

The system gathers data from receiving mail servers and translates it into actionable insights. This is especially important for B2B organizations, where email credibility can directly influence vital business relationships. Let’s take a closer look at the two types of reports DMARC provides.

Understanding DMARC Reports

DMARC produces two types of reports, each serving a unique purpose in monitoring your email ecosystem.

Aggregate reports offer a high-level overview of DMARC evaluation results. They include details like the IP addresses sending emails from your domain, authentication pass and fail rates, and the actions taken on emails that fail authentication. These reports are sent regularly and provide a broad view of your email traffic patterns.
Forensic reports are more immediate. They notify you in real time about DMARC failures, much like bounce messages. These reports contain detailed information about emails that failed authentication, enabling you to investigate suspicious activity as it happens.

Aggregate reports are especially useful for understanding your email infrastructure. They highlight which sources successfully authenticate with your domain and which fail DMARC checks, while also showing the volume of email traffic from each sender. For businesses juggling multiple email campaigns or third-party services, this data is crucial for maintaining consistent authentication across all channels.

Using Reports to Improve Policies

Optimizing your DMARC policy starts with analyzing report data and making gradual adjustments. A common approach is to begin with a relaxed policy (p=none) and tighten enforcement as you resolve authentication issues.

To manage this effectively, assign a dedicated team or set up a specific mailbox to handle DMARC reports. This ensures that critical security information doesn’t get lost in general email traffic. Many organizations streamline this process by using external tools or automation platforms - like PowerShell or Power BI - to interpret aggregate report data more efficiently.

When reviewing reports, focus on identifying non-compliant sources and resolving issues with SPF and DKIM configurations. If legitimate emails are failing authentication, determine whether the sender needs to be added to your SPF record or if DKIM settings require adjustment. Properly aligned DKIM signatures and authentication ensure all legitimate senders appear compliant in your reports.

The optimization process involves regularly reviewing reports, addressing issues, and updating your policies accordingly. This might include revising DKIM signatures, updating SPF records, or fine-tuning your DMARC policy settings based on observed patterns.

As your authentication results improve and legitimate sources consistently pass DMARC checks, you can gradually shift from a monitoring policy (p=none) to a quarantine policy (p=quarantine), and eventually to a reject policy (p=reject). This staged approach minimizes the risk of blocking legitimate emails while strengthening your domain’s defenses.

Forensic reports also play a critical role in identifying new attack patterns. By analyzing these reports, you can proactively adjust your defenses to address emerging threats. This ongoing cycle of review and improvement not only secures your domain but also reinforces the trust recipients have in your email communications. Such trust is essential for maintaining strong B2B relationships and ensuring the success of your outbound email strategies.

Setting Up DMARC for B2B Lead Generation

Setting up DMARC for your B2B emails is a smart move to protect your domain and ensure your legitimate messages make it to the inbox. Here's how you can get started.

Steps for DMARC Setup

Before diving into DMARC, make sure SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are already active on your domain. These protocols are the foundation for DMARC and are essential for effective email authentication.

Next, log in to your DNS manager and create a TXT record with the hostname . Use the following initial DMARC record:

In this record:

The tag tells receiving mail servers how to handle emails that fail authentication. Options include , , or .

Start with a policy. This policy allows you to monitor email activity without affecting delivery. During this phase, review DMARC reports to identify all authorized email sources, such as marketing tools, support platforms, and third-party services. Once you're confident that more than 95% of your emails are authenticating successfully, you can gradually tighten the policy to and eventually to .

With DMARC properly set up, you’ll immediately see its impact on your lead generation efforts.

DMARC's Role in B2B Lead Generation

DMARC isn’t just about security - it plays a critical role in improving the effectiveness of your B2B outreach. Email authentication is especially important when targeting decision-makers, who often deal with hundreds of emails daily and rely on strict filters to separate legitimate messages from spam.

Authenticated emails are proven to perform better. For instance, cold emails that pass authentication see a 37% higher open rate and a 20–30% increase in inbox placement. This means your messages are more likely to land in the primary inbox rather than being flagged as spam, giving your lead generation campaigns a significant boost without requiring extra effort.

Take Artemis Leads as an example. They combine email outreach with LinkedIn messaging, and their proper email authentication ensures decision-makers are more likely to engage. This not only improves campaign performance but also builds long-term trust with email providers, creating a positive feedback loop that benefits all your email marketing initiatives.

Meeting Industry Standards

DMARC compliance isn’t just a best practice - it’s becoming mandatory. Providers like Google and Yahoo now require bulk email senders to use DMARC, reflecting the growing emphasis on email security.

This shift is especially urgent given the current threat landscape. In 2022 alone, more than 500 million phishing attacks were reported globally - double the number from 2021. Business email compromise scams caused $2.9 billion in losses in 2023, with an average loss of $174,000 per incident. These numbers highlight why email providers are tightening authentication requirements.

DMARC adoption is rapidly growing, with 110,000 new domains implementing it each month. To stay ahead, regularly audit all sending domains and update your DNS records for SPF, DKIM, and DMARC as needed. Partnering with email providers that offer built-in support for these protocols ensures your system remains compliant and effective, all without disrupting your lead generation efforts.
