If you send unencrypted data by email, you may wish to take precautions to prevent data loss. That’s where DMARC’s email data loss prevention is useful. Email fraud volume decreased from 282.93 billion per day in July 2021 to 88.88 billion per day globally.
The DMARC enforcement of rules and standards supports a thorough deployment of email data loss prevention. It’s crucial to reduce the chance that private data about a company could get into the wrong hands.

Email Data Loss: What Is It?
When you discuss email fraud, you mean a hacker has got access to your emails. It could happen after a password reset or because of a cybersecurity phishing scam. Your emails are vulnerable in either case. Email data loss is a frequent issue for both businesses and consumers. Recovery from email data loss can be challenging.
Cybersecurity attacks are caused by human error, such as when a person unintentionally clicks the wrong button or types the wrong URL. Viruses, malware, and criminal interceptions are a few additional causes of email flow corruption in an organization.
What are the Reasons for Email Data Loss?
Email privacy data loss can happen for the reasons listed below:
- Compromised email account
- The email address is fake
- Because of “man in the middle” assaults
- Due to the transit email interception
Can DMARC Be Used To Reduce Email Data Loss?
With DMARC, the prevention of email data loss with DMARC is possible by allowing email systems to recognize communications that are invalid.
Email is used to send the organization’s email domain and other personally identifiable information (PII). Email data loss prevention with DMARC prevents these from being distributed to undesired recipients.
Implement email authentication methods and approaches, such as adhering to your email security to get prevention:
- SPF and DKIM protocols recognize messages as coming from people who have permission to send them.
- Emails deliver to the intended recipients.
- During online email transactions, neither data leaks nor communication interceptions happen.
Data loss prevention is a process that goes above and beyond warnings to secure sensitive data by applying compliance rules. You must go into detail about the advantages of email security of the DMARC policy and how it fits into this proactive DLP solution.
1. DMARC Sends Reports on Domain Visibility
As a single source of information for all domains sending emails, DMARC services as a registry of the domain ownership. Using DMARC for fraud prevention by your recipients enables them to send aggregate reports. These are rich in data about your sending sources and authentication status. And aid in the detection of spam, phishing, cybersecurity, and other criminal actions leading to email data loss.
The reports include basic details like the SMTP addresses of the sender and recipient and the subject line. They also include more sophisticated insights like the allowed and unauthorized IP addresses. And the instances where protocols (DMARC, SPF, and DKIM) were broken.
Such transparency enables you to improve your email channel in an educated manner, which can aid in preventing data loss.
2. Prevents Delivery of Spam and Invalid Outgoing Messages
If email data is lost, sensitive firm information could end up in the wrong hands leading to harmed brand protection. It damages your company’s brand since customers lose faith in you if they learn you have misplaced their private data.
DMARC aids in preventing the delivery of unwanted communications from spammers who use your domain name. For instance, DKIM (Domain Keys Identified Mail) signs messages from a domain and authenticates them using public-key cryptography.
This stops attackers using the man-in-the-middle technique from intercepting messages before getting to their target and affects brand protection.
3. Prevents Messages from Phony Email Addresses from Arriving
When a hacker sends a message that looks to be from your trusted domain, this is known as email spoofing. These bogus emails typically include ransomware attachments and phishing URLs. By tricking your company’s employees or clients into opening the attachment, malware jeopardizes their security.
To stop incoming and outgoing spam messages from forged email addresses, the DMARC record checker employs SPF. SPF accomplishes this by comparing a sender’s IP address to the IP address specified in the domain owner’s SPF DNS record.
4. Get Instant Alerts for Email Infrastructure Changes
Having an alarm system that isn’t sensitive enough is only slightly worse than having none for email data loss. If you make changes to your email infrastructure, you, as the domain owner, need to recognize them right away. So, you can respond to them appropriately if you did not do them.
This is where DMARC comes into play. Because it looks for indications of misuse and other questionable behavior, it provides businesses with a tool to monitor their email infrastructure with high sensitivity. It immediately alerts you if something seems odd so you may take action before anybody else does.
This implies that you will get a notification if a rule changes. It is useful for preventing email data loss of scale since it immediately alerts you if the email system compromises.
5. Identifies the Sender of Spam
One of the most crucial aspects of DMARC is it lessens the possibility of attackers abusing your email to utilize the domain name. For each email sent from your domain, it adds DNS record, enabling you to see who is sending spam and why.
Wrapping It Up
Email is an effective commercial communication tool, but it can also work as a destructive weapon. Fortunately, you can make sure unauthorized people do not send or receive that emails by monitoring your authentication results.
And GoDMARC’s DMARC services actually carry out that task! Each customer or partner receives frequent sync-up calls from their DMARC Support Team. You can discuss how to use the DMARC Dashboard, share knowledge, and fill up any gaps in email authentication. Lookout for several options for choosing DMARC pricing plans to avail of their services.
Q1 What is the most effective way to stop data loss?
- Frequently plan “fire drills” to restore data from backups.
- Keep computers in places that are secure, dry, and free of dust.
- Maintain regular data backups.
- Prevent static electricity from damaging components or erasing data on equipment.
Q2 How do DLP tools work?
The most widely used security techniques for ensuring data security and preventing data breaches are by far data loss prevention solutions. In order to identify potential security policy violations and, if required, put a stop to them, DLP solutions continuously monitor and analyze data.
Q3 What are the three phases in preventing data loss?
The DLP typically accomplishes this in three steps
- Determining the location and timing of the data loss
- Determining what data was lost
- Resecuring the remaining data.
