Even in the present world where there is rush in everything that one does, e-mail is the most popular method of communication. However, it is also the most used and therefore exposed to various cyber threats by criminals aiming to penetrate its system. Cybercrimes such as phishing, email spoofing, and other services exist, damaging the reputation of the brand and customers’ trust.
A method to fight these threats is the use of DMARC, an acronym for domain-based message authentication, reporting, and conformance. However, like any reliable security solution, deploying DMARC alone is insufficient; you must actively monitor it to maintain its effectiveness. It is here that a DMARC checker comes in. In this post, I will explain what DMARC is, why your business needs a DMARC Checker, and how you can effectively use it to secure your business against email threats.
What is DMARC?
DMARC is an email authentication protocol that works with two other protocols: Two main mechanisms at present are SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Mail). Both of them confirm the sender’s authenticity and the contents of an email. DMARC acts like a security guard for your email domain, preventing unauthorized access. It stops malicious actors from impersonating you and your brand, blocking them from sending deceptive emails using your domain.
DMARC primarily serves three purposes:
- Authenticate: The function checks the authenticity of the sender of the mail using SPF and DKIM.
- Report: Included in the feedback is all the emails that failed the authentication check.
- Instruct: Determines the action to be taken against any email that does not pass through the DMARC authentication process you set.
Why You Need a DMARC Checker
A DMARC Checker helps you monitor and audit your domain’s DMARC configuration effectively. Just because a business has DMARC in place means that threats do not switch, and new unidentified senders can emerge. A DMARC Checker makes sure that your domain is secure and will notify you of any problems.
Here are some of the top reasons why you need a DMARC Checker:
- Enhanced Domain Security: Prevent threats that can affect your business by implementing mechanisms that counter cases of phishing and spoofing.
- Improved Email Deliverability: Make it possible for your business’s genuine email correspondences to get delivered in recipients’ inboxes and not in the spam folder.
- Comprehensive Reporting: Get reports that indicate which senders are conforming and which you should follow up on to ensure they do the right thing.
Understanding DMARC Policies
There are three main DMARC policies:
| DMARC Policy | Definition | Action Taken | Best for |
| None (p=none) | This policy monitors and reports on email activities but does not enforce any actions. | Emails get delivered regardless of authentication results. | Learning about your domain’s email activities without making immediate changes. |
| Quarantine (p=quarantine) | Suspicious emails that fail DMARC checks get flagged and move to the recipient’s spam or junk folder. | Emails get marked as potentially harmful. | Gradual implementation of DMARC policies to reduce risks. |
| Reject (p=reject) | This is the strictest policy. It blocks all emails that fail DMARC checks from reaching the recipient. | Emails are blocked entirely. | Domains are facing frequent spoofing attacks and have established trust with compliant senders. |
These policies give you the flexibility to choose a suitable level of security based on your business needs.
Features to Look for in a DMARC Checker
Not all DMARC Checkers offer the same features. To get the best results, consider the following key features:
- Detailed Reporting: A good DMARC Checker should offer you a summary of all the email sending activities as listed below. This also involves identification of unauthorized senders.
- SPF and DKIM Validation: The tool must ensure that your current SPF and DKIM records are properly configured to work seamlessly with your DMARC policy.
- Custom Alerts: To receive an alert any time there are incriminating activities or when there has been a violation of the DMARC policy.
- User-Friendly Dashboard: An easy-to-navigate layout that allows you to quickly view and understand the information presented in the reports.
- Policy Recommendations: Get automatic recommendations for policy changes based on the insights gathered to help you make good decisions.
How to Use a DMARC Checker
- Set Up Your DMARC Record: The first is to create a DMARC record, then implement it in the DNS for your domain. This record will specify your DMARC policy.
- Run the DMARC Checker: Place your domain into the tool and let the tool analyze it to discover possible problems in the DMARC setup.
- Review the Results: Exploring the report that the DMARC Checker provides. It should show the compliance level of your emails and any unauthorized source.
- Fix Issues: If there are such cases, immediately take corrective measures to eliminate any mistakes in the SPF/DKIM records values for the senders.
- Monitor and Optimize: They should also emphasize that DMARC policies need to be periodically adjusted based on reports and insights to continuously improve email security and protection.
