Before understanding the concept of DMARC record, it is important have a basic knowledge of “what is DMARC”.
DMARC stands for Domain-Based Message Authentication, Reporting and Conformance. In simple words, DMARC is a technical protocol which protects email senders and recipients against cyber attacks including spoofing, phishing, spamming etc. In order to ensure the proper implementation of DMARC, one requires to set DMARC record.
What is DMARC Record?
A DMARC record is the core of DMARC implementation in which a set of rules are defined. This security protocol prevents corrupt entities from sending emails by misusing user’s domain. DMARC record consists of DMARC policies that are set as per the discretion of the domain owner.
With the help of DMARC policy, domain of the sender can decide whether it wants to be protected by either SPF or DKIM or both. This further informs the receiver to take the required action if neither of those authentication methods is passed. The policy either rejects the message or quarantines it, depending upon the implementation.
Furthermore, this policy also specifies whether the email receiver can report back to the domain of the sender, regarding messages that have passed and/or have failed. DMARC policies are reported in public DNS (Domain Name System) as TXT (text) records. To check your DMARC record, click here.
Role of DKIM and SPF in DMARC Record
DMARC is an email authentication protocol that provides instructions to the receiving email servers on how to enforce and act upon the incoming mails. Although DMARC is built on two key verification standards which include SPF and DKIM.
SPF (Sender Policy Framework): SPF is a DNS txt entry which ensures a list of servers that should be considered to send email to a specific domain. This list of domain approved sending hosts as well as IP addresses are, then published in DNS records. Get more details for your SPF TXT record generator here.
DKIM (Domain Key Identified Mail): In order to prevent the delivery of harmful email or to detect any forgery, this protocol comes in handy. It verifies whether the email was sent from an authorized mail server or not. For better DKIM record generator information, click here.
What is a DMARC Policy?
DMARC Policy informs email receivers and other mailbox service providers about the required action that should be taken when an email authentication fails. These policies prevent email domains from email spoofing but the user must have adopted DMARC. There are three main DMARC policies: none, quarantine and reject.
The DMARC policies are of three types:
Under this policy, the email receiver does not take any action if emails fail DMARC authentication. Emails are simply sent into the receiver’s inbox while the domain owner gets the information of spoofed emails with the DMARC report data.
Here, emails receivers are instructed to inspect emails that have failed the DMARC authorization. The email is delivered into either junk or spam folder. Although, the policy entirely depends upon how the user sets it.
This policy indicates that all the emails that have failed any of the parameters, are rejected and restricted from being sent to the receiver. In any case, if a user wishes to change any policy, it might take days to regenerate new policies.

How DMARC Record Works?
DMARC records are published with subdomain label _dmarc in DNS, for example, _dmarc.xyz.com. This is compared to SPF at xyz.com and DKIM at selector._dmoinkey.xyz.com.
TXT resource records comprises of name=value tags, which are separated by semicolons, just as SPF and DKIM.
“v=DMARC1; p=none; sp=quarantine; pct=100; rua=mailto:firstname.lastname@example.org;”
The above mentioned variables have the following meaning:
- v stands for the version
- p stands for the policy
- sp is the sub domain policy
- pct is for the percent of “bad” emails up on which the policy is applied
- rua is the URI that is required to send aggregate reports
Although it takes a good long time to generate DMARC record since various coding parameters are involved in this process; record generation and analyzing tools like KDMARC help in balancing the all uneven factors.
How KDMARC Benefits the DMARC Record?
Implementing only DMARC is not enough when it comes to complete email security. There are various other factors that are required to keep the email engagement going. DMARC only provides limited email authentication feature, whereas, it lags behind when it comes to generating DMARC records on time.
With such issues in hand, the inflow of emails gradually decreases in rate, leading to less email deliverability and engagement. To overcome above said factors, tools like KDMARC come in handy.
Kratikal, a cyber-security solution providing firm, provides an unparalleled DMARC record generator and analyzer tool KDMARC. This remarkable tool is renowned for the proper implementation of DMARC policies along with DMARC record generation.
KDMARC is an incredible tool that fills following gaps of email authentication when it comes to DMARC which are:
Time Factor: KDMARC ensures that all the changes in DMARC policies are done within the span of hours rather than within the span of days. This feature not only increases the email deliverability but also, boosts the emails engagement rate of the organization.
Zero Coding Parameters: While changing any existing DMARC policy, a lot of coding job is skipped with the help of KDMARC. With the help of only a few clicks, records can be generated easily without involving any coding parameter.
Get Full Report of Your Email Channel: With KDMARC, you can get full threat analysis of you domain in no time. This innovative tool is proficient at presenting your domain’s summary of past 7 days complete report of threat incurred.
Detect and Defend Email Spoofing: KDMARC helps the user in detecting who is forging emails using its domain name.
KDMARC not only creates and observes the DMARC record but also, boosts email engagement rate by defending the organization against email spoofing. KDMARC is the most convenient tool to generate DMARC record and is easy to operate as well.
