What is DMARC?
DMARC – an open standard enabled on 70% of the world’s inboxes and also DMARC is the best solution that lets businesses protect their emails from illegitimate usage and cyber attacks.
DMARC is built upon two other authentication protocols: One of which is SPF (Sender Policy Framework) and another one is DKIM (DomainKeys Identified Mail). You should have SPF and DKIM on your Envelope From and Friendly Form domains before proceeding with DMARC.
DMARC (aka Domain-based Message Authentication, Reporting, & Conformance) DMARC is an email authentication standard that based on SPF & DKIM protocols, letting customer to get visibility into how their email domains are used, allowing to catch all the fraud emails that send from unauthorized server, besides this benefits it increases email deliverability, gives companies a trust high level that customers wish to communicate without receiving a fraud from them, makes companies not to lose their money on phishing, sending an email to the recipients inbox is also one of the advantages of using DMARC.
DMARC record example
_dmarc v=DMARC1;p=reject;sp=none;pct=100;adkim=r;aspf=r;rua=mailto:[email protected]; ruf=mailto:[email protected];rf=afrf;ri=86400;fo=1
SPF (aka Sender Policy Framework) allows domain owners to choose which email addresses one can send an email from with their domain- it is the “From” header of the email. SPF can catch the unauthorized servers where a hacker sends an email from, furthermore, it protects a real message from the domain owner. With SPF a receiver can consider the email authentic.
SPF record example
example.com v=spf1 mx ip4:1.1.1.1/32 include:_spf.example.net -all
DKIM (aka DomainKeys Identified Mail) DKIM is an email authentication standard that associated with a signature checker that a sender inserts into the email message. Sender’s cryptographic signatures are designed for receivers to verify by using DNS-hosted public keys. If the signature is correct and checked DKIM identifies it as a reliable domain-level.
DKIM record example
example._domainkey v=DKIM1; k=rsa; p=public_key
The DMARC protocol allows senders to publish policy records to manage the emails reach on inbox or spam box, or rejecting. The policy features that DMARC enables are:
- P=none – None is monitor mode, that doesn`t prevent emails from getting into the spam box but only monitors them.
- p= quarantine – Helps you send fraud email to the spam box.
- P= reject – reject policy is what your company need to achieve high email protection. It doesn’t allow illegal emails to reach the receiver inbox or even spam box.
Build your DMARC record in less than 1 minutes with the help of our advanced email protection tools!
- Go to the EasyDMARC website and generate your DMARC record with DMARC generator.
- If You have multiple domains you need to generate your DMARC text record in your DNS for each sending domain.
- Set the DMARC policy to “none” indicating DMARC’s “monitor” mode.
- With DMARC in monitor mode, you can gather the information on your entire email ecosystem and see who is sending email on behalf of your brand, what emails are getting delivered, and what emails are not.
- Add a TXT record to your DNS service, it should be like this:
