What is SPF?
Sender Policy Framework (SPF) is used to authenticate the sender of an email. With a perfect SPF record in place, Internet service providers would be able to verify that a mail server is authorized to send email for a specific domain.
An SPF record is a DNS TXT record that contains the list of IP addresses that are allowed to send emails on behalf of your domain. At the organizational level, your IT administrator can access them and update them.
What is DKIM?
DKIM, or DomainKeys Identified Mail is an email authentication method used for digital signature to let the receiver of the email know that the message was sent via an authorized owner of a domain.
DKIM protocol uses a cryptographic signature that is added to the message and verifies that the email is authentic and has not been altered in the transit. Once the receiver gets the email, it helps determine that the content has not been modified and nobody is trying to impersonate the brand.
What is DMARC?
Domain-based Message Authentication Reporting & Conformance (DMARC) is an email security protocol that verifies email senders by building on the Domain Name System (DNS), DKIM, and Sender Policy Framework (SPF) protocols.
DMARC requires DKIM or SPF in place for a domain to get a DMARC record to be published in the DNS. The DMARC policy process enables the email domain’s policy to be shared and authenticated once the SPF and DKIM status has been checked.
What are DMARC Policies?
There are three policies, which are:
None: this is signed by ‘p=none’, the receiving server will take no action on an unqualified email.
Quarantine: this is signed by ‘p=quarantine, the receiving server will quarantine any unqualified email. As a result, email might go to spam.
Reject: this is signed by ‘p=reject, the receiving server will deny unqualified email messages.
Why do SPF, DKIM and DMARC matter for my email campaigns?
With evolving technical threats and rise in cybercrime, email authentication plays a viral role for any organization and its users. Not only preventing phishing attacks on your users, email authentication also protects your brand reputation. Enhanced email security will also help organizations comply with various regulations.
