A Marketer’s Guide to DMARC, SPF, and DKIM

Email Authentication Strategies

Three abbreviations—DMARC, DKIM, and SPF—are frequently mixed up with one another. Additionally, these are acronyms that every marketer needs to be familiar with. You invest a lot of money in your email marketing strategy. But what if you are unable to get your emails to your subscribers’ inboxes? Not only is it terrible for business, but it can also be discouraging, annoying, and outright irritable.

Fortunately, there are approaches to guarantee that recipients see your emails in their inboxes.

Email Authentication Strategies and How They Can Help You

The DMARC Protocol

You can implement a policy called DMARC (short for Domain-based Message Authentication, Reporting & Conformance) to safeguard the email reputation of your domain. DMARC is the tool for you if you have a custom domain like [business name] and want to ensure that only emails coming from your domain are received and viewed by recipients!

DMARC and its Myriad Benefits

  • DMARC makes it possible for domain owners to take ownership of their domain by instructing how recipients should respond to email messages that fail authentication for either SPF or DKIM (explained below).
  • DMARC has positive impacts on email deliverability rates by helping email service providers establish trust in sending sources.
  • DMARC reports help domain owners gain valuable insights into their email activities, sending sources, and deliverability, helping them actively monitor their efforts and understand authentication failures.

DKIM for Signing Messages

The email authentication standard known as DKIM (short for DomainKeys Identified Mail) enables an organization to assume accountability for a message by placing a digital signature on outgoing communications. A DKIM signature on an email from your business lets recipients know it is from you.

The Advantages of Using DKIM

  • DKIM is a widely supported email authentication protocol that is practiced and encouraged by most ESPs to ensure safer email transactions and the process of setting it up is simple and convenient. 
  • DKIM along with DMARC helps minimize the risk of phishing and spoofing attacks by ensuring every outgoing email has a DKIM signature appended to it that is used by receiving MTAs to retrieve and match against the public key in the sender’s DNS. 
  • DKIM protects against Man-in-the-middle attacks by ensuring that email messages are not changed by third-party interventions during message transmission.

SPF for Sender Authorization

Sender Policy Framework, as the name suggests, is a protocol that defines a policy for email senders by maintaining a live list of authorized sending sources in the sender’s DNS, implying that they are the sources that are permitted to send emails on behalf of the domain. Let’s explore how this can be beneficial: 

The Positives of Implementing SPF 

  • Just like DKIM, SPF can also be used in combination with DMARC or together with both DMARC and DKIM for enhanced protection to take your email’s security to the next level. 
  • SPF is beneficial for senders who want to allow certain IP addresses to send messages from their domain while blocking out others. 
  • SPF along with DMARC can also be used as strong defensive mechanisms against email-based threats like spoofing and phishing.

Trust is currency when it comes to email marketing since the more your sender address is trusted, the higher the probability of your emails being opened. Organizations looking to upscale their email security, as well as marketing efforts, should waste no time configuring a DMARC analyzer today to boost the effectiveness of their campaigns.
