Master Email Deliverability with Proper Email Authentication

Email authentication improves email deliverability. Using email authentication the conveyance and believability of your advertising emails by executing conventions that check your domain as the sender of your messages.

While email authentication doesn’t guarantee inbox placement, it significantly improves your chances. It acts as your first line of defense against spoofing, phishing, and spam-related issues that can damage your sender reputation.

In this blog, we focus on the three key email authentication protocols: SPF, DKIM, and DMARC. Each serves a different function, but all work together to protect recipient inboxes and ensure your emails come from a trusted source.

1. Sender Policy Framework (SPF)

SPF allows domain owners to specify which mail servers can send emails on their behalf. It helps receiving servers verify that incoming messages come from authorized sources, reducing the risk of forged emails and spam.

2. DomainKeys Identified Mail (DKIM)

DKIM confirms that an email’s content hasn’t been tampered with in transit by using cryptographic signatures. The sender’s server attaches a digital signature to each email, and the recipient’s server verifies it using the public key stored in DNS. If the keys match, the system recognizes the email as authentic.

How DKIM Works

If the content hasn’t been altered, the email passes DKIM verification.

DKIM authenticates email by allowing the sender to take responsibility for a message in a way the recipient can verify. It uses public key cryptography to confirm that an authorized mail server sent the message. This process helps detect forgery and prevents the delivery of harmful emails like spam.

• The sender’s Mail Transfer Agent (MTA) creates a signature based on the email content.
• The MTA adds the signature and sends the email.
• The recipient’s server fetches the sender’s public key from DNS and validates the signature.

3. DMARC (Domain-based Message Authentication, Reporting & Conformance)

DMARC builds on SPF and DKIM to give domain owners control over unauthenticated emails. It lets you instruct receiving servers on how to handle suspicious emails—whether to quarantine, reject, or report them. DMARC also provides insights into authentication performance and misuse.

Why SPF and DKIM Work Better Together

SPF and DKIM offer value individually, but when combined, they provide a more robust authentication framework. Together, they make it much harder for attackers to impersonate your domain and get past spam filters.

Authentication Strengthens Sending Reputation

ISPs and mailbox providers track domain reputation based on authentication. When you properly configure SPF, DKIM, and DMARC, ISPs recognize your domain as a trustworthy sender. A positive reputation improves your chances of landing in the inbox and accelerates how quickly receiving servers accept your mail.
