What is Email Deliverability?

  • Email Authentication Overview
    • Email authentication is a crucial technical standard ensuring your identity is verified, preventing your emails from being flagged as spam or phishing attempts.
    • Without email authentication, malicious individuals can manipulate their email addresses to mimic legitimate senders and deceive recipients.

    Implementation by the IT Team

    • Your IT team is responsible for implementing email authentication.
    • They configure mail servers to allow a recipient's email server to check incoming messages against established rules.
    • Gmail and Microsoft typically set up these policies during mailbox configuration, but it's advisable to confirm, especially before large email campaigns.
    • If using Exchange, coordinate with your IT team to ensure SPF and DKIM are set up before sending mailings.

    Email Authentication Standards: DKIM, SPF and DMARC

    • DKIM (Domain Keys Identified Mail)
      • An authentication protocol used by email receivers to verify the sender's legitimacy.
      • Utilizes a specialized key unique to each sender, assuring the recipient's mailbox of the message's authenticity.
        • Positively contributes to your anti-spam score.

    • SPF (Sender Policy Framework)
      • Email validation system preventing spam and authenticating senders.
      • Checks the sender IP address to ensure it's authenticated and verified.
        • Incoming servers reject emails from unlisted SPF records, assuming they are spoofed or illegitimate.

    • DMARC (Domain-based Message Authentication, Reporting & Conformance)
      • Another authentication protocol enabling senders and receivers to report potentially fraudulent domains.
      • DMARC policies indicate authenticated messages via SPF and Bounced Email Notifications

    When you send an email and it is rejected by your prospect's email server, you receive a bounced email notification. There are two primary types of bounces: hard bounces and soft bounces, the details of which are explained in the FAQ.
