    What is Email Deliverability?

    Email deliverability refers to the ability of your emails to reach recipients' inboxes successfully. It's determined by various factors including sender reputation, authentication protocols, content quality, and recipient engagement.

    Key Authentication Protocols

    SPF (Sender Policy Framework)

    Specifies which IP addresses are authorized to send emails for your domain.

    DKIM (DomainKeys Identified Mail)

    Uses cryptographic signatures to verify that emails haven't been tampered with.

    DMARC (Domain-based Message Authentication)

    Builds on SPF and DKIM to provide policy instructions for handling authentication failures.

    Factors Affecting Deliverability

    • Sender reputation and IP reputation
    • Email authentication (SPF, DKIM, DMARC)
    • Content quality and spam indicators
    • Recipient engagement rates
    • List hygiene and bounce rates
    • Sending frequency and volume
