    Email Deliverability

    The rate at which cold emails land in the primary inbox instead of spam or promotions.

    Definition

    Deliverability is the percentage of your sent cold emails that reach the primary inbox of the intended recipient.

    Month to month. Scoped on a 20 minute call.

    Why it matters

    You can write the best email in the world, but if it lands in spam your reply rate is zero. Deliverability is the single biggest driver of cold email ROI.

    How it works

    • Send from secondary domains, never your primary
    • Configure SPF, DKIM, and DMARC correctly
    • Warm mailboxes for 2 to 4 weeks before real sends
    • Cap each mailbox at 20 to 40 sends per day
    • Remove risky content and links, keep emails short and human
