If you manage email campaigns, you already know that list size alone does not pay the bills. True campaign profitability depends on a delicate chain of engagement and conversion metrics: how many people open your email, how many click your links, and how many ultimately complete a purchase.
To help you forecast your returns before hitting “Send,” we built the Email Marketing Revenue Estimator. This free interactive tool allows you to plug in your core metrics and instantly view a complete revenue and performance breakdown.

Understanding the Calculation Breakdown
Beyond top-line revenue, the calculator features a Calculation Breakdown section to give you deeper campaign insights:
