Email Efficiency measures how effectively email marketing campaigns achieve their goals, such as engagement, conversions, or revenue, relative to the resources invested. It helps evaluate the performance and ROI of email marketing efforts.
How to Calculate Email Efficiency
Email Efficiency can be calculated using various metrics depending on campaign goals. A common approach is:
- Define key outcomes: Examples include clicks, conversions, or revenue generated.
- Measure resource input: Include time, budget, and tools used to execute the campaign.
- Calculate efficiency: Divide the outcome by the resource input (e.g., revenue per dollar spent, conversions per email sent).
For example, if a campaign generates $5,000 in revenue with a $500 budget, Email Efficiency is $10 revenue per dollar spent.
