Email ROI
Return on investment for email: how much you earned compared with what you spent.

In practice
ROI = (revenue − cost) ÷ cost × 100. Count every cost: platform fees, list acquisition, verification, design and staff time. Revenue must be attributable to the email, which is the hard part when customers also see other channels.
Example
Spend 2,000 and earn 5,000 attributable revenue: ROI is (5,000 − 2,000) ÷ 2,000 = 150%.
Verification and sending
Verification is a cost that usually reduces other costs: fewer bounces, and less spent on platform fees for dead contacts.
