Email ROI
01 Definition
Email ROI meaning: The return earned from email marketing compared with what it cost to run.
Email ROI compares revenue attributed to email against the cost of running it, often shown as a ratio or percentage. A common formula is revenue minus cost, divided by cost. The result depends heavily on how revenue is attributed to email, which varies by tracking method and attribution window.

Why it matters
How Email ROI fits the work
It frames email spending as an investment with a measurable return, helping you justify budget and compare email against other marketing channels.
In context
If email drives 50,000 dollars in attributed revenue at a cost of 10,000 dollars, the ROI is 4 to 1, or 400 percent.
Practical note
Attribution choices swing the number a lot, so document your model and window; crediting email for sales it merely assisted can inflate the reported return.
