Email marketing delivers the highest ROI of any marketing channel—but only if you measure it correctly. Understanding your metrics helps you optimize campaigns, justify budget, and demonstrate business impact. This guide covers the essential metrics every email marketer must track.

Companies that calculate email ROI are 3x more likely to increase their email marketing budget.

The Metrics That Matter

Not all metrics are created equal. Focus on the metrics that directly tie to business outcomes.

Primary Metrics to Track

Open Rate

Measures subject line effectiveness and list engagement.

Click-Through Rate

Shows how many recipients took action after opening.

Conversion Rate

Tracks how many clicks resulted in desired actions.

Revenue Per Email

The ultimate metric—total revenue divided by emails sent.

Calculating Email ROI

The formula is simple: (Revenue - Cost) / Cost x 100 = ROI%. Track all costs including tools, creative, and list rental. For e-commerce, use trackable links to attribute revenue directly to email campaigns.
