Conversion Rate

Conversion rate is the percentage of delivered emails that lead to your target outcome (for example, signup, purchase, reply).

Definition & Examples

What is Email Conversion Rate?

Email conversion rate measures the percentage of delivered emails that result in a desired action or outcome. Unlike open rate or click-through rate, conversion rate tracks completion of your campaign's primary objective, whether that's making a purchase, signing up for a service, downloading content, or any other business-critical action.

This metric represents the ultimate effectiveness of your email marketing efforts by directly connecting email engagement to business results and revenue generation.

Why conversion rate matters

• Revenue connection: Directly links email marketing activities to business outcomes and financial results

• ROI measurement: Provides clear data for calculating return on email marketing investment

• Campaign effectiveness: Reveals which campaigns, segments, and strategies drive actual business value

• Funnel optimization: Identifies friction points between email engagement and goal completion

• Resource allocation: Guides budget decisions between acquisition, retention, and re-engagement efforts

How conversion rate is calculated

Basic conversion rate formula

Email Conversion Rate = (Total Conversions ÷ Total Delivered Emails) × 100

Alternative calculation methods

Post-click conversion rate:
(Total Conversions ÷ Unique Email Clicks) × 100

Segment-specific conversion rate:
(Segment Conversions ÷ Segment Delivered Emails) × 100

Time-based conversion rate:
(Conversions within X days ÷ Delivered Emails) × 100

Example calculation

• Campaign sent: 10,000 emails

• Successfully delivered: 9,800 emails

• Total conversions: 147 purchases

• Conversion rate: (147 ÷ 9,800) × 100 = 1.5%
