email conversion rate?
Recipient-based email conversion rate measures delivered recipients who place an attributed order, divided by delivered recipients for that send.
Some platforms report orders per delivery or conversions per click. Those rates are not directly interchangeable with unique converting recipients.
02 / The measurementA clear formula.
A clear formula.
A useful comparison.
Email CVR =Delivered recipients with an attributed order ÷ Delivered recipients × 100
Read the result in context.
Compare the same message type, attribution model and country. Keep automated flows separate from broad campaigns.
Document the comparison.
Keep the reporting dates, population, exclusions and calculation with every result. Show underlying counts as well as the average or rate, so a small sample does not look more conclusive than it is.

Real stories.
Clear measurement limits.
We have not verified a published Clerk customer case with a quantified email conversion rate result matching this page’s definition.
What would count as useful evidence?
A case reporting delivered recipients with an attributed order and delivered recipients, with the time window and comparison method. General revenue growth or a related engagement metric does not establish this result.
Customer stories describe individual implementations. They are not industry benchmarks, guarantees or standardized causal tests.

clarity.
How do I calculate email conversion rate?
Delivered recipients with an attributed order ÷ Delivered recipients × 100. 1% of delivered recipients placed an attributed order. Count a recipient once even if they ordered twice.
What should I check before comparing results?
Some platforms report orders per delivery or conversions per click. Those rates are not directly interchangeable with unique converting recipients.
What is a good email conversion rate?
Compare the same message type, attribution model and country. Keep automated flows separate from broad campaigns.
Does a higher attributed result prove incremental growth?
No. Attribution connects an interaction with an outcome under a reporting rule. To estimate what a change added, compare randomly assigned treatment and control groups using the same eligible population and a predefined measurement window.
