Conversion Rate
Conversion rate measures how many delivered emails create the desired outcome: signup, purchase, or reply.
Conversion rate is the percentage of delivered emails that lead to your target outcome (for example, signup, purchase, reply).
Definition and examples
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 it matters
It matters because conversion rate tells you whether the email produced the business outcome you actually care about, not just opens or clicks.
How conversion rate is calculated
The basic formula is conversions divided by delivered emails, multiplied by 100. If 147 people convert out of 9800 delivered emails, the conversion rate is about 1.5 percent.
Common mistakes
A common mistake is optimizing opens/clicks while ignoring revenue. A common mistake is one landing page for all devices; not responsive. A common mistake is no post-purchase measurement; email often assists rather than closes.
