What is Open Rate?
The percentage of email recipients who open your email, used as a measure of how well your subject line and sender name are performing.
In plain English
Open rate is typically the first metric marketers look at when evaluating email performance. Industry averages vary widely — B2B newsletters often see 20-30% open rates, while promotional e-commerce emails might see 15-20%. Open rate matters because an email that isn't opened can't drive any action. However, Apple's Mail Privacy Protection has made open rates less reliable since 2021, so it should be considered alongside click rates and conversions rather than in isolation.
