What is Email Open Rate?
Share of delivered emails that were opened.
How to calculate it
Calculate Email Open Rate as: Emails opened / Emails delivered × 100. Pull the inputs from your connected data and track the trend over time in your dashboard.
Examples
Example 1
5,000 delivered, 1,400 opens -> 28%. Apple Mail inflates opens, so pair this with click-through rate.
Example 2
A newsletter to 8,000 subscribers gets 2,400 opens -> 30%. Opens hold steady but clicks fall, suggesting the content, not the subject line, needs work.
Why it matters
Email open rate is the share of delivered emails that are opened and indicates subject-line strength and overall list health. It is an early signal of deliverability problems and audience engagement trends. Since privacy features now inflate opens, it should be interpreted alongside click-through and conversion rather than on its own.
Benchmark context
Roughly 20-35% across industries; track the trend and pair with clicks, since Apple Mail Privacy Protection has made absolute open rates less reliable.
Common pitfalls
Apple Mail Privacy inflates opens; pair with clicks.
