Email Open Rate Calculator

Open rate shows how many recipients opened your email. It’s useful for judging subject lines, sender reputation, and audience fit. Enter opens and total emails sent to compute the percentage. Filter out hard bounces when possible so the rate reflects actual deliveries. Use open rate alongside click and conversion to get the full picture.

Tip

Exclude hard bounces from “sent” if you track them.

FAQs

What is a good open rate?

Ranges widely by list source and industry. Many lists see 15–30%.

Why did my open rate drop?

List fatigue, poor subject lines, deliverability issues, or sending to the wrong audience.

Do privacy changes affect open tracking?

Yes. Some clients prefetch images, which can inflate or mask opens. Use clicks and conversions too.
