Email open rate checker
Enter your sent, opens and clicks to see open rate, click rate and click-to-open rate, with a plain note on why the open number is an estimate, not a count.
Open rate is an estimate: mail apps like Apple Mail can load the tracking pixel automatically, and others block it, so the number is inflated for some lists and hidden for others. Click rate is the reliable signal, because a click needs a deliberate tap.
Why open rate is an estimate
An open is recorded when a mail app loads a tiny invisible image. Since Apple Mail Privacy Protection launched in 2021, Apple loads that image for every message whether or not a person reads it, Gmail proxies it through its cache, and image blocking hides it entirely. So open rate is inflated for some lists and understated for others, which is why it is best read as a rough signal.
Click rate is the number to trust, because a tap is deliberate. If you want opens and clicks measured per recipient, with machine fetches separated out, email tracking does exactly that.
Track opens and clicks per recipient
directinapp records who opened and, more reliably, who clicked, without changing how you send. Clicks are reliable; opens are an estimate, and labelled as one.

Frequently asked questions
How do you calculate email open rate?+
Open rate is opens divided by emails sent, as a percentage. If 220 of 1,000 delivered emails were opened, that is a 22% open rate. Click rate uses clicks over sent, and click-to-open uses clicks over opens.
Is email open rate accurate?+
No. Open rate is an estimate. Apple Mail Privacy Protection loads the tracking pixel for every message whether or not anyone reads it, and other apps block it entirely, so open rate is inflated for some lists and understated for others.
Why is click rate more reliable than open rate?+
A click needs a deliberate tap, so it cannot be triggered by a mail app the way a pixel load can. That makes click rate and click-to-open the numbers to trust when comparing campaigns.
What is a good email open rate?+
Published benchmarks often sit between 15% and 30%, but they are less meaningful since automatic pixel loading began inflating opens in 2021. Compare your own click rate over time instead; it is measured the same way for everyone.
