What is the Email Open & Click Rate Calculator?
This calculator turns raw email campaign counts into rates. Delivery rate is delivered over sent. Open and click rates are measured against delivered emails, and click-to-open shows how many openers clicked. Compare the rates with your own earlier campaigns to see what is changing.
How it works
Delivered = sent minus bounced. Delivery rate = delivered / sent x 100. Open rate = opened / delivered x 100. Click rate = clicked / delivered x 100. Click-to-open rate = clicked / opened x 100. Any rate with a zero divisor shows zero.
How to use it
- Enter the number of emails sent and how many bounced.
- Enter the unique opens and unique clicks from your email tool.
- Read the four rates.
- Compare with your previous sends of a similar type.
Email Open & Click Rate Calculator — FAQ
Why can open rates be unreliable?
Some mail apps load images automatically, which can count an open that a person never made. Clicks are a firmer signal.
Should I use unique or total opens?
Unique opens count each person once, which is better for rates. Total opens count repeats and can exceed delivered.
What is click-to-open rate for?
It measures how compelling the email content was to people who opened it, separate from the subject line and sender.
