Open Rate Calculator
If you’re running email campaigns, your open rate is one of the most important metrics to track. It tells you the percentage of recipients who opened your email.
The Open Rate Calculator helps you quickly calculate this percentage, giving you instant insight into your campaign performance.
Open Rate Formula
Open Rate (%)=Unique OpensEmails Delivered×100\text{Open Rate (\%)} = \frac{\text{Unique Opens}}{\text{Emails Delivered}} \times 100Open Rate (%)=Emails DeliveredUnique Opens×100
Where:
- Unique Opens: The number of recipients who opened your email at least once.
- Emails Delivered: Total emails sent minus bounced emails.
Example Calculation
If you sent 5,000 emails and 4,500 were delivered, and 1,800 people opened the email: Open Rate=1,8004,500×100=40%\text{Open Rate} = \frac{1,800}{4,500} \times 100 = 40\%Open Rate=4,5001,800×100=40%
Your open rate is 40%, which is above average for most industries.
