What is Email Open Rate?
Email Open Rate is the percentage of total emails opened compared to the total emails sent (minus bounced emails).
Formula:
Email Open Rate (%) = (Emails Opened ÷ Emails Sent) × 100
Example:
Emails Sent = 10,000
Emails Opened = 2,500
Open Rate = (2,500 ÷ 10,000) × 100 = 25%
