Email open rate is the percentage of people who received an email and opened it.
Open rates vary widely, and depend on a range of factors. Some factors that affect email open rates include:
- The industry of the email sender
- From name
- Subject line
- Time of day
- Day of the week
Despite the variation in open rates, a good open rate is typically in the 20-40% range.
The email open rate is calculated by dividing the number of emails opened by the total number of email messages sent (excluding bounced emails).
