Open rate in an email marketing campaign is calculated by dividing the number of opened email messages by the substraction of sent email messages minus bounced email messages. This is the formula to calculate open rate:
| Open Rate= | Opened Email Messages |
| Sent Email Messages - Bounced Email Messages |
If 450 emails were sent, 200 emails were opened, and 30 emails bounced, then the open rate gets calculated like this:
| Open Rate= | 200 |
| 450 - 30 | |
| Open Rate=0,4761 (47,61%) | |
