Click the Report dropdown on the Reports tab and choose Emails opened to see how many emails from your mailing were opened.
This report shows a pie chart with the percent and total number of emails opened, vs. emails for which there was no tracking data received.
| Tip: Not all emails marked "no data" were discarded by their recipients. Some recipients use email programs which do not support HTML email. These responses cannot currently be tracked. Other emails may have bounced due to incorrect addresses. |
To see more tracking data for individual recipients, see Filter contacts.
