Campaign statistics let you measure the effectiveness of your email campaigns. For each campaign you can see:
the recipients you emailed
how many opened your messages
how many clicked on your links
how many unsubscribed
any email address issues listed in the Bounces section
To view campaign statistics:
Click the Email Marketing button on the left sidebar.
Click either the campaign name or the View button to open the campaign's statistics.
On the statistics page you will find three sections:
General info: General information about the campaign.
Performance Stats: An overall picture of the campaign's reach and engagement.
Recipients: All recipients the campaign was sent to, grouped by category.
