The Email Engagement Report allows you to view the response to an email over a period of time relative to when the mailing was sent.  The report runs on a specific email and provides a count of the various reporting metrics over time.

The Email Engagement Report consists of multiple tabs that provide the response rate by a specific report metric.  You can access the different report metrics by clicking on the tabs.

To configure an Email Engagement Report, follow these steps:

1. Select an Email
2. Select the time interval to Report Over
   1. Fixed Time Period allows you to select a specific start and end date for the reporting interval
   2. Time Period Relative to Last Send Time allows you to select a reporting interval relative to the last send.
3. Select the Reporting Interval 
4. Click Run

The report will run in the background and the status of the report will update to Complete when it is ready.  To view the report, click on the name of the report.  If you prefer to export the report, use the Actions menu in the manager and the report will export in Excel.

The Consolidated Delivery Report (CDR) contains delivery and response metrics for all Email Tickets within your account over a configurable period of time.  All reporting data relates to the sends that occurred during the defined date range. This report may also be run across sub-client in order to produce one comprehensive report at the client level.

The CDR consists of default and optional reporting metrics.

The Consolidated Journey Report contains reporting metrics for all  journeys within your account over a configurable period of time.  All reporting data relates to the sends that occurred during the defined date range. This report can also be run across sub-clients in order to produce one comprehensive report of all journeys at the client level.

The Audience Performance Over Time allows you to view the performance of the selected audiences compared to the reporting for the send as a whole over a specific timeframe. The report allows you to track how your individual audiences are performing in order to gauge the engagement by audience. Once run, you can then take action on these metrics in the following ways:

• Identify key audiences to test messaging/offers/content into etc.
• Identify performance gaps for your most to least important audiences for planning
• Identify any potential programmatic metrics that will negatively affect engagement
• Proactively manage deliverability issues
• Identify any data quality issues 

Churn (often expressed as "churn rate") is the loss of existing subscribers over time. Along with list size and opt out rate, churn rate is a useful tool for measuring list health, particularly subscriber attrition versus subscriber acquisition.

In general, the lowest possible churn rate is the most desirable. A high churn rate coupled with a steady list size indicates that a sizeable proportion of the list is being lost and replaced with new subscribers over time. Reducing your churn rate means you're doing a better job of keeping your current subscribers.

For example, a 100% churn rate would indicate that every former subscriber was lost. A 0% churn rate would indicate that no subscribers were lost. A 50% churn rate would indicate that half of the prior subscribers were lost.
