List Size Over Time Report

What Is the List Size Over Time Report

The List Size Over Time Report displays the size of a given list over a period of time. It tracks both the total number of subscribers on the list as well as the email status of these subscribers (unsubscribed, undeliverable, etc). This report functions better over longer periods of time, so use the report to measure list growth over periods of 1 month or longer. Shorter time spans may reflect inconsistent results due to the smaller time frame.

Note: A subscriber may rarely move in and out of Bounced and Held statuses. For example, if a full inbox causes a message to bounce but a later attempt to send is successful, or if a held subscribers clicks a link in an old email. If this happens, the Bounced and Held values for a time period can change over time.

The List Size Over Time Report contains a table and a graph to illustrate the data on the report. The table contains the following information:
