Running the Report

The list growth report enables you to efficiently measure how fast your subscriber base is growing.

Selecting Lists

You may run list growth reports for a specific list, a combination of lists, or for your entire account using the filtering dropdown:


Reporting Timeframes

You can adjust the roll-up periods for the presentation of the data:


Report Breakdown

The bar graph on the report measures new contacts added per reporting timeframe by source.


The table below the chart measures new contact acquisition, churn reasons, and net growth of active contacts.

New ContactsNew email addresses that joined the list during the reporting period.
UnsubscribedSubscribers who unsubscribed during the reporting period.
SPAM ComplaintsSubscribers who complained during the reporting period.
Bounced EmailsSubscribers who hard bounced during the reporting period.
Deleted ContactsSubscribers who were manually deleted during the reporting period.
Active ContactsSubscribers on your select list(s) who were not unsubscribed, complained, bounced, or deleted during the period.

Tracking Subscriber Source

The list growth report also provides a breakdown of acquisition sources if you're passing a value for the source field with each new subscriber:


In order to track subscriber source, you'll need to pass a value for the source field when new subscribers are added to your list. Here's an example of this in practice using the subscribeToList endpoint of our Javascript library:

_rejoiner.push(['subscribeToList', {
  'email': '[email protected]',
  'list_id': 'foobar',
  'first_name': 'Name',
  'source': 'modal_capture',
