List growth reporting reference

You will learn

Learn how to access and analyze your list growth report. For every list in Klaviyo, you can access a growth report that captures data regarding your list's changes over time. Use this tool to monitor business trends and expand your business.

Access your list growth report

1. To access your list growth report, head to your Lists & Segments tab and navigate into a given list.
2. Click List growth.
   

Analyze the sources of your list changes

Klaviyo assigns all list subscribers a $source property that reflects how the contact was added to your list. When someone unsubscribes, we will also track how they unsubscribed.

While it's possible to customize a given form's $source value, Klaviyo will otherwise track and use the following default values:

Default subscribe source values

• Unknown
  Subscriber source is non-identifiable.
• Back in stock
  Subscriber added via subscribing for back in stock notifications.
• Subscribe page
  Subscriber added via a subscribe page.
• Manually initiated
  Subscriber added via quick add or uploaded from a CSV file.
• Integration
  Subscriber added via opting in through an integration.
• API
  Subscriber added to a list via the Klaviyo API (i.e., subscribe profiles endpoint).
• Transferred membership
  Reflected when 2 profiles are merged, if the non-surviving profile was in the list before the merge.
• Merged profile
  Reflected when 2 profiles are merged, if both the non-surviving profile and the surviving profile were in the list before the merge.
• Embedded form
  Subscriber signed up using an embed form. 
• Flyout
  Subscriber signed up using a flyout form. 
• Modal
  Subscriber signed up using a pop-up form. 

Default unsubscribe source values

Customize a form's sign up source

If you're using a legacy form and want to customize the $source property, you can do this by making a small adjustment in your form's code.

List growth graphs

The total members and net membership change graphs provide insights into the health of your lists and net changes over time.

Total members graph

The total members graph tracks your list changes over a period. The cumulative number of subscribers in this particular period will be captured in the top number. Note that if you change your date range, this number will adjust to show the total number of subscribers in that period.

You can adjust the time frame at the top of the report via the Date range picker and visualize your data either by week or month by using the View by dropdown.

Additionally, by hovering over a bar in the graph, a popup will appear that provides the list size count for that point in time.

Net membership graph

The net membership graph shows both positive (green) and negative (orange) list size trends over time. The bars help to visualize the members lost and gained during a particular period. The top number will show the cumulative number of members gained or lost during this particular period. Note that if you change your date range, this number will adjust to show the number of losses or gains in that period.

Additionally, by hovering over a bar in the graph a popup will appear that provides the amount of members gained and lost during that particular point in time.

Subscriber sources table

The table breaks down the number of subscribers and how they were added to your list (i.e., the source) per month or week.

The totals section on the far right of the table will span the entire date range. However, the rest of the table will only show up to the 6 most recent time intervals from your date range. It will not show all time intervals.
