Learn how to build and use the segment growth report to gauge your audience's health week by week. The segment growth report provides a comprehensive view of each of your segments with the ability to hone in on growth, added and dropped members, and any trends or potential issues. Additionally, export the report to easily review data in more detail and take actionable steps with your segments.

Data can only be pulled from June 21, 2023 onwards.

Before you begin

You have 2 options for reviewing a segment growth report:

A report within an individual active segment.
Cards on your overview dashboard.

The cards on the overview dashboard do not show member profile information including event dates per individual profile. If you would like to see this information by member, use the full report in an individual active segment.

Additionally, note that this does not report on any profiles that were added and removed within the same day.

Using a segment growth report within an individual active segment

Navigating to the report

Head to Audience > Lists & segments and click on any existing segment. Note that this report is only available on segments and not lists.
Select Growth.

Customizing the report

To tailor the report to your marketing needs, you can customize the time range that the report looks at and pulls data from, as well as change how it displays in your charts. For example, you may want to look at a segment growth report for your VIP customers and their behaviors during slower-selling months.

Data can only be pulled from June 21, 2023 onwards.

Customizing date range

Open the dropdown menu under Date range. The initial selection is Last 7 Days. If you have used this report before, it can reopen with your saved date range.

Choose one of the following options:
Week-to-date
Month-to-date
Last 7 Days
Last 30 Days
Custom

If you select Custom, choose a start date and an end date in the date picker. The report updates once both dates are selected.

Custom has a max limit of up to 5 years and can only be pulled from when the data or segment was created. If you are attempting to pull too much or unavailable data, you will receive an error to redo your data parameters.

Customizing the time aggregation

Adjust how your data displays in your charts using daily, weekly, or monthly views.

Open the dropdown menu under View by.

Select Daily, Weekly, or Monthly, depending on your date range.

Daily is available for date ranges of 90 days or less. Weekly is available for date ranges from 8 days to 104 weeks (about 2 years). Monthly is available for date ranges of 31 days or more.

Refreshing the report

To see the latest available data, manually refresh the report. The Last updated timestamp next to the refresh icon shows when data was last loaded in your current view. Values may be delayed by up to 3 hours.

To refresh the report, click on the circular arrows icon. Your report timestamp will change to reflect this refresh update.

Reviewing the Segment size card

The Segment size card provides the ability to review the following over a certain date range:

Total segment size.
Total segment percentage change from the start to the end of the selected date range.
Segment growth.
Number of added profiles.
Number of dropped profiles.

The percentage change compares the segment’s size at the end of your date range with its size at the start. For example, if the segment grows from 1,000 to 1,200 members during your selected range, the percentage change is 20%.

Additionally, the total number of members added appear in a green status, while the total number of members dropped during this time period appear in a red status.

On the right-hand side of the card, you will see 2 graphs:

Segment growth over time.
Members that were added or dropped over time.

The Segment growth chart shows the total number of members for each daily, weekly, or monthly interval. By hovering over any of these plot points, you can review how many profiles existed at that point in time.

The Added / dropped members from segment chart shows the total number of profiles added and dropped (visualized as bars) during distinct points in time. Members added appear at the top of the chart in green, while members lost appear at the bottom half of the chart in red. Additionally, by hovering over any point in time, you can see the addition and subtraction counts for that date.

Reviewing the Segment Growth Details card

The Segment Growth Details card provides the ability to view segment size over time, with details on total members, changes, change percentages, etc.

This card’s table will contain the following columns:

Date The current points in time that are pulling in segment data.

The dates follow your View by setting: individual days for Daily, weeks for Weekly, and months for Monthly.

Total members The number of total, individual members in your segment at that point in time.
Net change The change in segment size during that interval: members added minus members dropped, including membership changes from merged or deleted profiles.
Net change % The net change as a percentage of the segment size at the start of that interval.
Added The number of individual members added at that point in time.
Dropped The number of individual members dropped at that point in time.

You can sort these columns by ascending or descending order by using the arrows to the right of each.

Further, you’re able to review older data or more pages of data by clicking between pages at the bottom or changing how many results display per page.

Handling reactivated segments If a segment is reactivated less than 90 days after it went inactive, no historical data is kept, and your report only displays data from the date of reactivation on. If a segment is reactivated equal to or more than 90 days after it went inactive, historical data is available prior to the inactive period and then resumes after reactivation.

Dates marked as inactive show a page icon and dashes instead of membership values, as shown in the example below.

Handling segments where definitions changed

If a segment definition changes at all during your report’s time period, an info icon appears next to the date this change occurred, as shown in the example below.

Click the arrow to expand that row and review the prior and current definitions.

Viewing specific added or dropped profile information

By clicking on any date in the main table view, you will be taken to the Added & dropped from segment section, where you can see:

Up to 1,000 records of profiles added or dropped during that interval.
All profiles’ personal information (e.g., name, email, phone number).
When a profile was added or dropped.

The profile information reflects the interval for the row you clicked. Deleted profiles are omitted from this detail view and its export.

By clicking on any number in the Added or Dropped columns in the main table view, you will be taken to the Added & dropped from segment section, where you can see the added or dropped members separately. Note that depending on what you clicked, you will only see one or the other (added or dropped).

Finally, when navigating to the Added & dropped from segment section from any column, you have the ability to adjust your report view directly.

Open Segment Change Activity and choose Added & Dropped, Added members, or Dropped members.

Exporting your aggregated data

On the main Segment Growth Details card, you can export the entire table of aggregated totals as a CSV. It includes Date, Total Members, Net Change, Net Change %, Added, and Dropped. It does not include definition-change details or the table’s icons and colors.

Export buttons are disabled if you do not have permission to export reports.

Click on Export CSV on the right of the card.
Look for the file in your browser or local downloads with the naming convention AcctName_SegmentName_DownloadDate.csv.

Exporting added or dropped member information

In the Added & dropped from segment section, you can export that particular set of member information as a CSV.

Click on Export to CSV on the right of the section.
Look for the file in your browser or local downloads with the naming convention AcctName_SegmentName_Profiles_DownloadDate.csv.

Your CSV contains the current view: Added & Dropped, Added members, or Dropped members. Select a different option before exporting if you want different information. Member exports are limited to 1,000 records.

Troubleshooting empty reports

If you see No data available, the segment had no members throughout the selected date range. Try the following:

If the segment is new or was recently updated, allow up to 3 hours for data to appear, then click Refresh.
If the segment had members at a different time, select a different date range. Otherwise, select Edit segment definition to review its criteria.

If there are issues happening and Klaviyo is unable to retrieve your data, you may need to refresh the report by clicking the Try again button that appears. This should reload your report once we are able to reprocess it.

Using segment growth cards in the overview dashboard

Navigating to the Starred Segment Growth card

Both segment cards use starred segments. Before adding a card, go to Audience > Lists & segments and click the star beside each segment you want to include.

Go to Analytics > Dashboards.
Open an existing overview dashboard. To create a new one, click Create Dashboard, enter a name, then click Create Dashboard in the dialog.
Click Add card.

If Add card is disabled, check its tooltip. You may lack permission to add cards, or the dashboard may already contain the maximum of 10 cards. If it has 10 cards, remove a card before adding another.

Within the library, select Starred Segment Growth, then click Add Data View.

Once you add this card to your report, it appears at the bottom by default.

Data can only be pulled from June 21, 2023 onwards. Even if your dashboard's data range includes time before this, your segment growth card will be limited in what data it can display.

Reviewing the Starred Segment Growth overview dashboard card

The Starred Segment Growth card on your overview dashboard lets you review total segment size and percentage changes, and segment growth, including added or dropped profiles, over time.

The card uses your dashboard’s date range. Klaviyo chooses daily, weekly, or monthly chart intervals based on that range.

The dropdown at the top defaults to All Starred Segments, but you can open this dropdown to select an individual starred segment to analyze.

Choosing a segment changes this card only. Other cards keep their own selections.

On the left-hand side of the card, you can review the total segment size at the end of the selected range and its percentage change from the size at the start. For example, growth from 1,000 to 1,200 members during the range is a 20% increase.

All Starred Segments adds together the membership counts for your starred segments. A profile in more than 1 starred segment is counted in each of those segments.

Additionally, the number of members added will appear as a total in a green status, while the number of members dropped during this time period, will appear as a total in a red status.

On the right hand side of the card, you will see 2 graphs:

One for segment growth over time.
One for members that were added or dropped over time.

The Segment growth chart shows the total number of members at each point in time, using daily, weekly, or monthly intervals based on the dashboard’s date range. Hover over a point to see how many profiles were in the segment then.

The Added / dropped members from segment chart shows the total number of profiles added and dropped (visualized as bars) during distinct points in time. Members added appear at the top of the chart in green, while members lost appear at the bottom half of the chart in red. Additionally, by hovering over any point in time, you can see the addition and subtraction counts for that date.

Reviewing the Starred Segments overview dashboard card

To add the Starred Segments card, click Add card, select Starred Segments in the library, then click Add Data View.

The Starred Segments card on your overview dashboard provides the ability to review:

Total segment size.
Segment percentage changes.
Segment growth.
Number of added or dropped profiles.

This card only shows information for starred segments; it cannot pull in non-starred segments for review. The time range and aggregated view of your report matches your overall overview dashboard time settings.

This card’s table contains the following columns:

NameName of your starred segment.
Total members The number of total, individual members in your segment at that point in time.
AddedThe number of individual members added at that point in time.
Dropped The number of individual members dropped at that point in time.
Net change The change in segment size over the selected range: members added minus members dropped, including membership changes from merged or deleted profiles.

You can also sort these columns by ascending or descending order by using the arrows to the right of each.

Viewing your complete segment growth report

By clicking on the name of the starred segment, you will be brought to the main active segment growth report for the section view of dropped and added member information.
