The Subscriber Lists dataset shows how many people belong to each list and how that membership changes over time. It is available when a connected source supplies list or segment membership data. Use the Subscriber widget to see these changes on a dashboard.
Where the data comes from
Section titled “Where the data comes from”Your marketing automation or customer data platform defines who belongs to each list. The selection rules stay there. SEINō pulls a unique identifier for each member and takes a daily snapshot, so it can count membership without needing names or email addresses for this dataset. See the Integrations overview for available sources and their setup guides.
Dimensions
Section titled “Dimensions”Dimensions let you group or filter list results.
| Dimension | What it shows |
|---|---|
| Date | Date of the recorded list membership data. |
| List | Name of the list or segment. |
Metrics
Section titled “Metrics”| Metric | What it counts |
|---|---|
| Members | People in the list on that date. |
| Members delta | Net change since the previous daily snapshot. |
| Members in | People who joined the list. |
| Members out | People who left the list. |
How list changes are counted
Section titled “How list changes are counted”SEINō compares each daily snapshot with the previous one. Members in counts people present now who were absent before; Members out counts people who were present before but are absent now. Members delta is members in minus members out. These measures describe changes to list membership, which can include more than unsubscribes.
