Why this helps
List growth is hard to track consistently when counts are checked manually across different reporting periods.
- Review available list counts on a recurring schedule.
- Summarize changes for an explicit reporting period.
- Surface missing data assumptions before interpreting a trend.
Setup
Build it in a few focused steps.
- 1Connect ActiveTrail and ClickHouse once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, ask Notis to query available contact list count data for a specified period and summarize counts or changes.
- 4Choose a schedule trigger and the channel for run reports.
- 5Test with one real example and verify the records support the requested period.
Questions about this workflow
Does ClickHouse necessarily contain ActiveTrail contact list history?
Not necessarily. This workflow can summarize only list records or snapshots that are already stored and accessible in ClickHouse.
Can Notis calculate list growth without dated counts?
No. Comparing growth requires dated counts or equivalent historical records in the available data.
