Why this helps
Audience validation gets skipped when it requires a manual workspace visit at the last minute.
- Catch audience issues before launch
- Support lightweight approval gates
- Reduce context switching
Setup
Build it in a few focused steps.
- 1Connect Customer.io once in the Notis portal.
- 2Create an automation and state the membership validation outcome.
- 3Tell Notis to identify the segment from the webhook request, retrieve membership, and flag empty or unexpected results.
- 4Pick the notis_webhook trigger and choose a report destination.
- 5Send one real validation request as a test.
Questions about this workflow
Can the request include an expected count?
Yes. Include it in the payload and ask Notis to compare it with returned membership.
Does this alter the segment?
No. It only retrieves membership for validation.
