Why this helps
Contact preferences age quietly, then create confusion when a message no longer matches what someone expects.
- Batch low-urgency preference maintenance into one review.
- Keep confirmed changes visible in Wati.
- Reduce avoidable one-off cleanup tasks.
Setup
Build it in a few focused steps.
- 1Connect OneSignal and Wati to Notis once in the portal.
- 2Create a scheduled automation with a prompt to compare available verified subscription preferences and update matching existing Wati contact attributes when changes are confirmed.
- 3Set a quarterly schedule and choose a channel for run reports.
- 4Test with one known preference change and verify the contact update.
