Keep communication preferences tidy without a weekly chore

A quarterly review can catch confirmed preference drift in one planned pass, leaving your day-to-day attention for active conversations.

Trigger

Recurring schedule

Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

Action

Update Contact Attributes

Tool to update attributes of an existing contact. use after confirming the contact exists and you need to modify its custom attributes.

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.

Questions about this workflow
