Keep WhatsApp opt-in responders together in Amplitude
Use a specific interactive reply as the signal to add a known customer to your chosen cohort.
Trigger
Interactive Reply Received
Triggered when a customer taps a quick-reply button or selects an option from an interactive list message you sent.
Action
Update Amplitude Cohort Membership
Incrementally update cohort membership by adding or removing ids. this action allows you to: - add new ids to an existing cohort - remove ids from an existing cohort - perform multiple operations in a single request
Why this helps
Manually tracking customers who selected an opt-in choice creates avoidable follow-up and list upkeep.
- Keep a defined opt-in group current.
- Reduce manual cohort list updates.
- Tie the cohort rule to an explicit reply choice.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Amplitude once in the Notis portal.
- 2Create an automation and specify the exact opt-in reply, existing cohort, and customer ID to add.
- 3Pick Interactive Reply Received as the trigger and choose where run reports should go.
- 4Test with one real opt-in reply and confirm the identified customer appears in the cohort.
Questions about this workflow
Can this decide whether any reply counts as opt-in?
Define the exact reply that represents opt-in. The workflow should not infer consent from unrelated or ambiguous replies.
Does it create the Amplitude cohort?
No. It updates membership in an existing cohort that you specify.
