Check a contact before adding it to Doppler
Resolve the duplicate question at the handoff, with a simple existence check before a separate update decision.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Check Subscriber Exists
Checks whether a subscriber exists in an account.
Why this helps
A contact migration can create avoidable duplicate work when nobody checks whether the person is already in Doppler.
- Check subscriber existence by email without retrieving full details.
- Make a separate add or import decision using the result.
- Reduce manual lookups during contact handoffs.
Setup
Build it in a few focused steps.
- 1Connect ActiveTrail and Doppler marketing automation once in the Notis portal.
- 2Create an automation and describe the email to check and how to report the result.
- 3Choose the webhook trigger and send a request with the supplied email.
- 4Choose where run reports go, then test with one real contact.
Questions about this workflow
Does this check return full subscriber details?
No. This action checks whether a subscriber exists by email without retrieving full details.
Will it add a missing contact?
No. It only checks existence. Use a separate workflow with an appropriate create or import action if you decide to add the contact.
