Check Addresszen contacts before adding them
Know whether a validated contact is already in Doppler before creating another subscriber record.
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
Duplicate checks often happen late, after a contact has already been passed between tools.
- Prevents avoidable duplicate subscriber work
- Returns a direct existence decision
- Keeps the validation handoff auditable
Setup
Build it in a few focused steps.
- 1Connect Addresszen and Doppler marketing automation once in Notis.
- 2Create an automation that checks subscriber existence for an email in an Addresszen webhook payload.
- 3Describe that the payload contains the validated email and Doppler account name, and return the result for follow-up decisions.
- 4Choose the Notis webhook trigger and a report channel.
- 5Send one real Addresszen result to verify the check.
Questions about this workflow
Does this action add a subscriber?
No. It only checks whether the supplied email exists in the specified Doppler account.
Can Notis infer the email from an address?
No. Your webhook payload must include the email that should be checked.
