Check for an existing subscriber before follow-up
Avoid duplicate outreach decisions by checking an extracted email against Doppler before your team follows up.
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
Without a quick existence check, teams can waste time investigating duplicates or risk treating a known subscriber as new.
- Check subscriber existence without retrieving full details.
- Give your team a clear next step for existing and new contacts.
- Reduce duplicate handling during document intake.
