Review vendor domain reputation from invoices
When an invoice introduces a new supplier, check its extracted domain against DNS-based blacklists before relying on it for email communication.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Check Blacklists
Checks an IP address or domain against DNS blacklists; limited to 10 requests per second.
Why this helps
A questionable supplier domain can raise doubts about whether invoice-related messages are safe to trust or use for follow-up.
- Check an invoice-derived domain against multiple DNS-based blacklists.
- Keep the reputation result beside the invoice context.
- Make supplier communication review easier to track.
Setup
Build it in a few focused steps.
- 1Connect Affinda and Emaillistverify once in Notis.
- 2Create an automation in Automations, New Automation, or tell Notis the outcome in plain language from any channel.
- 3Ask Notis to check the vendor domain in each incoming Affinda invoice extraction against DNS-based blacklists and report the result with invoice context.
- 4Choose a Notis webhook as the trigger and select where run reports should go.
- 5Send one real invoice extraction and review the domain reputation result.
Questions about this workflow
What input does the blacklist check need?
It checks an IP address or domain. This workflow uses a vendor domain included in the Affinda invoice extraction payload.
Does a blacklist result prove an invoice is fraudulent?
No. It is a reputation signal for a domain or IP and should be reviewed with the invoice and your normal supplier checks.
