Check a customer domain reputation after Addresszen validation
Review domain reputation before a validated customer becomes a deliverability risk.
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 correct delivery location does not reveal whether the associated domain is listed on spam blocklists.
- Adds a reputation signal to location validation
- Surfaces DNSBL matches for human review
- Helps protect outbound deliverability
Setup
Build it in a few focused steps.
- 1Connect Addresszen and Emaillistverify; the webhook must contain the real Addresszen result and the customer domain.
- 2Create an automation instructing Notis to check that supplied domain against blacklists after the location result is received.
- 3Select the Notis webhook trigger and send one real domain example.
- 4Choose a report destination and test the response before acting on it.
Questions about this workflow
Can this check an IP instead?
Yes, if your supplied payload contains an IPv4 or IPv6 address; otherwise provide the domain.
Does a blacklist result automatically reject the customer?
No. It reports the Emaillistverify result for your stated review or decision process.
