β Frequently asked questions
Why check domains separately from IP reputation?
Many content filters score URL/domain reputation independently from sending IP reputation.
Can parked domains trigger URIBL issues?
Yes. Misconfigured parking or redirect chains can create reputation exposure.
Does one bad subdomain affect the parent domain?
It can, depending on zone policy and abuse severity.
Should I rotate domains to bypass listing?
Bypassing without remediation increases long-term trust and policy risk.
What is next after URIBL clearance?
Re-validate campaign links, auth posture, and sending patterns.
