What is email reputation?
Email reputation is enrichment on the email address of a signup or login—disposable domain, age, and whether the address was previously tied to abuse—so fraud rules can raise scrutiny without treating every new inbox as fraud.
Where it helps
Naiza enriches events with email context, including validation and disposable-domain detection. Combine those signals with device linking and signup velocity to review account farms.
Keeping good customers moving
Privacy relays, corporate catch-alls, and brand-new addresses are common among real customers. Route them to REVIEW with device and velocity context instead of blocking every plus-address or .edu.
How Naiza applies it
Send the email on registration and login events. Naiza combines email enrichment with device context and lists so rules can route suspicious registrations to review.
Frequently asked questions
Answers about screening, risk signals, and Naiza integration.
What is an email reputation API?
It returns risk attributes for an email so signup rules can treat disposable or previously abusive addresses differently from typical consumer inboxes.
Should we decline disposable emails automatically?
Only if policy says so. Many teams REVIEW first, then list confirmed-abusive domains. A disposable inbox alone is not money laundering.
Is email reputation the same as KYC?
No. KYC verifies legal identity. Email reputation is a fraud-network signal on the identifier the user typed.
