Emailrep

EmailRep (emailrep.io) is an email reputation and intelligence API that provides structured risk assessment and contextual data about any email address. It returns a reputation score, risk classification, suspected usage type, and available intelligence signals including breach exposure, social media presence, and spam reporting history.

For OSINT investigators, EmailRep provides immediate contextual intelligence about an email address that goes significantly beyond simple validation. Within a single API call, investigators can determine whether an address is high-risk, has been exposed in data breaches, is associated with known spam or fraud activity, has an associated social media profile, and has been seen in security intelligence databases.

The reputation score and risk classification are particularly valuable for rapid triage. When processing large numbers of email addresses found during an investigation, EmailRep's risk scores allow investigators to prioritize accounts that warrant deeper analysis — high-risk addresses associated with fraud, spam, or breach data are immediately flagged for priority investigation.

The social media presence indicator reveals whether the email address is associated with accounts on major social platforms, providing immediate leads for social media OSINT without requiring manual searches across each platform. This cross-platform linkage is one of EmailRep's most valuable features for identity resolution.

Breach exposure data (sourced from HaveIBeenPwned and other breach databases) indicates whether the address has been compromised in known data breaches — and in which breaches — providing both risk context and investigative leads into what credential data may be available for the subject.

The suspected type classification (personal, business, disposable, role-based) helps investigators understand the nature of the account and its likely relationship to a specific individual.

EmailRep's API is free for limited use and available for higher volume with an API key. It integrates well into custom investigation workflows and OSINT automation pipelines.
