EmailRep is an email address reputation and threat-intelligence API operated by Sublime Security, Inc. It crawls and enriches data across social media profiles, professional networking sites, dark-web credential leaks, data breaches, phishing kits, phishing emails, spam lists, open mail relays, spam traps, domain age and reputation, and email-deliverability signals to predict the risk associated with any email address. The free, JSON-over-HTTP REST API returns a reputation, a suspicious flag, a references count, and a detailed signal block (blacklisted, malicious_activity, credentials_leaked, data_breach, domain_reputation, deliverable, spoofable, profiles, and more). A POST /report endpoint lets analysts contribute observations of malicious email behavior back into the reputation graph.

Email reputation and threat-intelligence REST API. GET /{email} returns a reputation verdict (high/medium/low/none), a suspicious flag, a references count, and a detailed signal block covering blacklisting, malicious activity, credential leaks, data breaches, domain age and reputation, deliverability, MX validity, SPF/DMARC posture, spoofability, free-provider/disposable status, and known online profiles. POST /report lets authenticated callers report an email address as malicious (BEC, phishing, fraud, account takeover, maldoc, etc.) so the signal feeds the reputation graph. Authentication is via a Key header issued from emailrep.io/key. Free tier: 250 queries/month, 10/day; Commercial tier: 1,000 queries/month at $20/month with no daily limit; Enterprise: high-volume custom plans with SLA.
