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.
