Email Intelligence
Email is one of the strongest indicators of signup quality. SiftlyAPI evaluates domain reputation, email patterns, and registration history to assess trustworthiness.
What We Analyze
Domain Reputation
Whether the email domain is a known business, personal, or disposable provider
Email Pattern
Professional patterns like first.last@company.com score higher than random strings
Domain Age
Newly created domains are riskier — established domains indicate legitimacy
Domain Classification
Business, personal, and disposable domains are treated differently
Domain Types
Disposable
HIGH RISK
Temporary email services like guerrillamail, tempmail
Personal
LOW-MEDIUM
Consumer providers like Gmail, Yahoo, Outlook
Business
TRUSTED
Company domains with professional email patterns
Domain Age Impact
| Domain Age | Risk | What It Means |
|---|---|---|
| < 30 days | High | Very new domain — often associated with spam |
| 30-90 days | Medium | Recently created — may be legitimate but unestablished |
| 90 days — 5 years | Low | Established domain — indicates legitimacy |
| 10+ years | Low | Long-standing domain — highly trustworthy |
Best Results
For the most accurate email analysis, always pass the full email address — not just the domain. This allows SiftlyAPI to evaluate both the local part pattern and the domain reputation together.
