Email & Phone
Contact-level risk checks for communication, onboarding, and fraud triage.
Decide if a contact channel is reliable before sharing data or taking action.
Use cases: Outbound list hygiene • Account-recovery contact checks • Customer contact verification
Several of these pages share one keyword-and-pattern scorer with different overlays. Treat a “high risk” flag as a reason to pause, not as proof of fraud. For lists, use the bulk analyzers on the Trust tools index.
Email Validator
Syntax, mailbox plausibility, and disposable-risk for fraud and onboarding — not SPF/DKIM/DMARC diagnostics (use a mail-auth diagnostic for that).
Phone Checker
Format and context checks for numbers in support, marketplace, and payment threads — a triage layer before you call back or send codes.
Business Email vs Domain Match Checker
Classic BEC signal: does the sender domain line up with the company and website they claim? High impact for invoice and vendor threads.
Free Email vs Business Email Checker
Context check for when a free mailbox is a red flag (payments, legal, “official” requests) vs acceptable for consumer contact.
Disposable Email Risk Checker
Temporary inbox detection for signups, trials, and abuse-prone flows — reduce fake accounts before they hit your CRM.
Email Domain Reputation Checker
Heuristic domain trust for “should I trust mail from here?” — distinct from deliverability engineering (MX, SPF).
Email Bounce Risk Checker
List hygiene signal: malformed or risky addresses before a send — protects campaign quality, not SMTP server config.
Country Code Mismatch Checker
Cross-check phone country vs claimed location or company jurisdiction — common in fake support and remittance scams.
Display Name Spoofing Checker
Detects mismatches between displayed sender names and underlying contact patterns in phishing-style outreach.
Reply-To Mismatch Checker
Flags risky email threads where Reply-To addresses diverge from visible sender identity and expected workflow.
Sender Name vs Domain Mismatch Checker
Compares sender name claims with email domain context to catch business-email compromise style impersonation.
Phone Number Format Validator
Validates international phone-number structure and normalization quality before trust, outreach, or verification flows.
VoIP Number Risk Checker
Highlights VoIP-style risk cues for numbers used in onboarding, support, and high-risk payment conversations.
SMS Phishing Text Checker
Screens SMS content for smishing patterns such as urgent links, account panic language, and fake support voice.
OTP Request Legitimacy Checker
Checks one-time-password request wording for social-engineering patterns before users share verification codes.
Callback Scam Signal Checker
Evaluates callback requests for fake-helpdesk and fake-bank scripts that pressure victims to call attacker numbers.
Unreachable Contact Risk Checker
Flags contact records that look intentionally hard to reach or inconsistent across channels and business claims.
International Number Risk Checker
Assesses cross-border phone patterns against scenario context to identify suspicious communication setups.
