Every signal that matters
A complete, AI-assisted verification engine — not just a regex. Here’s what runs on every check.
AI-assisted intelligenceAI
Smart typo correction
Edit-distance modelling suggests the intended domain — gmial.com → gmail.com — so real customers aren’t lost to a fat-fingered address.
Anomaly & gibberish detection
Bot-generated, random and nonsense local parts are recognised and scored down before they pollute your list.
Adaptive confidence scoring
Dozens of weighted signals are fused into a single 0–100 score you can threshold on for your own risk appetite.
Built for AI agents
Clean JSON responses and machine-readable, AI-crawler-friendly docs drop verification straight into your LLM pipelines, agents and automations.
Continuously improving data
Disposable and provider datasets are refreshed so detection keeps pace with new throwaway and temporary-mail services.
Deep validation pipeline
RFC syntax validation
Strict parsing and normalization catches malformed addresses instantly.
Domain & MX resolution
We confirm the domain exists and has mail exchangers (with A-record fallback).
SMTP mailbox probe
A real SMTP conversation confirms the mailbox accepts mail — without sending anything.
Catch-all detection
A random-address probe reveals accept-all domains so “accepted” never fools you.
Greylisting handling
Temporary deferrals are detected and retried automatically.
Quality & reputation signals
Disposable detection
Thousands of throwaway domains flagged, editable from the admin panel.
Role-account detection
info@, support@, admin@ and other shared mailboxes are surfaced.
Free-provider tagging
Know when an address is gmail, outlook, yahoo and similar.
Typo suggestions
Damerau-Levenshtein matching proposes the likely intended domain.
Gibberish scoring
Random-looking local parts lower the confidence score.
Built for scale
Single & batch API
Verify one address or millions through the asynchronous batch endpoint.
Webhooks
Get notified the moment a batch completes.
Per-plan rate limits
Predictable throughput with standard rate-limit headers.
Detailed reports
Filterable history, CSV export and usage analytics.
Dedicated IP probing
Verification workers run from clean IPs with correct rDNS.
