# MailVeri

> MailVeri is a high-throughput, enterprise-grade email verification SaaS platform designed for sales outreach, lead generation pipelines, marketing automation, and AI agents. It delivers 99%+ deliverability accuracy with pay-as-you-go pricing starting at $0.0002 per email (up to 90% cheaper than legacy providers), featuring credits that never expire and zero monthly subscriptions.

## Overview & Core Capabilities

MailVeri operates a dual-engine email validation architecture:
1. **Real-Time Single Verification API**: Sub-second synchronous verification specialized for point-of-capture form validation, lead scoring, CRM triggers, and AI agent tool calling.
2. **High-Throughput Bulk Verification Daemon**: Scalable async processing for massive list uploads (CSV, Excel, TXT) supporting up to 1,000,000 emails per batch with automated webhook dispatch upon completion.

### Comprehensive 9-Step Verification Suite
- **Syntax & RFC 5322 Validation**: Rejects malformed addresses, illegal recipient delimiters, and invalid characters.
- **DNS & MX Record Lookup**: Verifies destination mail exchange records with fallback cache.
- **Deep SMTP Direct Handshake**: Direct carrier handshake verifying mailbox existence without delivering actual emails.
- **Catch-All Domain Detection**: Probes domain-level wildcard acceptance to prevent deliverability traps.
- **Disposable & Temporary Domain Isolation**: Live in-memory database filtering 100,000+ burner email providers (e.g., Mailinator, TempMail, GuerrillaMail).
- **Role Account Classification**: Flags departmental/functional aliases (`admin@`, `support@`, `sales@`, `info@`, `billing@`) to reduce spam complaint risks.
- **Full Inbox Detection**: Identifies over-quota storage mailboxes that bounce incoming mail.
- **Provider-Specific Normalization**: Automatic alias deduplication and canonicalization for Gmail, Outlook, iCloud, Fastmail, and Yahoo.
- **Zero-Waste Billing Protection**: Automatic 100% credit refund on any inconclusive or temporary `UNKNOWN` verification result.
