High-Throughput Multi-Layer Validation
RFC-compliant syntax validation to catch typos (e.g., user@@domain.com).
Verifies if the domain has valid mail servers configured to receive mail.
Directly connects to mail servers for existence check without sending mail.
Identifies domains that accept all emails to prevent false positives.
Supports massive CSV/Excel lists with automated column mapping and high-speed distribution.
Quick-check tool for verifying individual emails one by one with the same enterprise accuracy.
Custom logic (Specialists) for major providers that usually block standard verification tools. Bypass rate limits and sophisticated security patterns with ease.
Uses deep GetCredentialType API checks and sequential probes to verify business accounts accurately.
Handles Google's sophisticated rate-limiting and verification patterns across all workspaces.
Custom handshake logic specifically tuned for the Verizon Media/Yahoo technology stack.
Dedicated support for BT Internet, BigPond (Australia), TalkTalk, and Mail.ru.
Unlimited scaling via external "Satellite Nodes" that verify emails in parallel. Bypassing the speed limits of a single IP while ensuring maximum sender reputation safety.
Add unlimited nodes to verify emails in parallel, bypassing the speed limits of a single IP.
Distributes workload across multiple servers to prevent IP blacklisting.
If a node gets rate-limited, the system automatically retries on a different available node.
Monitor health, latency, IP reputation, and success rate from a central dashboard.
A zero-network local check that identifies known honey-pots before hitting servers.
Automatically filters domains known for aggressive blacklisting or DNS-level trapping.
Flags bot-generated emails (e.g. asdlkfj123@domain.com) indicating low-quality leads.
Integrated tool to check if your node IPs are listed on major RBLs (Real-time Blackhole Lists).
Integrated tool to verify if your server's ISP allows SMTP traffic on standard verification ports.
Encrypted verification paths ensuring maximum privacy for both you and the provider.
Beyond verification. Manage millions of data points with intelligent sorting, real-time analytics, and custom data workflows.
Results sorted into Valid, Invalid, Catch-all, Disposable, Role-based, and Syntax Error.
Track jobs with real-time progress bars, ETAs, and per-provider success statistics.
Download only the results you need (Valid, Catch-all) into CSV or Excel with one click.
Automatically merges duplicate emails within a job to save you time and node processing.
Full verification history with detailed SMTP logs for every single email ever checked.
You own the data. No third-party API ever has access to your sensitive leads.
