Stop paying for
pattern guessing.
Hunter relies on finding common formats (like "first.last@company.com") and assuming your target matches. In 2026, guessing ruins domain reputation. Mailvah utilizes our proprietary V4.5 Cluster to execute bare-metal SMTP handshakes for absolute cryptographic certainty.
Deterministic Fact vs. Probability
Hunter.io built an incredible platform for the 2018 era of outbound. They scrape the web, find that 80% of employees at Microsoft use "first.last@microsoft.com", and when you search for the CEO, they return that pattern with a "Confidence Score."
Confidence scores are not facts. If a CEO uses a custom format (e.g., "initials@"), Hunter's guess will bounce, permanently damaging your domain's sending health. Mailvah's V4.5 Cluster never guesses. We verify.
V4.5 Heuristic Shield Bypass
When Hunter encounters an Enterprise "Catch-All" firewall, they mark the lead as "Risky" and give up. Mailvah fires a sequential 3-burst ghost ping of impossible alphanumeric emails to map the firewall rules, allowing us to extract the deterministic truth.

Upgrade your infrastructure.
Export your "Risky" lists from Hunter, drop them into the Mailvah Bulk Engine, and watch the V3.2 protocol verify the un-verifiable.
