Tuski

Tuski is AI-powered lead intelligence that finds better leads and tells you who's safe to reach.

Tuski pairs AI-assisted company research with real email delivery evidence to help revenue teams build cleaner, higher-quality outreach lists. It evaluates every address against concrete signals, runs controlled delivery probes, and returns a 0–100 quality score plus classified verdicts. It's built for operational revenue and growth teams who need to protect sender reputation and reduce bounce rates before a send.

Key features

• AI-assisted company research with firmographics, ICP evidence, source URLs and confidence signals
• 0–100 Tuski Quality Score combining MX/provider detection, address patterns, disposable-domain and gateway signals, and domain-health context
• Real delivery evidence from controlled probes, classified into outcomes like valid, invalid, full, blocked, catch-all and role
• CSV in / scored CSV out, with real-time job progress plus API and MCP automation

Ideal use case

Ideal for growth, lifecycle and SDR teams that run lists through validation before every campaign to cut bounce rates and safeguard deliverability.

Why use Tuski

Tuski charges only for addresses it actually checks with a probe — no-MX, burner and unreachable domains are free — and credits never expire. Every row carries an actionable quality score, and the product connects over MCP so you can run validations directly from AI assistants.

FAQ

What exactly do I pay for? One credit is spent per address Tuski checks with a controlled probe. Addresses it can't send to — no-MX/dead domains, burners and unreachable addresses — are free, and credits never expire.

How accurate are the results? Tuski sends controlled probe messages and classifies observed delivery-status notifications, so results reflect real delivery evidence when returned. The quality score is a relative signal, not a delivery guarantee.

Can I run Tuski from my AI assistant? Yes. Connect over MCP with your API key to launch checks, watch statuses and pull scored results from Claude Desktop, Claude Code or any MCP client.

TL;DR

Tuski is an AI-powered lead intelligence and email validation tool that scores deliverability on a 0–100 scale and backs verdicts with real delivery evidence. It helps revenue teams clean lists, protect sender reputation, and automate checks via API and MCP, while never charging for unreachable addresses.
