Paste your email. Simulate it against 16 real decision-maker personas across any industry. Get a verdict, a score breakdown, and an AI-rewritten version — in seconds.
CEO, CFO, CTO, Founder, VP Sales, VP Marketing, Head of Product, Procurement, Operations, Legal, HR, Finance, and more — each with distinct priorities, tolerances, and reply patterns.
Every email is scored across Open Likelihood, Relevance, Credibility, Friction, Motivation, and Actionability — with plain-English explanations of what's dragging your score down.
