Send your cold email to a unique test address and get an AI-powered deliverability + quality score with detailed improvement suggestions. Watch the analysis happen in real-time.
Cold email success depends on two critical factors: getting delivered (avoiding spam) and getting opened (compelling copy). Our free Email Score tool analyzes both with AI-powered scoring and real-time feedback.
Send your cold email to a unique test address and watch our AI agent analyze it step-by-step. We score 6 key dimensions: situation recognition, value clarity, personalization quality, CTA effort, punchiness, and subject line effectiveness.
The magic is in the real-time timeline. Instead of boring forms, you'll see an AI agent working through the analysis: receiving your email, extracting content, running spam checks, scoring copy quality, and generating improvement suggestions.
Most email tools focus only on deliverability OR copy quality. We analyze both. Bad copy kills response rates even if you reach the inbox. Poor deliverability means great copy never gets seen. Our comprehensive scoring helps you optimize for both.
The scoring framework is based on Hans Dekker's cold email mastery principles: leading with situation recognition, clear value propositions with proof, genuine personalization over generic templates, and low-effort CTAs that encourage responses.
Beyond scoring, we provide actionable improvement suggestions and a complete rewrite showing best practices. Perfect for sales teams, agencies, and founders who want to improve their cold email performance without expensive consulting.
We generate a unique email address for your test. Send your cold email there exactly as you would to a real prospect.
