Every message variant scored automatically. Get letter grades (A-F) before sending a single email. Catch deliverability issues early.
Subject Line (0-25): Length, clarity, spam words, personalization, mobile optimization
Preview Text (0-20): Extends subject, adds context, length, mobile truncation
Body Content (0-25): Value proposition, scannability, formatting, brand voice consistency
CTA Quality (0-20): Action verbs, specificity, placement, urgency, clarity
Deliverability (0-10): Spam words, link count, formatting issues, text/HTML ratio
Test personalized vs generic, question vs statement, curiosity vs clarity, emoji vs no emoji. Subject lines have the highest impact on open rates.
Test message length (short vs detailed), tone (formal vs casual), value prop emphasis, story-based vs direct, bullet points vs prose.
Test morning (8-10am) vs afternoon (2-4pm) vs evening (7-9pm). Optimal times vary by audience—test to discover what works.
Test button text ("Get Started" vs "Try Now"), placement (above fold vs bottom), design (button vs link), urgency level.
Test name in subject vs no name, dynamic content vs static, behavioral triggers vs generic, segmented messaging vs one-size-fits-all.
Test 3-email vs 5-email sequences, daily vs every-2-days cadence, aggressive follow-up vs gentle nurture.
The Analyst Agent enforces minimum thresholds for valid conclusions:
• Sample Size: 500+ per variant (statistical power)
• Collection Period: 48+ hours (time zone coverage)
• Confidence Threshold: 95% (statistical significance)
Experiments that don't meet thresholds continue running until they do. No premature winners declared.
