Lavender is the AI email intelligence tool that coaches sales reps to write better cold emails by scoring messages in real time and providing specific, data-backed suggestions for improving reply rates. Its coaching system is trained on millions of sales emails correlated with response outcomes, identifying the exact factors — email length, personalization depth, subject line clarity, and call-to-action specificity — that statistically separate responded emails from ignored ones. SDRs and AEs at B2B sales teams use Lavender to continuously improve their email writing, with measurable improvements in reply rates as the AI coaching compounds over time.
