Lavender

Lavender is an AI email coaching tool that scores your sales emails in real-time as you write them. It analyzes subject lines, personalization quality, reading level, email length, and mobile optimization — giving you a score out of 100 with specific suggestions to improve. It pulls LinkedIn and news data about the prospect to suggest personalization angles. The Chrome extension works inside Gmail, Outreach, and Salesloft. Free tier includes limited scores per month.

Perfect for SDRs learning the craft of cold email, AEs who write their own outbound, and sales managers who want visibility into email quality before it goes out. The real-time coaching loop accelerates learning — instead of waiting to see low reply rates, you fix email problems before sending. Teams report measurable improvements in reply rates within weeks of consistent use.

Where it's limited: it coaches individual emails, not entire sequence strategy, and the free tier is too restricted for daily SDR use (paid starts at $29/month). Also, it's a coach, not a magic fix — still requires good research and genuine personalization. If you're sending 100 emails/day with minimal personalization, Lavender won't save you. But for thoughtful outbound reps, it's a genuine performance multiplier.
