Lavender

Lavender is the AI email coaching layer that lives on top of Gmail and Outlook and scores every cold and prospecting email before you send it. Where Instantly and Smartlead optimize sending infrastructure and Apollo optimizes contact data, Lavender optimizes the actual copy of each email — giving you a 0-100 score, calling out spammy phrases, suggesting personalization angles based on the prospect's LinkedIn, and rewriting weak openers as you type. Pricing starts free (limited daily usage), $29/month Starter (1 user, individual coaching), $49/month Team (up to 10 users with team coaching and analytics), and Enterprise (custom).

The killer features are the real-time email scoring, the LinkedIn personalization assistant (one-click pulls relevant context from a prospect's profile into your draft), and the team-level analytics that show which reps' emails are scoring highest and replying most. The honest assessment in 2026: the email scoring is a genuinely useful guardrail for SDRs and founders writing manual cold email, but it's less valuable for fully automated cold email at scale (where Instantly + Clay handle most of the personalization). For SDRs writing manual prospecting emails, founders running their own outbound, and small sales teams that haven't automated, Lavender measurably improves reply rates — typical lift is 2-3x according to public case studies.
