Step 1: Install Lavender and Connect Your Inbox

Go to lavender.ai and install the browser extension for Gmail or Outlook. The setup takes about two minutes. Once installed, you’ll see the Lavender sidebar appear whenever you compose a new email. Connect your LinkedIn account to enable personalization features — Lavender will use this to pull prospect data automatically.

Step 2: Start Writing Your Cold Email

Open a new email and begin typing. As you write, Lavender’s AI analyzes your email in real time and assigns a score from 0 to 100. The score updates with every keystroke. You’ll see a breakdown of key factors: subject line effectiveness, personalization level, tone, readability, and length. Red indicators show what’s hurting your chances, while green indicators show what’s working.

Step 3: Improve Your Subject Line

Subject lines are the gatekeepers of email success. Lavender analyzes your subject line for length (6-10 words is ideal), curiosity triggers, spam keywords, and mobile readability. If your subject line says “Quick Question,” Lavender will flag it as overused and suggest alternatives. Try something specific and relevant to the prospect, like “Noticed your team is expanding into EMEA.”

Step 4: Add Personalization

Click the Lavender sidebar to see personalized suggestions for your prospect. If you’ve entered their email, Lavender pulls their LinkedIn profile, recent company news, and social activity. Use these insights to craft a personalized opener — not “I came across your company” but “Congrats on the Series B — I noticed you’re hiring for 3 AE roles in EMEA.” Lavender’s personalization coach will tell you if your opener feels generic or genuine.

Step 5: Optimize the Body and CTA

Lavender checks your email body for common mistakes: too long, too formal, too many questions, no clear CTA, or self-focused language (“I” instead of “you”). Follow the suggestions to trim your email to under 125 words, replace “I’d love to” with a specific ask, and ensure your CTA is low-friction — “Open to a 15-minute chat next week?” instead of “I’d love to schedule a demo.”

Step 6: Review Your Final Score and Send

Before hitting send, check your final score. Lavender research shows that emails scoring 70+ get significantly more replies than those below 50. If your score is below 70, address the remaining red flags. Once you’re in the green, send with confidence. Lavender tracks your send data and correlates it with replies, so you can see the real-world impact of your improved emails over time.

Pro Tips for Better Results

• Aim for emails under 125 words — shorter emails consistently get more replies
• Use one CTA per email — multiple asks confuse prospects and reduce reply rates
• Personalize the first line, not the whole email — forced personalization feels creepy
• Send emails on Tuesday through Thursday between 8-10 AM in the prospect’s timezone

With Lavender, every email you send is coached by data from millions of sales emails. Stop guessing what works and start writing emails that get replies.
