What is Cold Email Effectiveness Score?
A cold email score evaluates your outreach sequence across subject line appeal, personalization depth, value proposition, and call-to-action clarity.
The Formula
Score = (Points Earned ÷ Maximum Points) × 100
Worked Example
A cold email campaign: 32% open rate, 4.5% reply rate, 1.2% meeting rate across 500 sends.
- Open rate: 32/40 target = 80/100
- Reply rate: 4.5/5.0 target = 90/100
- Meeting rate: 1.2/2.0 target = 60/100
- Overall = (80 + 90 + 60) ÷ 300 × 100 = 77%
📌 The campaign scores 77%, strong opens and replies but the CTA needs work to convert more replies into meetings.
Why This Matters
Pipeline generation
Cold email generates 2-5x ROI when done well. It remains the most scalable outbound channel for B2B.
Cost efficiency
At $0.10-0.50 per email, cold outreach costs 80% less than paid advertising per qualified lead.
Feedback loop
Reply and open rates provide fast feedback on messaging effectiveness, enabling rapid iteration.
Common Mistakes
❌ No personalization
Generic emails get 2% reply rates. Personalized emails referencing specific company details get 5-8%.
❌ Too long
Cold emails over 150 words see 50% fewer replies. Get to the value proposition in 2-3 sentences.
❌ Weak subject lines
The subject line determines open rate. Questions and curiosity gaps outperform announcements by 20-30%.
