Cold email marketing remains one of the most cost-effective ways to generate B2B leads in 2024. But what returns can businesses actually expect? We’ve analysed real data from our client campaigns to reveal the true ROI figures behind successful cold email strategies.
The Current State of Cold Email Marketing
Recent industry research shows that email marketing delivers an average ROI of £35 for every £1 spent (Data & Marketing Association, 2023). However, B2B cold email campaigns often perform differently from general email marketing, with unique challenges and opportunities.

Monitor Key Metrics
Track open rates (40%+), response rates (2–4%), meeting bookings (15–25%), and pipeline conversion.
Integrate with Other Channels
Cold email works best as part of a multi-channel strategy. Clients see 40% better results when combining email outreach, LinkedIn prospecting, cold calling follow-ups, and website visitor identification.
Long-term ROI Considerations
While immediate returns matter, consider the lifetime value of acquired customers. Our analysis shows that cold email clients have 23% higher retention, 15% larger deal sizes, and are 31% more likely to provide referrals.
The Bottom Line on Cold Email ROI
Real client data demonstrates that well-executed cold email campaigns consistently deliver strong ROI across industries. With average returns ranging from 400–800%, cold email remains one of the most effective B2B lead generation strategies.
Success depends on precise targeting, quality messaging, and systematic follow-up. When combined with other prospecting channels, cold email becomes even more powerful, creating a comprehensive approach to B2B lead generation that drives measurable growth.
