Understanding Email ROI and Engagement Metrics
Industry Intelligence Center · Updated: November 2025 · Reviewed by: SICCODE Research Team
Strong B2B marketers don’t just send emails—they measure everything. Knowing exactly how campaigns perform allows you to improve strategy, budget allocation, and customer acquisition cost. When campaigns are built on verified SIC and NAICS data, every metric becomes more accurate, providing real benchmarks that drive measurable growth. For industry-specific targeting, Email Lists by Industry help achieve the highest standards of deliverability and performance.
Why ROI Measurement Matters
Return on investment (ROI) reveals how effectively your campaign turns budget into revenue. In email marketing, it measures the value of every click and conversion. A clean, verified list dramatically raises ROI by improving deliverability and engagement—each of which compounds financial performance. For a detailed comparison of email data quality, see Why Verified Email Data Outperforms Subscription Databases.
How to Calculate Email ROI
The standard formula: (Revenue − Campaign Cost) ÷ Campaign Cost × 100 = ROI%.
Example: A $4,000 campaign that generates $14,000 in closed deals has an ROI of 250%. Verified SICCODE lists minimize waste, turning higher deliverability and conversion rates into lasting profit.
Core Engagement Metrics
- Delivery Rate: (Delivered ÷ Sent) × 100 — target 98% or higher.
- Open Rate: 18–30% average; over 35% for verified SIC-targeted sends.
- Click-Through Rate (CTR): 3–7% average; 2× higher with industry-specific offers.
- Bounce Rate: Keep below 2%.
- Unsubscribe Rate: Maintain under 0.5% for strong relevance.
Benchmarks for these metrics are detailed in Industries with the Highest B2B Email Engagement Rates, supporting continuous improvement across campaigns.
