Email continues to be one of the most effective ways to connect with potential customers in APAC. For both established EDM marketing agencies and growing startups, email marketing lead generation services play a vital role in B2B strategies, particularly in dynamic markets like Singapore.
With 77% of B2B marketers reporting email as their top content distribution channel and an ROI of $42 for every $1 spent, understanding and optimising email performance proves to be essential.
This email marketing guide walks you through everything from program setup to measuring success using email marketing analytics. You’ll learn how to define your goals, track meaningful KPIs, and turn raw data into smarter decisions.
What Are Email Marketing Metrics?
Email marketing metrics are performance indicators that help you evaluate the effectiveness of your programs. Whether you’re running a cold email lead generation push or nurturing your base with personalized email sequences, knowing what to measure can determine whether your email marketing program sinks or scales.
Email marketing insights for Singapore and APAC
- In Singapore, the average open rate for email programs is around 21.85% slightly above global benchmarks.
- APAC has a higher CTR (4.71%) than the USA and EMEA.
These metrics provide a roadmap to optimize engagement, ensure deliverability, and improve ROI. But tracking data is only half the story. You need the right foundation before analytics can truly work.
Prerequisites for Measuring Email Marketing Success

Before you can fully leverage email marketing analytics, you must first establish a solid strategic foundation. In B2B marketing, jumping straight into metrics without clear planning, clean data, or the right tech stack often results in disconnected efforts and misleading insights.
Whether you’re a lean startup exploring email marketing lead generation services or a seasoned Electronic Direct Mail (EDM) marketing agency expanding across the region, success depends on having the right prerequisites in place. Without them, even advanced reporting tools will offer limited value.
