What is the role of email marketing in today’s digital marketing landscape? Let’s take a look at the following key data points.

📧 **Open Rate**

According to Mailantpro, the global average email open rate climbed to 38.7% in 2025, an increase of 12 percentage points compared to 2022. This improvement is attributed to technologies such as AI-powered dynamic subject line generation systems and spatiotemporal intelligence algorithms. Even PlusVibe’s 2024 statistics showed that the average email open rate across industries was around 19.66%, while EngageLab’s 2025 report indicated an average open rate ranging between 17% and 28%.

📧**Conversion Rate**

In 2025, the median email marketing conversion rate reached 5.3%. For e-commerce, a conversion rate exceeding 2% is considered excellent, while the industry average for welcome emails is as high as 3%. Mailantpro’s report also highlighted that embedded smart shopping carts increased the share of direct purchases via email to 61%. Additionally, emotion recognition technology applied to CTA button design boosted conversion rates for financial emails by 39%.

These figures demonstrate that email marketing is not just about “sending emails” but rather about achieving tangible business growth through refined strategies and technological empowerment.

📧**Return on Investment (ROI)**

According to Mailantpro’s latest 2025 report, the average global email marketing ROI reached an astonishing 42:1, setting a ten-year high. This means that for every dollar invested in email marketing, you can expect a return of $42. Shopify’s 2024 data further supports this: for every dollar spent (approximately 7 RMB) on email marketing campaigns, it generated $42 in revenue (about 295 RMB), resulting in an ROI of 4,200%.

These numbers are enough to catch any marketer’s attention. In an era of rising customer acquisition costs, email marketing undoubtedly represents an underexplored “blue ocean.”
