With so many emerging marketing platforms, is email marketing worth the hype? Does it generate good returns on investments? Or can we engage users with just emails? I would say yes to all these questions.


Look at these statistics: DMA report 2021 says that 72% of marketers prefer emails to engage with their customers. Moreover, the ROI for email has increased year on year from 40.12 USD (£35.41) to 43.45 USD (£38.33). These numbers show that email marketing is not one of the most prevalent and beneficial forms of marketing, and you leverage it to achieve your business objectives.

So, to help you, we created this guide of all email marketing statistics, which you can use to understand the importance of email marketing and develop your strategy.
