Opening an email is great—it improves your brand awareness and customer communication, which indirectly could lead to more sales. But it doesn’t bring you any profit per se. Let’s find out what is the average ROI for email marketing. 

2. Email marketing ROI: statistics

3. Email marketing revenue statistics

Email marketing revenue worldwide is predicted to grow from $7.5 billion in 2020 to $14 billion in 2025.

Social media marketing scores second highest at 19% effectiveness. However, consider that about 20% more Millennials prefer to receive updates and promotions from a company via email than social media.

But keep the majority of your communication on email.
