Provides a complete personalised email sequence design framework to help you build an efficient email marketing system.
📊 Email Marketing Market Status and Value
In 2026, despite the rise of social media and messaging apps, email remains the highest ROI digital marketing channel. According to Litmus data, the global email marketing market reached £17B, with average returns of £42 for every £1 spent. More importantly, email marketing is undergoing intelligent transformation: AI-driven personalisation brings 760% revenue increase, while automation workflows save 80% operational time while tripling conversion rates.
Key Data Insights:
- User preference: 72% of consumers prefer receiving brand communications via email
