Sand-Mill Model
I am a Growth Specialist with a focus on Marketing Automation: I develop strategies to grow e-commerce businesses and SaaS brands by building automatic, relevant, and personalized communications with leads and customers via Email and WhatsApp. I use a data-driven approach centered on experimentation and optimization to work on the whole Customer Lifecycle. I apply the Sand-Mill Model, a framework I developed as an evolution of the Traditional Marketing Funnel to create effective Customer Journeys by leveraging Marketing Automation and Inbound Marketing. Originally conceived as an academic research project, I have since used it to support the growth of 50+ companies through consulting and strategic guidance. Starting with qualitative and quantitative analysis, I build conversion paths and diagnose retention issues between the first and subsequent purchases, resolving them by constructing a Rebuy Wheel, as it is defined in the Sand-Mill Model jargon. You can learn more about the Sand-Mill Model at www.sandmillmodel.com. In parallel with my consulting activities, I share my experience and knowledge with professionals and companies in specialized training sessions on the applications of the Sand-Mill Model in Marketing Automation. How can we collaborate? 📈 Consulting: My consulting focuses on an in-depth analysis of your company, products, and customers to identify growth opportunities through Marketing Automation. Specifically, I will help you: • Analyze your ideal customers’ buying journey • Identify friction points and opportunities in your current sales funnel • Build a comprehensive marketing strategy to manage the entire customer lifecycle, from lead generation to retention. I rely on data and experimentation to achieve tangible results and sustainable growth for your business. 👨🏼‍🏫 Training: I regularly conduct corporate training sessions, speak at events, and teach at the Universities of Modena, La Sapienza, Naples, and the 24Ore Business School. Through lectures, case studies, and workshops, I guide students and corporate teams in generating new growth ideas and connecting the dots to build a complete, automated, and scalable Sand-Mill. The topics I cover include: email marketing, Marketing Automation for e-commerce, growth strategies, inbound marketing, lead generation, segmentation and personalization, a scientific approach to KPI optimization, WhatsApp Marketing Automation, and the Sand-Mill Model. 📩 To collaborate with me, write to alvise@sandmillmodel.com
