The rfm analysis is a wonderful technique to use to divide customers into segments based on three critical factors: Recency-how recently they interacted with the brand; Frequency-how often they engage with the brand, and Monetary-how much they spend. This segmenting allows you to send tailor-made and contextual emails to your customers, thereby enhancing the level of engagement with your offerings, resulting in sales growth. You can also opt for tools like Klaviyo and Omniconvert that can help you implement this model easily.
