How to calculate customer lifetime value (email)
Why customer lifetime value (email) matters for Klaviyo users
Campaign-level revenue attribution shows what each send generated, but lifetime value reveals the cumulative impact of your entire email programme on customer relationships. Customers who engage with your Klaviyo emails may purchase more frequently, spend more per order, and remain customers longer.
Mapping email LTV into your metric tree connects your retention marketing programme to the highest-level business outcome. This justifies investment in email programme quality, personalisation, and automation by demonstrating long-term financial returns.
