Ecommerce profitability is driven by customer lifetime value. A customer who buys once and never returns costs you acquisition cost with no return. A customer who buys quarterly for two years generates 8x the revenue at near-zero marginal cost. The difference between these two outcomes is almost entirely a function of your post-purchase communication: review requests, related product offers, reorder reminders, and win-back campaigns.
Abandoned cart recovery is the other major recoverable revenue leak. Industry data consistently shows that 70%+ of ecommerce carts are abandoned. A 3-message recovery sequence — sent at 1 hour, 24 hours, and 48 hours — recovers 10-15% of abandoned carts at near-zero cost. For a store doing $50,000/month in revenue, this sequence alone can add $5,000-$10,000 per month.
