Aavya Beauty was acquiring new customers profitably, then losing most of them after one order. Here's how email and WhatsApp lifecycle flows more than doubled repeat rate — until retention alone drove over a third of monthly revenue at near-zero CAC.

Retention & Lifecycle Marketing
Email + WhatsApp flow design, segmentation
Aavya Beauty's paid acquisition was working — new customers arrived profitably every month. The problem was what happened after checkout: a single generic "thanks for your order" email was the entire post-purchase experience. No replenishment reminders for consumable products, no cross-sell based on what someone actually bought, no WhatsApp presence despite it being where customers already messaged the brand with questions. Only 14% of customers ever placed a second order, so growth depended entirely on feeding fresh (and increasingly expensive) traffic into the top of the funnel every single month.
Segmented customers by product category, purchase frequency and consumable replenishment cycle before building a single flow.
Welcome series, post-purchase education, replenishment reminders timed to actual product usage, and a win-back flow for lapsed customers.
Moved key lifecycle touchpoints to WhatsApp, where open rates and reply rates ran far ahead of email alone.
Personalized cross-sell recommendations based on actual purchase history, not generic "customers also bought" blocks.
A dedicated flow and perks for the top repeat-purchase segment, protecting the brand's highest-value relationships.
Every flow tracked to attributed revenue and CAC-free contribution, reported alongside the paid acquisition numbers.
Replenishment timing was the single biggest lever. Reminders timed to when a consumable product actually ran out — not a generic 30-day interval — drove more repeat orders than every other flow combined.
More than doubled through lifecycle flows built around real product usage, not generic timers.
Up from a business that depended entirely on fresh paid traffic every month.
Retention revenue comes from customers already acquired — no additional ad spend required.
"We used to start every month from zero, chasing new customers to hit the same number. Now over a third of our revenue comes from people we already won — at basically no extra cost. It's changed how we plan the whole business."
Repeat-rate and revenue-share figures come from Shopify Analytics, comparing the engagement's flow-attributed revenue against the pre-engagement baseline. Timeframe and starting baseline stated above, as with every case study we publish.
