Flaschenpost Recovers CHF 50K in Lost Revenue With Automated Cart Recovery Campaign

Industry: Grocery

Flaschenpost was founded in 2007 and started with around 2,000 wines, which were shipped from a student apartment at the time. Today, the company is Switzerland’s largest online wine retailer, offering over 30,000 wines. Its goal is to make buying wine as easy as possible. It offers a wide selection, attractive prices, fast delivery, and digital services that help all wine lovers find exactly the right wine.

Challenge

Flaschenpost.ch lost sales potential due to abandoned purchases in its web shop. Customers who were ready to buy added wines to their shopping carts but left the checkout before completing their purchases — a critical pain point for an ecommerce model that relies on convenience, inspiration, and repeat purchases.

  • Every abandoned shopping cart represented a clear intention to purchase. Without automated cart recovery mechanisms, this revenue potential remained untapped, even though the probability of conversion was well above average.
  • Manual outreach couldn’t scale = missed opportunities. With growing traffic and an expanding product range, manually identifying and addressing shopping cart abandoners was no longer feasible from an operational standpoint. Valuable purchasing impulses were lost without personalized reminders or targeted reactivation.
  • The key challenge was to identify highly qualified purchase intentions in real time and activate them automatically, personally, and across channels in order to sustainably increase conversion, customer lifetime value, and marketing efficiency.

Solution

Flaschenpost implemented an abandoned cart recovery flow powered by Loomi AI and pre-built cart recovery capabilities.

Key elements:

Real-Time Cart Triggers

The journey starts from a live cart_update event as soon as a shopper adds wines to their basket and leaves without purchasing.

Consent-First Targeting

Only customers with a valid email address and active marketing consent are eligible, ensuring compliance and focusing efforts on reachable, opted‑in contacts.

Smart Timing and Fatigue Control

A waiting period gives customers time to purchase on their own.

Additional checks exclude anyone who recently bought or already went through an abandoned cart flow, acting as a built‑in frequency cap.

Silent hours ensure messages don’t go out in the middle of the night, aligning with customer expectations in the Swiss market.

Loomi AI’s send time optimization capabilities help ensure emails land when each recipient is most likely to open and engage, based on their historical behavior.

Personalized Cart Reminders

Recovery emails highlight the exact wines left behind, with imagery and pricing pulled from the cart, plus a one‑click return to checkout so customers can easily complete their order.

How It Works

  1. Customer adds wines to cart

A cart_update event captures the selected bottles from the customer’s uncompleted shopping cart. 

  1. Loomi AI checks eligibility

The flow verifies email validity, marketing consent, and recent activity (purchases and earlier abandoned cart journeys). Only qualified customers continue.

  1. Loomi AI and business rules set the timing

A wait node delays outreach to avoid interrupting organic purchases.

Silent hours and per‑customer behavior patterns determine the best time to send the reminder.

  1. Personalized email is sent

The customer receives a brand‑aligned email showing the wines they left behind and a direct link back to their saved cart.

  1. Customer returns and completes purchase

A frictionless path back to checkout helps turn initial interest into a completed wine order, improving recovery of otherwise lost revenue.
