How Le Bon Marché (LVMH) Scaled Personalized Customer Care and Saved 3-4 Minutes While Responding Using AI

Le Bon Marché Rive Gauche & La Grande Épicerie de Paris  

Le Bon Marché Rive Gauche and La Grande Épicerie de Paris are iconic Parisian department stores founded in the 19th century and widely regarded as pioneers of modern retail. Steeped in heritage yet driven by creativity and excellence, they deliver a singular customer experience where tradition meets innovation.

Customer satisfaction is a strategic priority, supported by a strong culture of listening, empathy, precision, and responsiveness. To further elevate these standards, the Customer Service team leverages advanced artificial intelligence (AI) solutions across key touchpoints—including social media, email, and voice-of-customer analysis—enabling faster response times, deeper insight into customer needs, and more consistent service quality at scale. This AI-powered approach supports a 20-person team recognized as a benchmark in premium, highly personalized, and deeply human customer relations, enhancing their ability to deliver elegance, reactivity, and continuous innovation.

Challenge

Customer service advisors were handling a high volume of messages across multiple digital channels, including social platforms, email, live chat, and phone support. Teams were required to respond within an average processing time, which caused advisors to prioritize urgent inquiries and complaints over engagement with positive customer reviews.

As a result, many 4-and-5-star reviews—often paired with kind words or heart emojis—were left unanswered due to time constraints, missing a critical engagement opportunity.

Another key difficulty was maintaining fast response times while preserving brand voice and internal communication standards, including:

  • Warm, personalized phrasing
  • House-style (Maison) language conventions and signature expressions
  • Context-appropriate emojis enhancing emotional connection
  • Careful nuance depending on the customer’s personality and request

Even though templates were available, every interaction required manual rewriting, because no single template covers every context. This meant that speed and personalization were often in conflict.

⭐⭐⭐⭐⭐
“Before AI, we didn’t always have the time to answer every positive review, even though we really cared about maintaining a personal and warm tone.”
— François Castetz, Head of Customer Care, Le Bon Marché

“The AI assistant makes us faster without compromising what makes us human: our tone, our warmth, our relationship with the client.”
— Customer Service Advisor

Solution

With Alcmeon’s AI assistant, advisors now generate structured draft replies instantly for every incoming social media inquiry or complaint, with all the essential elements already matching brand style requirements—including tone and emojis.

The workflow became:

  1. Click “AI assistant” for the incoming message
  2. Receive a complete structured reply draft in the tone and style of the brand and personalised according to customer message
  3. Review, refine, and edit, if required, before sending it

This dramatically reduces manual drafting time, while ensuring message structure, tone coherence, and brand response style consistent across the teams.

“AI proposes cleaner, more elegant and sometimes unexpected phrasing. It expands our range of expression without breaking our codes(brand guidelines).”
“It helps us write replies without having to think about paragraph structure. It saves us time and lets us focus on the relationship.”
— Customer Service Advisor

Result

Based on team observations, internal testing, and advisor feedback:

  • ~2 minutes saved per message on average
  • 3–4 minutes or more saved on complex complaint responses
  • Social response times, already strong, became even shorter
  • Every Google review now receives a reply—including 4–5-star positive reviews
  • This contributes to:
    • Higher online visibility & SEO improvement
    • Stronger client loyalty & engagement
    • Perfect tone consistency across teams
    • More creative and refined messaging variations from AI drafts
  • Internal satisfaction survey scores:
    • Average rating: 4.3 / 5
    • All respondents rated 4 or 5 / 5

Visibility, personalization, harmony, and response speed are now fully combined priorities—not competing ones.

“AI is an ally that helps us respond quickly, accurately and concisely.”
— Customer Service Advisor

Why this matters

By replying to all customer feedback instead of only critical cases, the brand now benefits from:

  • Stronger emotional reciprocity with happy clients 😊💬
  • Improved organic search ranking and SEO through consistent review replies
  • Elevated perceived service responsiveness, which directly influences customer satisfaction even without traditional CSAT surveys
  • A more empowered and comfortable advisor experience, reducing repetitive mental load


“We love customer support, but it’s demanding. AI was perceived as real support, not a constraint. Today, we couldn’t do without it.”
— François Castetz, Head of Customer Care, Le Bon Marché
