Ready to turn your customers into die-hard fans? Let's go! 🚀
Why optimizing customer relations is crucial in 2025
The figures speak for themselves:
- 74% of customers consider customer service to be the primary loyalty factor (ahead of price or product!)
- 5x cheaper to retain an existing customer than to acquire a new one
- +An average 15% increase in revenues for companies that excel in customer relations
- 89% of customers leave a brand after a bad experience
Customer relations are no longer a "nice to have", they're a major competitive advantage.
And the good news? With the right tools like Klark, optimizing your customer relations has never been so accessible.
5 steps to optimizing customer relations
Step 1: Get to know your customers
You can't optimize a relationship if you don't know your customers.
What you need to know :
- Demographics: who they are (age, location, occupation)
- Buying behavior: what do they order? How often do they order?
- Interaction history: what have their past exchanges with you been?
- Friction points: where do they encounter problems?
- Contact preferences: email, chat, phone, social networks?
How do you collect this data?
- Well-configured CRM (Salesforce, Zendesk, Freshdesk, etc.)
- Post-purchase satisfaction questionnaires
- Analysis of support conversations
- Tracking behavior on your site/app
The mistake to avoid: Collecting data without using it. What's the point of having a full CRM if nobody uses it to personalize the experience?
At Klark, we automatically leverage your CRM data to personalize every customer interaction.
Step 2: Be available and responsive (really)
Your customers want answers now. Not tomorrow, not 48 hours from now. They want them now.
Expectations in 2025:
- 90% of customers expect an immediate response
- 64% of customers are ready to switch brands after just one bad experience
- 24/7 availability has become the norm, not the exception
How do you get there?
- Intelligent automation: AI chatbots for simple questions
- Self-service: FAQ, help center, video tutorials
- Multi-channel: be present where your customers are (email, chat, telephone, social networks)
- Proactive notifications: let them know before they ask ("Your package is on its way!")
Klark tip: With our automated customer support, your customers get instant answers, even at 3 a.m., without blowing your costs.
Step 3: Customize each interaction
Customers no longer want to be treated like numbers. They want to feel unique.
The difference between generic and customized :
❌ Generic: "Hello, how can I help you?"
✅ Personalized: "Hello Sophie! I see you ordered our new product X last week. How can I help you today?"
How to customize on a large scale?
- Use customer history: past purchases, preferences, previous interactions
- Segment your communications: new customers vs. loyal customers vs. VIPs
- Adapt the tone: formal for B2B, casual for B2C young people
- Intelligent recommendations: "You liked X, you'll love Y".
- Targeted offers: promotions based on purchasing behavior
The role of AI:Artificial intelligence enables personalization at the scale of thousands of customers without manual effort.
Step 4: Solve problems quickly (and well)
A customer problem solved quickly = a loyal customer. A problem that drags on = a lost customer.
The golden rules :
- First contact resolution: aim for 70% minimum
- Fast response time: ideally within 1 hour for urgent cases
- Genuine empathy: "I understand your frustration" (and mean it)
- Proactive follow-up: call back to make sure the problem has been solved
- Compensation when necessary: commercial gesture to turn a bad experience into a good one
How to improve your processes :
- Identify recurring problems and correct them at source
- Train your agents to solve, not just respond
- Empower your agents (authority for commercial gestures)
- Use AI to suggest solutions to agents(Klark Copilot)
Measuring for progress :
- FCR (First Contact Resolution): % of problems solved on first contact
- Average resolution time
- CSAT post-resolution: post-resolution satisfaction

Step 5: Create a company-wide customer culture
Customer relations are not just a matter for the customer service department. It's the business of the whole company.
How can we spread this culture?
- Top-down commitment: management must lead by example
- Customer KPIs for all: even dev or marketing have satisfaction-related objectives
- Share customer feedback: every month, share feedback (good and bad) with the whole team.
- Celebrate customer victories: highlight positive testimonials
- Continuous training: soft skills, empathy, problem solving
The benefits:
- Fewer silos between departments
- Customer-driven product decisions
- More consistent customer experience
- More committed and proud teams

Mistakes that destroy customer relationships
❌ Mistake #1: Not keeping your promises
You promise delivery in 48 hours and it arrives in 5 days? That's the end of it. The customer won't come back.
Solution: Under-promise, over-deliver. It's better to promise 3 days and deliver in 2 than the other way around.
❌ Mistake #2: Repeating the customer
"Can you give me your order number again? And your email? And what happened again?"
Unbearable. Your CRM must contain all the information you need, instantly accessible.
❌ Mistake #3: Answering without solving
"Thank you for your message, we've taken your request into account." And then... silence.
An answer without a solution = worse than silence.
❌ Mistake #4: Ignoring negative feedback
An unhappy customer who tells you = an opportunity. Ignore him and he'll tell 10 people on the networks.
Solution: Respond quickly, show empathy, propose a concrete solution.
❌ Mistake #5: Thinking price is everything
"If we lower our prices, we'll keep our customers."
False. 74% of customers prioritize customer service over price. A satisfied customer pays more without any problem.
