Customer engagement and retention explained

What is customer engagement?

Customer engagement is the ongoing interaction between customers and brands across multiple touchpoints throughout the customer journey, from the initial discovery and conversion to onboarding and customer retention. Effective customer engagement combines behavioral insights, timely communication, and personalized experiences delivered across mobile and digital channels to meet customers right where they are. 

What is customer retention?

Customer retention measures whether a customer will continue their relationship with you or switch to a competitor. Retention is tracked through metrics such as churn rate, customer lifetime value, and repeat purchase rates to guide your customer engagement strategy. The outcome of strong customer retention is sustained customer loyalty, higher lifetime value, and more predictable revenue over time. 

Customer engagement vs. customer retention

While customer engagement and customer retention both involve winning your customer’s attention (and hopefully their loyalty), they differ in their approach. Customer engagement focuses on how actively your customers engage with your brand and is essential throughout the entire customer lifecycle. Customer retention, on the other hand, focuses on ways to keep your customers coming back. It is the most cost-effective way to build customer loyalty, resulting in 25-95% profit growth, compared to acquiring a new customer. 

Put another way, engagement opens the door for customers and guides them to where they convert; retention is keeping the door open and is the measurable result of how well your customer engagement strategy is working. Let’s break down the key differences between customer engagement and customer retention even further:

Types of customer engagement and retention strategies

Customer engagement and retention strategies help businesses understand what customers are looking for over time. But each strategy provides a different context. Here are some of the most common types of customer engagement and retention strategies used across mobile and digital experiences. 

• Mobile-First Engagement: Prioritize fast, intuitive experiences for the apps, social media platforms, and websites customers visit most often to create a user-friendly mobile experience.
• Behavioral Engagement: Use real-time customer actions and preferences to create messaging that reflects what customers do, not assumptions. 
• Lifecycle Engagement: Support customers from onboarding through renewal by delivering timely, relevant messaging that keeps them engaged throughout their journey.
• Cross-Channel Engagement: Coordinate messaging across multiple channels to create a cohesive customer experience, not a siloed one. 
• Personalized Engagement: Tailor messaging and experiences to individual customer preferences and behavior to create value. 
• Community Engagement: Encourage customers to participate, share feedback, and connect with others through user-generated content and shared experiences. 
• Retention-Focused Engagement: Keep customers coming back through loyalty programs, re-engagement campaigns, and ongoing, personalized communication. 

Why customer engagement and retention matter

Customer engagement and retention are essential to driving successful business outcomes. Engaged customers are very familiar with your brand and are more likely to take a desired action. Retained customers act as advocates for your brand and cost less to acquire. Without customer engagement and retention efforts, you risk profit and customer loyalty. 

Key customer engagement metrics

Customer engagement and retention involve many moving parts, but the key is to keep track to ensure that your efforts are working. Here are the most common customer engagement metrics to track: 

• Active Users: Tracks daily, weekly, and monthly active users to understand how frequently customers interact with your product or service.
• Engagement Rate by Channel: Measures the total percentage of interaction across email, mobile, and social.
• Customer Retention Rate: Calculates the percentage of people who continue to do business with you.
• Customer Lifetime Value (CLV): Estimates the total revenue a customer brings over time.
• Churn Rate and Prediction: Reveals the percentage of customers who stopped using your product or services and anticipates this through analytics.
• Customer Retention Cost (CRC): Measures the total investment required to keep customers engaged and coming back.
• Repeat Purchase Rate: Tracks the percentage of customers who make multiple purchases to understand their preferences.
• Net Promoter Score (NPS): Measures the likelihood of customers recommending your business to others.
• Time to Value (TTV): Assesses the time at which a customer starts using your product or service after a purchase.

Common customer engagement and retention challenges

Customer engagement and retention can feel complex, but not with the right strategies and tools in place. Here are some of the most common customer engagement and retention challenges brands encounter: 

• Fragmented customer data: When data is spread across multiple platforms rather than a centralized location, you struggle to see the whole picture. Unified data allows you to capture a single view to drive more relevant engagement. 
• Disconnected cross-channel messaging: Different messages across channels confuse customers. Coordinated messaging across email, SMS, push notifications, and web makes sure the customer journey doesn’t become disjointed. 
• Predicting customer churn: Spotting when a customer leaves isn’t always obvious. Analytics allow you to track when a customer might churn and act accordingly to prevent it.

How to build a strong customer engagement and retention strategy

A strong customer engagement and retention strategy requires constant iteration until customers respond as you want them to. Let’s take a look at what you need to not only win over customers but keep them as well: 

1. Start with clean, unified customer data

Clean and consolidate scattered data across mobile apps, websites, CRM platforms, and messaging channels into a single, unified profile to keep customer information in one place. Remove any identifiers to protect your customers’ data, improve accuracy, and create a foundation for your customer engagement strategy. 

2. Define clear engagement and retention goals (with measurable KPIs)

Always have a clear goal in mind before rolling out your customer engagement strategy to determine what metrics to measure. For example, if your goal is to reduce churn by 10%, you should track churn rate, engagement rate, time-to-value, and customer retention rate to understand why customers are leaving and where you can refine your strategy. 

3. Segment by behavior and lifecycle stage

Every customer is at a different stage of the customer journey. Some are ready to buy, while others are just discovering who you are for the first time. Segment your customer engagement strategy by their user history and behavior to understand where they are and where they want to go.

4. Map the complete customer journey across mobile and digital channels

Learn how users move from one channel to another to uncover any friction points or opportunities to improve their journey across each touchpoint. Once you’ve figured these out, map the customer journey to ensure a consistent experience. 

5. Build cross-channel orchestration capabilities 

Coordinate engagement across channels rather than using them separately. Cross-channel orchestration ensures that messaging is consistent with customer actions across channels, creating a more cohesive experience that builds trust. 

6. Implement AI-powered predictive retention models

Leverage AI and predictive analytics tools to identify when customers are disengaged. For example, if a customer is spending less time in your mobile app, predictive analytics can alert you before they leave, enabling you to create automotive messaging with personalized offers.

7. Create lifecycle-specific engagement programs 

Customers have different needs at different stages — plan by designing what they need across each stage to avoid overcommunication and friction. For example, create how-to videos and guides to quickly inform new customers about using your product and services during onboarding. 

8. Evaluate and invest in the right technology

Technology makes or breaks your customer engagement. Look for platforms that support the following: 

• No-code journey builders: Enable teams to design customer journeys without a developer background. 
• Intelligent journey orchestration: Automate customer journeys in real time based on behavior and engagement. 
• Comprehensive analytics: Measure engagement and performance rates across channels.
• Predictive analytics: Know when a customer is disengaged and use analytic insights to retarget your messaging. 
• Mobile-first architecture: Design mobile-first experiences at each touchpoint to deliver a connected customer journey. 

9. Establish continuous testing and optimization

Once you’ve implemented your customer engagement and retention strategy, don’t stop there. Continue testing and optimizing by timing your messaging and channels and by understanding what resonates with your customers. 

10. Align cross-functional teams around customer outcomes 

Keep your internal teams on the same page with customer outcomes to ensure that experiences are consistent, coordinated, and focused on long-term value rather than isolated metrics.
