What you will learn
- Explain CRM and its aims
- Assess potential retention and customer-value benefits
- Evaluate CRM costs and data responsibilities
CRM builds and manages customer relationships
Customer relationship marketing uses customer information and interactions to attract, retain and develop customer relationships. A business may use service records, feedback, preferences or purchase history to make communication and support more relevant.
The intended benefits can include repeat purchase, customer loyalty, feedback and lower costs of serving known customers. These are possible outcomes, not guaranteed effects; service quality and the relevance of the offer still matter.
Value must justify cost and protect trust
CRM can require software, staff time, data cleaning, training, customer support and secure information handling. Poor records can lead to irrelevant messages or bad decisions.
Customers may object to excessive contact or unexpected data use. Businesses should collect only appropriate information, follow applicable privacy rules, explain relevant choices and protect records. Measure retention and contribution alongside campaign and service costs.
Pause and explain
What is a useful way to assess whether a loyalty programme is worthwhile?
Worked example
A bookshop sends a reminder when a customer is due to collect a reserved title. Explain one CRM benefit and one cost or risk.
Show the worked solution
- The reminder uses a known customer interaction to make service more useful.
- Convenience may encourage repeat custom or reduce missed collections.
- Keep contact accurate, limited and handled securely.
Answer The reminder may make collection convenient and support repeat custom. The bookshop needs accurate records and staff or system time, and it should avoid using contact details beyond the customer's expectations or applicable permissions.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A café offers a digital stamp card. Explain one potential benefit and two measures it could monitor.
Give me a hint
Connect the offer to repeat behaviour and business value.
Compare my reasoning
- A reward may give customers a reason to return.
- Track repeat visits and average contribution per member.
- Compare reward, system and communication costs.
A stamp card may encourage repeat visits. The café could monitor visit frequency and contribution from participating customers, then compare these with reward and system costs; it should also check whether visits are genuinely additional.
Look for these in your work
- Mechanism is plausible
- Two relevant outcome measures are named
- Cost or additionality is considered
An online shop's CRM sends duplicate promotions and wrong names. Explain the likely relationship effect and a practical correction.
Give me a hint
Treat poor data quality as a customer experience problem.
Compare my reasoning
- Incorrect messages can reduce relevance and trust.
- Review consent, data quality and duplicate records.
- Test corrected communication and provide contact preferences.
Duplicate or inaccurate messages can frustrate customers and reduce trust. The shop should clean records, check how data are collected and used, honour contact preferences and monitor complaints and unsubscribes after correction.
Look for these in your work
- Customer effect is explained
- Data quality is addressed
- Customer control and follow-up are included
A hotel proposes expensive personal offers to every past guest. Evaluate what evidence should guide the decision.
Give me a hint
Compare relevance and incremental value with cost and customer expectations.
Compare my reasoning
- Estimate whether offers create additional bookings.
- Include software, staff, discount and data-handling costs.
- Check customer preferences and compare a small pilot with a suitable group.
The hotel should estimate incremental bookings and contribution after discounts, system and staff costs, and assess whether contact is welcome and appropriate. A limited pilot with clear preferences can test value before a wider programme.
Look for these in your work
- Incremental outcome is distinguished from existing demand
- Full costs and trust are considered
- Pilot is an evidence-based next step
Common mistakes
- Equating more customer messages with stronger relationships
- Assuming loyalty follows automatically from a database
- Ignoring data accuracy, privacy and security costs
