Ezi Car Rental operates a successful car rental business and is expanding its NZ brand and associated marketing activity. All online reservations and bookings are entered into the existing Booking system, Ezi Car Rental would like to expand its marketing content and build its brand. However, lacking a CRM system, Ezi Car Rental has no way to accurately segment their customer data in detail as the existing booking system does not allow effective segmentation with the level of granularity required. As a consequence, the marketing messages that are generated are not as effective as they could be as they are not targeted at the correct customers, and this is an area that could be significantly improved.
