The Summercall philosophy is that the customer is at the heart of any successful organisation and our starting point for any project is to interrogate the customer data to fully understand the different purchasing behaviours and patterns across the base.


This approach to marketing draws on data mining, analysis and segmentation techniques and applies the resulting insight to define a client's customer acquisition, retention or CRM strategy.

Typical projects include writing and delivering CRM strategy, customised segmentation, customer contact strategy, customer journey analysis, GDPR marketing readiness and building and managing customer databases.

Recent examples have included:

> Project managing a major GDPR marketing readiness programme for a leading UK Life company

> In depth data analysis and CRM strategy for a 5 star resort hotel

> End to End Global Campaign Process design for major tourism organisation
