This customer data and insights can then be used to personalize marketing campaigns and offers for better customer engagement. 3. E-CRM also streamlines marketing processes like campaign management, targeting, creative development, and performance tracking to reduce costs and improve effectiveness. 4. By integrating E-CRM data and tools into their overall marketing strategy, companies can enhance customer relationships and generate more value over the long-term.
