People prefer to acquire products and services from trusted brands and businesses with which they feel connected. An email marketing campaign is another and a more personal mean of communication to achieve that connection with your prospect or client. Also, it is an excellent tool to measure customer retention and loyalty by sending exclusive offers and discounts. In addition, it is super easy for your contacts to share the information received with others because the email campaigns integrate the company’s social networks with the purpose of increasing the audience. Another benefit of mass marketing by email is the reports obtained to measure the success of the campaign. Only lists of people who have chosen the option to receive messages from the company via email are used, and the option to remove their contact information from the list to avoid spam is included.
