Normalmente este tipo de servicios se utilizan para no dar nuestra propia dirección. Por ejemplo puede venir bien cuando una web te pide que introduzcas tu correo para acceder a una parte que no todo el mundo tiene acceso (con la intención de luego mandarte información que posiblemente no te interese). De esta manera no comprometerás tu cuenta y nunca te llegarán esos correos.
An omni-channel approach not only benefits consumers but also benefits business bottom line: Research suggests that customers spend more than double when purchasing through an omni-channel retailer as opposed to a single-channel retailer, and are often more loyal. This could be due to the ease of purchase and the wider availability of products.
In the 2000s, with increasing numbers of Internet users and the birth of iPhone, customers began searching products and making decisions about their needs online first, instead of consulting a salesperson, which created a new problem for the marketing department of a company. In addition, a survey in 2000 in the United Kingdom found that most retailers had not registered their own domain address. These problems encouraged marketers to find new ways to integrate digital technology into market development.
