Mobile advertising

Whether you want to contact your own customers or reach out to potential clients, you can use one of the mobile marketing options.

Most recipients pay more attention to advertising messages sent by SMS than to those communicated through other means. In addition, the service allows customers to respond instantly, such as making a purchase or order, sending a request for more information or contact. For this purpose, replies to received SMS, sending of payment SMS, links to websites and others are used. Combined with a well-defined target audience, mobile marketing becomes a highly effective way of marketing communication.

To reach existing customers, just provide a database of phone numbers and the text of the message you want to deliver.

To address potential customers, it is necessary to define their characteristics. Based on this, a target group of recipients will be created to receive your message. The most frequently used targeting parameters are age, gender, current location, residence, customer behavior on the Internet and related interests.
