Mobile marketing is multi-channel online marketing technique focused at reaching a specific audience on their smartphones, tablets, or any other related devices through websites, E mail, SMS and MMS, social media or mobile applications. Mobile marketing can provide customers with time and location sensitive, personalized information that promotes goods, services and ideas. In a more theoretical manner, academic Andreas Kaplan defines mobile marketing as "any marketing activity conducted through a ubiquitous network to which consumers are constantly connected using a personal mobile device".
