Mobile Marketing Pro, as it's name states, allows to create mobile marketing campaigns through delivery and reception of SMS text messages with keywords (also known as two way SMS). Also you can create SMS information services with an automated subscription and deletion system, that can be used to send news letters or other type of information. Using the personalization system it's easy to create identifiers that can be used in discount coupons, invitations or prizes and send them in SMS text messages. SMS Background Music interacts with Microsoft Windows Media Player and can import playlists that you have defined there. It generates codes for each song that your customers can use to request them sending SMS text messages. It also implements an smart ranking system to determine which song goes first and lets you define other parameters, that, for example, avoid to play twice the same song. From the marketing view point, SMS Background Music relates each song with customers who request them so you can identify their music preferences easily. New in version 2.5 are events autosend, that let's you send brithday greetings automatically, and SMS routing, that allows to send outgoing messages through a specific cellphone based on destination number or cell phone company. Mobile Marketing Pro has it's own cell phone server that allows 64 cell phones simultaneously sending and receiving SMS text messages. It runs on Windows 2000 Pro, Windows 2000 Server, Windows XP Pro, Windows 2003 Server and Windows Vista.
