The greatest advantage is that you can create an excel file with the phone number name and other five customizable fields and then this can be imported to the software to send customized SMS to each person. Before importing save the excel file as a csv file using save as option. The software supports Long SMS, Flash SMS, SMS Mail Merge etc. for Nokia, Sony Ericsson or Motorola mobile phones. Free version and paid versions are available but the free version is also powerful but with the small advertisement about SMScaster in the sms text. So many message sending options and bundled features are available in the software which is worth trying.
