R10BatchMail is a simple to use Bulk Email Sending program for Macintosh OSX. R10BatchMail is useful for sending a newletter, informing of change of address, marketing or any one of a thousand other reasons for contacting your customers, prospects or suppliers. With R10BatchMail there is no need to clutter up your Address Book with prospects in order to contact them via email. Data is imported into R10BatchMail from an industry standard TAB Delimited file. A TAB Delimited file can be created from almost any application that holds data, and is the default format for 'bought in' lists. R10BatchMail records what was send and who to and allows you to export this history to Excel, a TAB Delimited File or Comma Separated File. From this file you can update your corporate database if necessary. R10BatchMail was designed primarily to be easy and quick to use, whilst still providing the essential functionality required.
