email as a source data

 Hi you all.

I'm new to using SSIS. My project is to load csv file into an oracle database weekly using SSIS. 

The source file comes in an email weekly. My problem is how do I use the SSIS to get the data from an email and load it to the database? Do I need to write a script? Would somebody walk me through this? Sample script will help me a lot. 

Thanks in advance. 

* I created an SSIS project to do the same though I manually transfer the source out of email and save in the a folder.
