Importing Data from Mail
The Apple Mail App can be used to transfer files into DataAnalysis.
One the right (top) is an email with an attachment (sample data.txt). Text files (.txt), comma separated value files (.csv) and DataAnalysis (.daes) can be opened. For information about file formats see (DataAnalysis File Format)
After Press and hold on the icon corresponding to the attaching, the iOS Action Sheet is exposed (see right bottom)
Press the DataAnalysis icon to have the program open the mail attachment. You may have to slide the available icons to the right to find the DataAnalysis Icon.
If the DataAnalysis Icon does not appear press on the More button 
and you will be able to find the DataAnalysis icon.
