Hints for generating a text file for bulk upload
Spreadsheets and word processing programs may create lists with additional information that need to be removed or stripped out. A very simple way to create a text file of email addresses is to copy your list into a "text editor" In Ubuntu click Dash Home and search "text" or in Windows choose Notepad.
Text Editors don't have the capacity to include extra formatting so pasting information into those programs will remove some of the unwanted information. After pasting, if you have commas, quotes you must edit this information out. Search and replace commas and quotes with nothing to remove them. Email addresses must be on separate lines as well.
The following list shows a "clean" list of addresses.
