STEP 2 - Generate Your Email List

Step 3 - Sort Your Email List
Once you've accessed your list, you can choose to display member e-mail addresses only, the e-mail with first and last names using commas, or you can generate a simple list that displays the data line by line.
Step 4 - Copy Your Email List
Once you've selected the display format of your preference, you can highlight the text in the list and copy it by pressing the key combination CTRL+C on Windows, Command+C on a Mac. You can also use the right-click function on your mouse to copy list data if your computer mouse has that feature enabled.
You can then paste your data into a plain text file, a spreadsheet, or directly into a mail manager program of your choosing by pressing the key combination CTRL+V on PC, Command+V on Mac.
No matter what file format you choose, it's always a good idea to remember to save a copy of your data to your machine as well for future reference.
