You can try quering the file; assuming that UI is WinForms you can put something like this:

using System.IO;
using System.Linq;

...

var itemsToAdd = File
  .ReadLines(@"c:\ItemsToCreate.txt")
  .Skip(1)                            // Skip Caption   
  .Select(line => line.Split(         // Split each line 
        new char[] { ' ', '\t' },     // .. by tabulations and spaces
        StringSplitOptions.RemoveEmptyEntries) // .. while dropping empty chunks
     .LastOrDefault())                // take the last chunk (or null) from the split    
  .Where(email => !string.IsNullOrEmpty(email)) // filter out null or empty emails 
  .Select(email => new ListViewItem(email)) // create a ListViewItem from email
  .ToArray();                         // materialize list view items into an array 

listView1.Items.AddRange(itemsToAdd);
