I just set up a Smartlist mailing list, and although I have the documentation I’m still pretty lost.  Last night I sent out the first message to the list and of course lots of the emails bounced.  I now need to unsubscribe those addresses.  I already have hundreds of addresses and expect to eventually have over 1000.  How do I find the address to which I need to unsubscribe?  I found that if I type in the first letter of the address an address beginning with that letter pops up, but then I have to keep doing this over and over to eventually find the right one.  There must be an easier way?  Thanks!  Lynn
