WOW.  this is simple!  HB, Export View (after selecting clients who fit your blast profile).  Then open excel and open the CVS file under PS2018.  Then cut and paste their emails into BCC in your fav email program.  And I thought this was way too tech!  Glad I gave it a try.  Sad I did not do this years ago.  I am not tech savvy - give it a try.
