Best multilanguage newsletter there is. I had some dificulties but resolved everything on the support forum. I recommend it to all, and think it lacks just two things to reach perfection:
More statistical data on clicks in newsletter ( not just who viewed newsletter out of their email inbox, but even which articles were visited etc. )
And a tutorial for creating newsletter template from scratch ( I know there is a tutorial based on an existing template, it might be nice if we could get one from nothing to something ). Maybe even a plugin site section where users could post their own free newsletter templates.
