No, I tried all the most known:
YaNC, because was integrated into CB = but I had problems with send out email with delay time, step by step with seconds pausing, for server limits. I tried to solve but I was no able.
Letterman, because too clear = but have no delay time settings and it is only for one list, no mialinglists are allowed
PHPList, because most famous and I have into Fantastico on my server = but too complicated for me. Not integrated in joomla, just one no free bridge (that have also some bad reports)
ANJEL, because I found the CB plugin = after a small bug fix it seem run very well, just not so upgraded with images, layout and so on.
So, thinking a Newsletter components don't have so much developments/upgrades, and also hearing Beat want develope/support/integrate a very good Newsletter components I suggested:
forum.joomla.org/index.php/topic,60524.msg350211.html#msg350211
I think add forces is most clever, have a very good joomla components more usefull for all
PS the only technical request for me is to find a solution to send out big mailings with 1 click don't needing take open the browser on PC ... this is the best upgrade (may be just saving in automatic a file report on server when all is done)
Hooping this will help all us ...
