Newsletters

Are there any quality newsletter software or white label programs with available bulk content or PLR articles industry specific and general information ( if not I guess these could be bought separate and inserted each month), games ( crossword puzzles, sudukos, ect), trivia, contests, where you can just insert the industry specific content and one that can work for both platforms as in enewsletters and traditional mailers? Not looking for a system where someone would do the newsletter for me but a quality software or white label program that I could utilize for myself and possibly others.

A while back I ran across a white label newsletter program like I am describing but I cant remember where. You could have it set up where the customer could log in ( membership) and enter their own specific industry articles, make alterations, insert sponsor advertisements if desired, insert logo, it was very versatile. Once they had it the way they wanted it the way they wanted it, they could either send it to a local printer and mail it themselves or send it to a internet printer and have them mail it for them. It could also be used as a enewsletter.

Does anyone know of a product like this? If not maybe someone with more knowledge in that department than myself should create such a product. Whats your thoughts?
