You need to check with your smtp server manager - to avoid being blocked. If you own the smtp server, than this is not a problem. I think the best way is to send them in bulks of 50 recipients per message (it will be a little faster than one by one).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
