Newsletter not being sent

I have sent out numerous newsletters to members who have it marked that they'd like to receive them, but they're not getting them, Admin included. I have searched my junk as well as my inbox but they're not arriving.

Does anyone know why thats happening? It's rather frustrating.

Are you sure they are ticked? and also are you making sure its not selected only to go to a certain group? or that you are cheking for the right email address? as on mine i have maybe 4 emails i can send it from.

I am positive that all the admins have their boxes ticked and I send it to everyone.
I'll try the email address thing, thanks for that.
