Private message to subscribers

hello, i have youtube account with 20k subs, is there any possibility of sending same message to all of them? i know you can do manually one by one, but maybe there is some other way? thanks

doesnt matter i dont use that account , but is there any bot to do that?

I know that there used to be a way, but ever since the whole google+ thing came in, theres not much we can do besides messaging one at a time. Also, If you don't use the account, do you want to sell it? I wI'll pay good for that account. Just shoot me a PM, even if not interested, thank you!
