Mass send email? Need some advice!!!!!!

Hello guys,

I have about 30 thousands emails to send, but the verified hotmail account only allow 300 emails one day.

So do you guys know how to do this? The most important thing is that I should be able to reply to the emails if they reply to me.

I don't need to send 30 thousands in one day. It is OK if I can send 500 or 1000 emails in one email account in one day.

It means that I need a email server that allow me to send 500 emails by one email account in one day.

Do you guys know where I can find this?

Sorry for my poor english.

i use some contractors which i have hired form some community. they do this type of jobs for me
Actually i don't know the thing but i always do it while i have to give out something to my subscribers
