Need to Inbox about 1000 emails per day

For my marketing campaign I need to inbox 1000 emals everyday.
What I wanted to do is email them using a big provider like hotmail or gmail but these both have limits.
It is really important that these emails hit the inbox because sending 1000 to spambox does not deliver any good results.
I read something about the godaddy method but I am not sure if that is working and how this works.
Can anybody give me some tips or advise on this?

1. Get double-checked valid email addresses list
2. Use aweber.com to send emails.
3. If you don't use Spammy words much within emails, hope them to be delivered to the inbox not to spam folders.

Thanks! But does aweber like it when it are 1000k new emails everyday? Or do they dont mind that you keep changing the subscribers?

Try GetResponse. They should be able to help.
