Mass Mailing service with white label

Hello,

I'm considering mailing my leads for other people, like a solo ad provider. But in this case, I'd like that whoever will send the e-mail, would be able to create their own newsletters, and send them to a list that I make available, but which they couldn't see the contacts. And of course, after sending, they would be able to see the stats.

Anyone know if there is any service like this? Thanks!

if the leads aren't real optins, then you will lose the "white label" extremely quick. Your sender score will fall, and the company will kick you out. It's happened to me a dozen times.
