Hello guys! We are currently thinking about offering email marketing service to our clients though we have to decide whether we are going to do it on our servers with a software like 12All or we are going to resell it from another company.

We are absoluty decided on 12All as the software if we are going to manage it, but I'd like to read your feedback on the reseller options. Googling gave us hundred of options (like ZebraTracks or StreamSend). Do you have any experience with any?
