Hi,
I have gone through your requirement and I want to share something with you.. Currently we are making a bulk emailing software, which will be get ready within one month. The software we are making is as per your requirement..\
Software is not for sale but for providing you emailing facility.. Right now we have not decided per email rate. SO if you are interested to get this service from us than we can provide you best service than any other emailing service.
Hopefully you will get interested to work with me in future,
Thanks and Regards,
Vaibhav R.
