Hi,
Hope this finds you well; it's been almost a decade since we as a team catering the needs of infrastructure development/configuration for high volume email senders. We've managed to design and configure system capable of relaying millions of marketing emails daily, for the clients belonging to different industries. Let me know the volume of email data you are looking for? I'll provide details upon getting the numbers from your side. These are actively engaged consumers that have already tested for receiving marketing/ product promotion messages, and if reached properly, you can expect to generate optimistic results out of it. Moreover, if you are willing, we can also help you setup/configure mail server for large volume email delivery. I look forward to your reply, and hope to work soon..
Regards,
