We don't currently have a subscription level that allows more than 10K emails sent per month. The reason for this limit is that we are not promoting the software today as a mass email marketing platform. Our solution is more of a sales prospecting platform and with how we have designed the system 10K should be enough for sales prospecting.
If you are looking for a system were you can send out tens of thousands of emails everyday in more of a mass email marketing way, we are probably not the right platform for you. Or at least not right now. We may evolve in the future to support that but we are not there today and it is not in our current roadmap.
