Thank you for the suggestion. We'll surely take care of it in the coming future. Currently, we sending hierarchy is very different as compared to the other emailing applications available on the internet. We are focusing a lot more on automation and artificial intelligence in email marketing. With our current sending process, you can put limits on the user account level and the campaign level that does massive handling for a single or even multiple campaigns for multiple users. We are working on limiting sending nodes, sending domains, broadcasts as well but everything has to be super stable and based on queues, so we expect to launch it sooner or later.
