The idea is - an inbox app like Gmail, where you can create multiple email ids like username.id1@zmail.com, username.ide2@zmail.com and so on. Each id will be single purpose only, meaning it is only capable to receive emails from one sender like ...@amazon.com. If someone else sends email to that id, it will simply be dropped. It will be a receive only app with no email sending feature. It will have a Whatsapp like UI and chat like bubbles where emails from the sender will be summarized. Further, financial insights can be provided based on the emails in future.
What do you think about it? Would you willing to use it for free or a small fee?
