It would be better if it were "pay-per-user" instead of "pay-per-account." For example, I'm Siddharth Mallya, and I have two email accounts. Each of those accounts is a separate payable account for me. For instance, I have created a network using my personal email ID, and now I have moved to my company email ID. It'll choose any one of those accounts, and that will become my paid account. For example, if I put in my personal email ID, then that's the account that I pay for. But I'm no longer using it, and it's not going to get updated. If I put in my work email ID, then that's an entirely separate account that I have to pay for.
