We need the following options added in mailwizz emailing platform.
1. Pay as you go: So that we could add buffer emails to clients without changing their actual group.
2. Credit Log History for the client: If the credits are added from back end to the client's account, it should be visible from client panel.
3. Credit roll-over: If we have a plan for 1 million emails and the client buys 2 times, then he should receive 2 million emails.
