Making email more efficient – Would you use this?

I've been stuck with this idea for a while so, I thought I would post it here to get constructive and honest feedback.

Problem: Email has become a frustrating experience and we waste a lot of time when it comes to finding the emails we need to pay attention to and then later sorting them.

Solution: An email client that is based around self-organizing folders.

How it works: - In the pic above, the emails are sorted automatically into the folders as you receive them.

- You can drag and drop the email in any folder and the folder will learn your preferences and adjust accordingly.

- Emails are shown according to the vertical order of the folder arrangement under "Inbox" and NOT in chronological order for each day. This way, you can organize the folders in the order that is important for you to see the emails as they arrive.

- „Clear" means, that it just clears those emails from what you are seeing there (emails are still stored in folders) so there is less clutter.

Would you pay a monthly subscription fee of $5-10 for a service like this? If not, please tell me why.
