For more accurate suggestions, you can classify emails into sections.

Classifying emails by sections helps EmailTree application to provide more and more suitable answers to emails.

Creating sections increases the accuracy of generating correct responses.

The more emails are passed through the learning process on a section, the higher probability that the proposed answer for a specific problem will be the correct one.

A relevant name must be chosen for each section, when creating a new one.

As training data will gather, the application will be more and more accurate in classifying the emails automatically.
Every section can have a different set of email blocks.
