Odoo ensures that all cases are successfully tracked by users, customers and suppliers. It can automatically send reminders, escalate the request, trigger specific methods and lots of other actions based on your own enterprise rules.
The greatest thing about this system is that users don't need to do anything special. They can just send email to the request tracker. Odoo will take care of thanking them for their message, automatically routing it to the appropriate staff, and make sure all future correspondence gets to the right place.

The CRM module has a email gateway for the synchronisation interface between mails and Odoo.
