A new postal mailing module lets users send invoices and sales orders through the DocsAway service, either one at a time or in batches from list views. This gives businesses an integrated way to handle physical document delivery directly from Odoo, with a test mode available in settings before going live.

...This module uses the DocsAway web service. It allows to send single documents or multiple ones (thanks to selection in list views). Here, invoices and sale orders are ready to use

To test the module, don't forget to check the Test Mode box in General Settings.
