Each of your workspace has a private email address you can send documents to
To access it, go to your connected apps, scroll down and notice the e-mail address.
Double click on the contact card to add it to your e-mail client contact list so you don't have to remember the list of numbers and letters
You can send send documents in attachment directly to your workspace or just forward e-mail threads. Zendoc will just extract the attachment and import it into the workspace
INFO: Only workspace's administrators and contributors can send documents using the email address
