Send or Forward a document to "your workspace" to import it.

Each workspace has an e-mail 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

Note that only administrators and contributors of the workspace can send documents using the email address
