If you have a new supplier or a client emailing documents to your folder, first the emailed documents stop in the spam protection filter until you approve them. You can also delete the emails.
Here is a quick overview of all available actions:
Process email (only this email)
Process all emails from this sender
Delete (this email)
Delete all emails from this sender
If you wish to approve email addresses of your suppliers, clients or staff members upfront, you can add them to the 'Email whitelist' in Datamolino. Please go to the 'Folder settings', and then to the option 'Email Import'. Here you can add multiple email addresses which will be allowed by Datamolino for all later imports of documents.
