The sync table of the Gmail pack imports all emails from your Gmail account. The “To” column is used to extract only the emails sent to the general inquiry account. This extraction is carried out by an automation which copies the rows with a matching “To” field to the table of Incoming Inquiries.
An additional automation checks if the sender belongs to the list of spammers. If this is the case, the email is copied to the bin, marked as [SPAM].
