If the number of contacts on Mynewsdesk after import is smaller than the number of names in the imported file, this may be due to contacts
– in your list without email address
– that hold duplicates within your list
– that are already saved to Contacts on Mynewsdesk
– who have previously requested a complete removal of their data from Mynewsdesk
