Contacts will not be imported if they don’t have a first name, last name or valid email address. Contacts must have unique email addresses. Two different contacts cannot share an email address. If a duplicate email address is detected, you will be asked to select which contact should be imported.
If a contact is already in your address book, you will have the option to update the contact’s information with the new information contained in your import file.
If we detect the same first and last name of an existing contact, but a different email address, you can select to accept the new address for the existing contact or create a new contact.
