Why are contacts not added to my list when i use the listAddContacts method
Some of the common reasons why the contacts are not added to the list would be - The contact has not clicked on the confirmation email. You can check this by clicking on the "Not Optedin Yet" link in the contact listing. - The contact could be in your master unsubscribe list - The contact could be already present in your list
