Some more Information

Scope of Suppression

When you setup a suppression list, you will be having this option to either suppress the contacts globally or suppress the contacts for specific list only. No matter in which list the contact is placed, if it is suppressed globally no further messages will be sent to that contact. On the other hand, if you make your choice of  some particular list while setting up the list for suppression, the contacts will only be suppressed for that specific selected list, if the same contact exists in some other list, it will not be omitted while sending.

Some other numbers that the client account will not be able to send are the numbers that are being suppressed by the admin. There are possibilities that some numbers are suppressed by the admin, i.e. numbers that may belong to specific National Do Not Call List etc. This admin managed suppression list will automatically be applied to all the client accounts as well.
