No, it means up to 60 messages an hour with up to 8 recipients each.
Using this ISP for bulk mailing is a really poor infrastructure choice.
If you can't make better choices, you may be better off with VERP
(resulting in 1 recipient per message), and at most 450 messages per
hour via a rate delay of 8 seconds per message. With VERP you can also
determine, in a lot more cases, which recipient is causing persistent
bounces and must be removed from your list.
