We host a portal for the citizens & as add-on value, we offer a free mailbox service. Our marketing chaps blast marketing mails to subscribers of our mail service (which is also owned by us) so we're authorized to 'spam' marketing newsletters to those who signed up with us.

Some subscribers use their external gmail/hotmail & agreed to receive newsletters from us too.
