Direct marketing without permission

iSAT is engaging in Direct Marketing without permission and sending emails to private email addresses not listed publicly.

They were not provided permission to send email to my domain nor to my other private email addresses.

I cannot go through all 5000 email accounts that most are users private mailboxes and go unsubscribe everyone from this spam.

You WILL NEVER get my business if you market via email without permission.

Disgusting behavior from a company I used to have respect for.
