Hi Itay, I stopped using this, as some spam reasons are only temporary. Example SpamCop is only marking the spam for 4, 8, 12 hours, and so so. This also happens because another customer on your shared Marketo server is sending SPAM. So why would you suspend marketing? You didn't do anything wrong and you do want to email that lead again within a certain period right?
I will only reactivate this (to improce trust score) when Marketo starts assigning IP's per customer.
