Processing feedback from the blacklists is a manual process for Marketo’s Privacy team. While we try to get the reports out to you on a daily basis, sometimes we get back logged and notifications may not go out the same day that you triggered the blacklist.
But not to worry: most blacklists are dynamic, meaning that they resolve themselves after a given time period or when email statistics improve. Typically blacklist issues are resolved after 24 hours, so chances are you are not still being blacklisted.
Still, you need to complete the blacklist remediation program to identify the source of the problem and ensure that this doesn’t happen again. While most blacklist issues resolve themselves, they can have a noticeable impact on deliverability. Furthermore, being blacklisted is an indication that you have a problematic data source in your lists that could lead to even bigger deliverability problems.
