Email blocking is when an ISP or domain denies the delivery of an email.

Within your Acoustic Campaign organization, we provide a list of domain names, local prefixes, and system domains to which marketers cannot send unsolicited email, including email sent through an API call.

Domains tab

A list of domain names to which marketers cannot send unsolicited email is shown on the Email blocking screen which is found under Settings. Domains can be restricted because the messages go to wireless devices, such as cell phones, or because requests have been made to not send to these domains. Although the system list of domains is included, you cannot delete system domains. You can delete only domains for your organization.

When support enables the local prefixes option, all the existing domains will be removed. You will need to click on Synchronize with system to get those prefixes restored.

System domains

System domains is a list of domains to which Campaign prevents emails from being sent. This list is for reference and is not an editable list.
