Self Service

If you wish to clear the deliverability issues yourself, there is a two step process.

1. The first step is to contact each blocking domain and request removal from their block list.
2. Some providers will give you a URL in the bounce message that will tell you where to go to request removal from the block list.
3. For other providers, you will need to search the web (Google works well for this) to find the Remove from Block List (RBL) page for the provider.
4. Once you have confirmation from the provider that your IP address has been removed from their block list, you can remove the domains from ListManager's MailStream Block List.

Note: The mailstream block functionality is useful for holding off sending to domains that are known to be blocking. Once that block is removed for the domain, sending can be resumed by releasing the mailstream block.

Releasing a Mailstream Block:

1. Navigate to "Reports : Deliverability Dashboard"
2. In the "Top Domain Status" section of the report, click the "view blocks" link.
3. To release an individual block click the "Release" link for the block.
4. To release all blocks for the mailstream click the "Release All" button.
