Blacklisted Email Addresses

On the Blacklisted Email Addresses tab of the Email Services page, you can manage the list of email addresses that have been blacklisted to prevent the program from sending email to them.

When you run the email status process, the program records any email addresses that return hard bounces and adds them to the blacklist. A hard bounce indicates a permanent delivery failure such as when the Internet Service Provider reports that an address is canceled or nonexistent. The program does not blacklist soft bounces that indicate temporary delivery failures such as network issues or full mailboxes.

You can also manually add email addresses to the blacklist to prevent the program from sending email. For example, you can blacklist email addresses that you associate with malicious or fraudulent activity.

You cannot remove email addresses from the Blacklisted Email Addresses tab, but you can update the status of email addresses to allow the program to resume sending email.

The Blacklisted email addresses grid the blacklist status of email addresses, the number of failed delivery attempts, and the most recent notification message. To filter the grid by blacklist status, select Filter, select a status, and select Apply. To remove the filter and view all addresses, select Reset.

To search for a blacklisted address, select Search addresses On the Email Services Invalid Account Search screen, enter your criteria and select Search. Under Results, the email addresses that meet the criteria appear. For each address, you can view information such as its blacklist status and number of failed attempts. To return to the Blacklisted Email Addresses tab, select the address to view.

Note: For email addresses that return hard bounces, the program synchronizes the Blacklisted Email Addresses tab with Invalid accounts in Blackbaud Internet Solutions. However, the program does not synchronize email addresses that you manually blacklist, so these addresses do not appear in Invalid accounts. When you mark an address as valid in Invalid accounts, the program automatically toggles the status on the Blacklisted Email Addresses tab. Likewise, when you toggle the status of an address on the blacklist, the program automatically marks it as valid in Invalid accounts.
