When a send is initiated directly to a Sendable Data Extension that includes records targeted for deletion, the following behaviors are expected:
* Records still in the suppression phase will be excluded from sends (B)- These records are in the process of being deleted and will not be included in the send.
* Records that have been deleted will be excluded from sends indefinitely (D)- Once records are deleted, they are permanently excluded from future sends.
