When you save a newly-created email channel, or when an existing email channel's Recipient email address field is changed, a Validate channels job is created.
The job creates a join is between the email suppression table (as defined by system configuration setting EmailUnsubscribersTable) and the Recipient email attribute's resolution table.
The following additional columns are added to the offer history table if they if do not exist already:
•Selected
•Sent
•Delivered
•Opened
•Unsubscribed
•ClickThrough
•HardBounced
•SoftBounced
These columns are used to store additional channel-specific state information – for example, indicating whether an individual clicked on a URL in an email delivered via an email channel.
Following the job’s completion its status is set to Completed, and a View Results button is shown. Clicking the button displays the Channel Validation Results dialog, which details the nature of any issues that occurred during the job’s execution.
