To send the messages of an email job to LISTSERV, the delivery of the job must be authorized.
Once delivery authorization is given, the job will begin delivery immediately, or will wait in the ongoing jobs list for the scheduled delivery date and time, as was specified on the Delivery Settings screen.
The Authorize Delivery screen presents a final overview of the job so that the job settings can be verified as correct and the message appears as expected.
To authorize delivery, click the [Authorize Delivery Now] button.
The Authorize Delivery screen also displays the list of currently defined delivery notification addresses (if any). After delivery (that is, after the actual delivery, not immediately after the authorization), a notification email about the delivery status will be sent to all email addresses shown here. Click the Change link to change the notification addresses. If no addresses are supplied, then no delivery notifications will be sent.
Note: If the job is using auto-repeat delivery, the overview screen also shows the delay interval between repeats, the scheduled end date/time of the extended delivery (if any). If the job is an auto-repeat sequence of job copies that is now being re-authorized after its original authorization had been revoked, there may be a choice to keep the job as part of the same auto-repeat sequence as before, or have the job start a new auto-repeat sequence. See here for details.
Note: If the job was defined with subscriber list recipients using the "Recipients Selected On Demand By API Calls" option, then the authorize page does not include the mentioned delivery notification address options and authorizing the job will also not cause any emails to be sent at this time. Instead, it simply authorizes the job to stand ready and accept API calls, which then in turn trigger the delivery of actual emails.
