Define Recipients: Send to Recipients in the Subscriber Warehouse

To access the recipients wizard for a given standard mail job from the open job details pane, select the Summary tab and click on the Edit link in the Recipients section. If you are already on the workflow page of the mail job, simply click on the Define Recipients section.
To access the recipients wizard for a given A/B-split job, click the Edit link in the Recipients section of the A/B-split job details page.

Note: If the recipients do not have the desired type "Send to Recipients in the Subscriber Warehouse", you can change the recipients type on the source page.

The Define Recipients wizard allows the defining of recipients that will receive the email message specified in the job when the job is finally sent.

The wizard has up to five pages: Source, Source Details, Recipients Details, Advanced Settings, and Summary.

The top row of the wizard displays links to these five pages. The page that is currently open is highlighted. Depending on the choices made on some of the wizard pages, other pages may become disabled or may be shown in different versions. If a wizard page is disabled, then it means that this page is not necessary with the current choices and can safely be ignored.

Advanced Settings Page: Staggered Delivery, Recipient Counts

This screen defines advanced settings for the recipients handling.

You can enable Staggered Delivery to optimize the load balancing of your email server when you expect to have a very large amount of recipients. To define the settings for Staggered Sending click on the Change link.
The "Recipient Counts" section shows the number of recipients, if delivery were now.

Note: This page is not available if the recipients are added over time via external API calls.
