If you are using a scenario to send the distributed mailing, you do not need to carry out any configuration steps for the mailing itself. If you are sending the mailing programmatically, perform the following steps:
Set the
batchedproperty in theTemplateEmailInfoImplobject to true on the machine that will initiate the mailing. Do not set this property to true if the mailing’s recipient list includes transient profiles.Optionally, you can also set the
batchIfPossibleproperty of theTemplateEmailSendercomponent on each machine to true. With this property enabled, thebatchedproperty is set to true automatically if a mailing’s recipient list contains no transient profiles.
