Select the a metric box you wish to target. For instance:

Choose the "Clicked Link" metric to retarget contacts that clicked the link from the original broadcast.
Choose the "Replied" metric to retarget contacts that replied to the original broadcast.
Choose any Tag metric to retarget contacts that had that tag added to the contact as a result of the broadcast.
Choose "Cancelled" metric to retarget contacts from the original broadcast that were not sent messages as part of this broadcast.

After selecting "retarget", the broadcast creation menu will appear with the selected engagement status or tag as the filtered audience. Proceed to complete the Broadcast wizard as per normal use.

Note that in the Wizard, it is possible to augment or restrict the retargeted audience. For instance, you can still add contacts on other lists or exclude retargeted contacts with a given tag.
