The Emulate mode is used for testing to help determine which customers would receive which campaign communications on which days without actually sending any live communications.
To set a campaign to Emulate, check the box above the touchpoints section.
Once this is checked and the campaign is set to Go Live, messages will not actually be delivered. Instead, campaign send stats will update to show what delivery would look like, to understand the cadence of the campaign.
Emulated campaigns are used to understand the frequency with which these campaigns will send when evaluating a campaign based on rare behaviors or which is part of a priority group.
