Can I change the pre-header text for an email?
On the Schedule page of your email campaign, you are now able to optionally assign an audience or group to receive the message. You choose which of your created groups to send your communication to, and if you so choose, you can also specify which audience as a part of that group to send to. Please note that if you specify an audience, your email will only be sent to that audience and not the entire group.
