Where is my campaign saved?
When you save the campaign, it is saving your changes in the Content step. The campaign can then be accessed from the Home page under the In Progress tab or from the Campaigns tab.
Once the campaign has been sent, it is no longer saved in the In Progress section of your account, but it can be accessed from the Reports tab.
If you want to reuse a campaign, you can copy an in progress or a sent campaign by clicking the down arrow next to the campaign's name.
