To create a campaign, simply use the New campaign option. This can be selected from the Campaigns dropdown menu from the navigation bar.
Or you can also choose this from under 'Popular actions' when on the dashboard page.
Alternatively, you can select Campaigns (or My campaigns from its dropdown menu) from the navigation bar and then click on the New campaign button on the 'My campaigns' screen.
Another way is to select Campaigns > My templates.
If you have them, preloaded templates will be displayed within the main area of the screen. By dragging the scrollbar, you can move through the templates until you come to one that suits your proposed campaign layout. Remember - all of these templates can be edited.
To see a template in more detail, mouse over the template and click on Preview.
When ready, click on the New campaign button to create a brand new campaign based on the selected template.
