For a one off project you would click to create a one-off project, then select the timing, create your design, and add recipients in the editor.
For a recurring campaign it is essentially the same process, but the timing options are different and you would create a list under in Contacts section which the campaign will send to.
Drip campaigns are like multiple one off-projects strung together that you send to a dynamic list.
Advanced orders can be either integration orders or API orders. Both of those require a template.
