 * 3. `publish` the content template (in the future, this will instead happen when the campaign is modified)
 * 4. `prepare` for the run (if the method is implemented)
 * 5. `deliver` the content to batches of recipients with substitutions
 *
 * Outside of the campaign run flow, a channel must also be able to `preview` a given piece of content for a batch
