The very first step of the campaign creation process, using your Campaign Creation Wizard, requires that you type-in basic information about your campaign. One of the things you need to fill in is the name of the campaign.
The campaign name is for internal use only!
You'll be using the campaign's name to quickly and easily identify your campaign, so feel free to name your campaign whichever way you prefer. You don't have to worry about your recipients being able to see the name that you give it, because they won't. Fields such as the Subject Line of your newsletter, the Sender as well as others are clearly visible to your to your recipients, so you should make sure they're the right ones.
