Select the campaign you wish to create a keyword for by clicking the Manage button from your list of campaigns on the campaign dashboard.
Click the Settings icon in the campaign navigation bar in the top right hand corner of your campaign home screen, then click on General.
Enter your desired campaign name in the field below "Campaign Name". Don't worry you can change this at a later time. Campaign names are only visible to you, and are never seen by your customers.
Click the Save Changes button at the bottom of the screen.
If you're looking to set your SMS keyword, which is different than your campaign name, click here.
