There are two key elements when advertising your texting service: the keyword and short code. The keyword is a phrase or word that's synonymous with your brand, or a word you want to be. Non-subscribers, people who have not yet joined your contact list, will text this keyword into a 5-digit number called a short code. When they do they, they will have joined your contact list, and be added into a group that corresponds with that keyword.
The standard way of expressing this is:
"text KEYWORD to SHORT CODE to join"
How To Find Your Keyword and Short Code
In the top right corner, you will see your short code. If you do not, contact your sales representative so you can be given one.
If you do not have one or have more than one, your account will say View Numbers which will show you all the numbers on your account.
Click on Groups & Keywords tab in the side bar to find/make/change a group's keyword.
Click on the Edit Group button to find its keyword.
You can see your current keyword or an empty box next to Keyword. In this box, you can type in a new keyword.
After typing in a new keyword, press Check Availability! If no one is using it, its yours.
Hit Save Group at the bottom.
