How to build marketing from INBOUND SMS messages like "Text ZEBRA to ... and enter our raffle"

Is there any ability anywhere in the Zoho ecosytem which allows for inbound SMS messages purposed for marketing? I'd like to create a raffle or giveaway where participants enter by texting a word to one of our existing Zoho phone numbers. 

Does anything like that exist?
