Keyword campaigns are the most effective opt-in mechanism.

Building and maintaining a list of clients and leads is the most effective way to generate continuous business. SMS keywords are a simple way to allow people to opt-in to your lists as well as a powerful and immediate communication method. Try texting the words on the right to the number shown. A keyword acts like a trigger that when sent to a virtual number can activate different functions like auto responders, forwarders and adding to lists.
