I'd recommend strongly incentivizing current Koodo clients to push word-of-mouth marketing. One particular method could have client post pictures of themselves in Luchador masks for a day, perhaps without mentioning anything about Koodo it in their posts. Current clients will know what this means, and will praise each other for the quality of their masks.
This will likely draw the attention of non-Koodo clients, who may themselves adopt this fad. Perhaps those who wear masks for one day will be given $5 off their current tab. The idea is to incentivize spreading Koodo through kudos.
