SMS COMPETITIONS

Run SMS competitions with two-way SMS

If you want to run a promotion that makes it easy to enter a contest, sweepstake, or prize draw, an SMS competition where people send a text message to participate is the right idea. Participants typically text a designated keyword to a short code or long number. Sinch Engage supports two-way SMS, dedicated short codes, and an inbox to manage incoming messages.
