As a Marketer using SMS keywords, I want to be able to trigger journey automations when a Contact replies with my SMS campaign with a keyword.
Today MMC journeys have no SMS contact list related triggers, so when a contact replies with a keyword, and they are added to an SMS contact list, if the webhook was hit with that contact's information, I can have a middleware then trigger a journey to send an SMS reply.
Similar to how Email Contact lists have a webhook functionality that can trigger and inform an external service, this would be useful in SMS contact lists as well.

Of course, if Contact journeys had ways to trigger via SMS keyword reply, or contact added to SMS list, this would suffice as well.
