What are keywords?
A keyword is a unique word (or number) that is created for a specific short code SMS campaign. Multiple keywords can be used on a single short code active during a single period. The keyword is the actual text that a user keys in on their mobile phone to interact with a campaign.
Keywords are extremely useful for a few reasons. First, it enables the person sending out the mass SMS to collate responses in a functional manner. Second, it is a good way to gain opt-in consent from a customer without having to explain or run a campaign.
