All About Keywords!


Many of you have come to for keyword campaigns. Keywords are initiated by mobile subscribers. They tell what the subscriber is looking for or wants to do.

There are three types of keywords maintained in the by The developer can choose to control only the opt-in and responder keywords. retains automation rights over any STOP or HELP request. The three types of keywords are:

Opt-in Keyword

This keyword, when initiated by a mobile subscriber will immediately opt them into the store that is assigned to that keyword. The mobile subscriber will thus be known as an opted-in subscriber to the store and will assign a dedicated short code for the store and customer to communicate with for the life of the opt-in. Since the customer is opted-in, you now have permission to send recurring messaging.

You can respond to opt-in keywords dynamically, but it is not recommened.

Responder Keyword also provides the ability to set a keyword as a responder only. When initiated by a mobile subscriber the responder keyword can only return ONE response, which comes from our marketing short code (444999). There is no change to a subscriber's opt-in status when this keyword type is triggered. It is generally used for one time coupons or general information requests. Use of a responder keyword by a subscriber does not enable them to receive recurring messaging and they do not become opted-in.

Responder keyword responses can be automated by the SMS API or you can respond dynamically if you wish.

Global Compliance Keywords

For compliance reasons, the following keywords cannot be reserved. They are; STOP, END, QUIT, UNSUBSCRIBE, ARRET, CANCEL, HELP, INFO, AIDE, YES, YEA, YEAH and NO. These keywords are automated by the SMS API for compliance purposes.

Wildcarding Keywords

The API does allows wildcard keywords. For example, let's say you register keyword CLOUD to one of the marketing short codes, 444999. Any message received to 444999 with the keyword CLOUD will be posted to your store. But so will the rest of the body of the message, as long as there is a space after the initial keyword! So......if a subscriber sends you CLOUD WIRE or CLOUD IS GREY, the SMS API will post both messages to the store you registered the keyword in.

However, keep in mind that the SMS API also supports creating keywords with spaces. Take caution in the fact that if you intend to run a wild card campaign that some other Client might have registered the keyword CLOUD IS GREY.

Wild card keywords are best used for asking subscribers to text a keyword and then a space followed by either an email address or a coupon code.

There is no charge for wild carding! So in the above example, only CLOUD is a billable keyword.

Keywords After Customer is Opted-In

It’s important to note that you can create keywords within your application as well, but only AFTER the customer has opted-in to your store! If you want to do responder games or surveys, use the opt-in keyword or Send Opt-In method as your first path to get the mobile subscriber opted-in.

Once done, you can assign any keywords (Except for the global compliance STOP and HELP keywords) outside of the SMS API because the Customer is already opted-in to your store. You can use the inbound listener to listen for the keywords you want to respond to. There is no keyword charge for internal keywords because they are not registered to the marketing short codes.
