Important notes about Keywords

  • They can be one or more words, space is an allowed character

  • The number of added characters must be a minimum of 3 and a maximum of 20

  • They can contain letters of the international ABC and numbers from 0 to 9

  • They can not contain special characters such as: ?, -, _, /

  • They are case insensitive, uppercase and lowercase will work equally

  • You can not create multiple opt-in tools using the same keyword, keywords must be unique

  • You can not use Help, Unsubscribe, Unstop, and Stop to set up a keyword opt-in tool

Once created, your keyword will appear on the Opt-in Tools Page. You can activate and deactivate it by clicking on the three dots next to it.

Please note that if people are sending the keyword to your phone number, but the keyword opt-in tool has inactive status, people will not be subscribed to your list. The subscription works only with an active keyword opt-in tool and with an active welcome message!

Keywords sent with special characters such as ?, !, -, etc will be recognized and will subscribe the user to your list.

On the same page, you will be able to track how many people subscribed to your list via the keyword opt-in tool in the Subscriptions column.

If you click on the keyword you can modify the attached welcome message, on the other hand, you will not be able to modify the keyword’s name. You will also find our recommendations about sharing your keyword on this page.
