It is mandatory to get consent from a mobile phone user to send them text alerts. If your mobile phone users have already consented to receive text alerts previously through a different platform or option, you can start sending them text alerts. If they haven't consented previously, we recommend sending users the option to opt-in by replying "Yes." You can create a keyword auto-reply with the tag "Yes" to know which numbers have consented.
