    The message From/To pair violates a blacklist rule when sending pin text


    The API will return this message if you attempt to send an SMS or MMS to a recipient who has previously replied STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT to you.

    To be able to send messages to such recipients, they must first text START or YES to the number to opt in again.

    So to resolve, they’ll need to send a text to 248.243.6647 with either START or YES to allow the Text Message go through.
