[kingsport]

Hi, so shopify automatically send sms notification after order is made, if the customer add his phone / not mail. What i was thinking, i am doing COD , is there a way to add in the sms a message like this, if you change your mind about order please cancel it here > link for cancel order. Is there something like this i can do ? Thank you very much!
