Podium and Wondersign both use Twilio to route text messages through the customer's carriers to successfully deliver the link to their cart. Twilio will block messages that appear to be spam to protect mobile users. In some cases the link used to identify the cart will be marked as spam and fail to send the message. In addition, carriers filter messages to enforce the rules, as well as prevent spam and other forms of abuse.
