Email to SMS texing failing

Hey there. Message aggregation services like SendGrid should have all their ducks in a row to prevent your messages from being flagged as spam and blocked. That is mainly true for messages being sent through regular sms or email channels like sending to a phone number OR @emaildomain.com. There is an added layer for Tmomail.net that could be causing your messages to still fail. The email to text service is a VERY low volume service that is only designed for person-to-person messages. ANY business-related or high-volume messages can be blocked on that platform. You should be encouraging your users to provide a true email address or phone number instead of their tmomail.net to ensure message delivery.
