We use text messaging via Core to notify parents of unplanned emergency events (school closures or late starts due to weather, etc.). I've discovered that I have to fit the entire message within the subject in order to avoid requiring the recipient to login via the auto-generate url to access the message. These texts need to be read immediately, without requiring login on their phones (most simply wouldn't get the message due to the added steps and not knowing their passwords offhand).  Because parents have already opted into receiving these texts, requiring them to login to read them seems unnecessary and cumbersome. It would be so much for efficient and readable for the recipient for the subject and message to be sent in their entirety, without login via url.
