Why this rule existsrationale
The confirmation has the longest required element list of the three auto-replies — brand, programme, frequency, rates, HELP and STOP — so it is the one most likely to overrun. Truncation drops the tail, and the tail is where STOP lives.
How to fix itremediation
Compress to 255 characters while keeping all six required elements. Abbreviate "Msg & data rates may apply" rather than dropping it.
A compliant exampleexample
Acme Coffee: you're subscribed to offers. Msg frequency varies. Msg & data rates may apply. Reply HELP for help, STOP to cancel.
