By US FCC regulations, you must allow users to unsubscribe from Text/SMS notifications. CivicReady has short codes that send out day-to-day messages and emergency alerts. These short codes allow users to unsubscribe as well.
With text messages, users can just reply to any message they receive with the word STOP and they will cease to receive messages from that short code. If they would like to resume them, they can simply find one of those messages reply once again to that short code with the word RESUME and that will allow them to receive messages again.
