Opt in to Receive Messages
Contacts who opt out of receiving messages no longer receive one-way messages, including emergency alerts. Contacts can opt back in to receive one-way messages.
If the contact still has a messaging thread on their phone, instruct the contact to reply Start on the message thread to opt back in.
If the contact has no messaging threads on their phone, you must locate the contact's unique KiNVO number.
From the main menu, select Kinbox in the Messaging section.
Click a message, and then choose More Info to display the KiNVO number.
Share this number with the contact and instruct the contact to send the message Start to the number.
