With MobileConnect, are mobile numbers that opted-out applied to all contacts that may share that number within MobileConnect?
Example below:
Contact 1
Contact Key: 12345
Mobile: 123-456-7890
Contact 2
Contact Key: 67890
Mobile: 123-456-7890
If Contact 1 opts out, will MobileConnect automatically exclude Contact 2 from receiving any further SMS messages because that mobile number is shared? Or is strictly specific to the Contact, similar to Email Studio?
