Why do iMessages turn green?

A green bubble means the message traveled as SMS or RCS instead of iMessage. That happens when the recipient cannot receive iMessage: they are not on an Apple device, they turned iMessage off, they have no data connection, or the number is a landline or VoIP line. Green is a routing fact about that recipient, not a penalty on the sender.

For outreach, the color carries signal before you send. Checking iMessage availability up front sorts a list into contacts who will get the blue-bubble experience and contacts who will get carrier SMS, which changes what you write and what rules apply to the send. The green bubble entry covers what recipients read into the color, which is not flattering.

For an individual thread that used to be blue and turned green, the recipient's situation changed: a switched phone, iMessage disabled, or a dead data connection. Delivery states on each message report which route carried it, so the thread history answers the question per contact.

The strategic read: green is the default state of business texting, and it is precisely what buyers have learned to ignore. Why the two experiences diverge so hard, and what that does to response, is the subject of blue bubble vs green bubble.
