Unconfirmed messages are messages that are successfully sent by TextUs, but failed to receive a Delivery Receipt (DLR) from the recipient's carrier.
This animation means that the message has been sent, but we are waiting to get a Delivery Receipt from the recipient's carrier that the message has been received:
If a message doesn't receive a Delivery Receipt after the specified amount of time, the message status in TextUs will switch to Unknown:
Delivery Receipts are not guaranteed from the carriers, and most of the time if you see the ... animation or the Unknown status, your message has actually been received by the recipient!
(Note: Unconfirmed messages will log as an integration note within a couple hours of being sent)
It is normal to see this happen every once in a while, but if you are seeing it on every message this could be an indication of an issue with your phone number or our Provider. Please reach out to Support if you have any concerns!
