# SMS and MMS Send Status

Outbound SMS or MMS messages carry a status that describes the current state of the message, which is displayed in the Conversation Timeline.

The table below displays an outbound SMS or MMS transmission status.

| **Status** | **Description** |
| --- | --- |
| **Sending** | Gladly is in the process of sending the message. This status is usually only present for a very short time and quickly change to *sent*. |
| **Sent** | Gladly is in the process of sending the message. This status is usually only present for a very short time and quickly changes to *sent*. |
| **Delivered** | Gladly has received confirmation of message delivery from the carrier. This means the message was successfully delivered. |
| **Failed** | Gladly has not received updated delivery information for your message. Typically, a sent status will be replaced by a *delivered* or *undelivered* status within seconds or minutes. Please note that US/Canada long code MMS often remain in *sent* status due to a lack of final delivery status updates from carriers, but the message was successfully delivered. |
| **Undelivered** | The message could not be sent. This can happen for various reasons, including queue overflows, account suspensions, and media errors (in the case of MMS). |
| **Unknown Error** | This could be due to many errors, including carrier and ISP-related errors, but the most common reason is that the phone number being used has not completed [A2P Registration](/docs/toll-free-number-verification-and-a2p-10dlc-registration-process). Carriers block messages from an unregistered number. |
