# Send Status

When an outbound message is sent to a contact via SMS or WhatsApp, the message can either be:

* **Not send** - Phone number is invalid and hence the message is not sent.
* **Sent but not delivered** - Phone number is valid, but the message is not yet delivered.
* **Delivered but not seen** - The message has been delivered, but the contact has not seen the message yet.
* **Seen but not replied** - The message has been seen and delivered, but the contact has not replied yet. (Only for WhatsApp)

You can create the next steps of the flow based on the result of the message delivery.
