# Send the update. Keep the reply.

Give customers a number they can answer. Connect incoming texts to the order, appointment or support request behind the conversation.

## Turn incoming texts into useful replies.

Receive texts on an eligible number. Reply from your app, or connect the steps in a Bird automation.

Illustrative SMS reply workflow. Send acceptance is followed by a carrier delivery receipt, not a read receipt. No messages are sent from this page.

## Receive the message. Reply with context.

Receive customer texts and reply from your application.

### Start with a receiving number.

Use a number that supports incoming SMS in the destination. A brand-name sender cannot receive replies. Match the inbound destination to the number your application owns.

### Use the incoming event.

The sms.received event carries the message body and both numbers. Correlate it with your customer records, then choose the next action. An incoming reply is distinct from a delivery receipt.

### Handle keywords before business logic.

Supported stop keywords create a suppression and still emit an incoming event. Keep that outcome in your application’s reply handling so an opt-out does not accidentally trigger another promotion.
