## What you control

| Control | Where |
| --- | --- |
| Who sees what | Team roles limit access by function. Only the Owner sees billing — see [Team and roles](https://support.unifunl.io/en/help/account-billing/team-and-roles). |
| What the agent must never say | The **Never do** list in [Agent behaviour](https://support.unifunl.io/en/help/ai-center/agent-behavior) — never make a medical claim, never guarantee a delivery date. |
| When a human takes over | The escalation rules: disputes, refunds, high-value orders. |
| Traceability of what was sent | **Settings**, then **Message logs** — the delivery history of every outgoing message, across all channels. |
| External system access | API keys are read-only and can be revoked individually. |

## Audit what was sent

![Message Logs: delivery history of outgoing messages, by agent, date, status and channel.](https://support.unifunl.io/help/screenshots/41-message-logs.jpg)

Filter by agent and by period to audit what went out and to check for delivery failures. This is the record to reach for when a customer says they never received something.

> **Good practice for your own screenshots** — if you share captures of the platform for training, social media or support, mask your customers' names, phone numbers, addresses and photos. That data belongs to them.

## FAQ and troubleshooting

### Do you use my customers' information?

Your information stays confidential and is used only to provide the service. It is not used for other purposes and not shared with unauthorised third parties.

### A customer says they never received a message

Open Message logs, filter to that period and channel, and check the delivery status. A failure there tells you whether the message left at all.

### How do I stop the agent saying something specific?

Add it to **Never do** in Agent behaviour, as one short sentence. That is the most reliable guardrail available.

## What's next?

Give external systems controlled, read-only access to your data.
