# Uploading Unsubscribed Contacts

When first onboarding to Cymbal from another provider, we highly recommend uploading a list of your existing unsubscribed contacts to ensure compliance with [CAN-SPAM](https://www.ftc.gov/business-guidance/resources/can-spam-act-compliance-guide-business) and [TCPA](https://www.fcc.gov/sites/default/files/tcpa-rules.pdf) requirements.

**Steps to Upload Unsubscribed Contacts**

1. Go to [**Audience**](https://manager.cymbal.co/audience) tab
2. Click **Add contacts** (top right)

6. Map your CSV fields to **Cymbal attributes**:

* Left column = your CSV column names.
* Middle = assign each to the correct Cymbal field (e.g., email, phone, first name, last name).
* Right column = preview of your CSV data for accuracy. Click **Continue**.

7. Cymbal will process your CSV (this may take a few minutes). Your **audience size** will update once complete.
