Uploading Unsubscribed Contacts

This page shows you how to upload unsubscribed contacts to ensure compliance

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 and TCPA requirements.

Steps to Upload Unsubscribed Contacts

  1. Go to Audience tab

  2. Click Add contacts (top right)

  1. Select Upload CSV

  1. Upload your file by either:

  • Clicking Choose a file, or

  • Dragging and dropping your file onto the screen

  1. Unsubscribe everyone – marks all as unsubscribed.

  1. 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.

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