Steps to Upload Contacts

  1. Go to Audience tab: https://manager.cymbal.co/audience

  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. Choose how to handle Email and Text subscriptions:

  • Subscribe everyone – marks all contacts as subscribed, even if they previously opted out.

  • Subscribe only if not opted out – adds contacts without re-subscribing anyone who unsubscribed.

  • Unsubscribe everyone – marks all as unsubscribed.

  • Unsubscribe only if not subscribed – unsubscribes only those not already subscribed.

  • Don’t change subscription – keeps current subscription status. Click Continue.

  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.

⚡ Note: Only contacts with explicit consent may receive emails or texts.

  1. Add tags or lists to organize contacts:

  • Tags: Internal only, customers cannot see them. Used for segmentation and tracking.

  • Lists: Can be public or private. Customers can subscribe/unsubscribe if public. Used for managing preferences. Select tags and/or lists, then click Continue.

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