Before you get started
Ensure the following before importing contacts:
You have access to Audience Manager.
Your file is saved as a CSV format.
Your CSV includes at least the email address (this is what we use for the unique identifier for each contact within Audience Republic).
If importing state data, the country field must also be included for proper recognition.
You’ve created any required custom fields beforehand (only plain text, number, date, or single-select fields are supported).
Tip: Avoid creating custom fields that duplicate existing system fields (e.g., don’t create another “Gender” field).
Formatting Your CSV
Required fields:
Email address
Recommended optional fields:
First name / Last name
Phone number (mobile formatting guide here)
Gender, DOB, State, City, Zip/Postcode, Country
Tags, Lists
Formatting tips:
Mobile numbers must include country code. Use the format: +1 5551234567 (no brackets or dashes).
Columns that don’t match an import field should be removed.
File size must be under 100MB.
Download the CSV template for reference.

Re-importing Data & Unsubscribed Contacts
Important: Re-importing an entire contact list may resubscribe fans who previously opted out.
Best Practice:
Use segments to import only new or updated contacts
Apply the filter “Subscribed to list”, export that segment, and re-import only those contacts
This ensures unsubscribed preferences are preserved and your lists remain compliant.

If a Country column is included in your CSV:
Next to the Mobile Number column, click the yellow warning icon
