Audience
Import contacts
Bring a CSV or Excel file into Banger: column matching, status rules, languages, and consent.
In this guide 4 sections
Import a file with Audience › Import contacts. Contacts are matched by email: existing contacts are updated, new ones are added.
Limits
- CSV or XLSX, up to 5,000 rows and 100 columns. For a workbook, pick the sheet.
- Need a template? Use Download sample CSV.
Import a file
- Choose Import contacts and select your file.
- Check the column matching. Banger matches columns from your last import, by AI, or by column name, and says which. Choose Review columns to change a match or a field type, or Use these columns to accept.
- If the file has a language column, check Languages in this file. Use language codes or names (
pt-BR, “Portuguese”). A country is not a language. Banger flags values it can’t read. - Optionally choose Add to list.
- Confirm that every subscribed contact agreed to receive Broadcast email, then run the import.
- Follow progress in Audience › Imports.

Status rules
- A status column must say subscribed, unsubscribed, bounced, or complained. Rows with other values are skipped.
- If values conflict, the most restrictive status wins.
- An import never resubscribes someone who opted out.
