Improved CSV Importer

We've updated our CSV importer so you can include emails, phone numbers, and data tags in a single file, eliminating the need to split and reformat your data.

What’s new:

  • Real-time validation: Get instant feedback on formatting errors before upload.
  • Smart column mapping: Easily align your CSV headers with OneSignal fields.
  • Email suppression support: Add or manage your suppression list directly in the file.
  • Upload history: View the status of your past imports for up to 30 days.
  • Helpful templates: Start quickly with a pre-built CSV example.

To try it out, go to the Import page in your OneSignal dashboard. The importer will guide you through mapping, validation, and reviewing your results.
