Verify your first email list

Prepare a file in a supported format. Keep the email column and the identifiers needed to match results back to your records. Remove unnecessary personal data. Open the list-upload workflow, select the file, and check the detected email column. Review the preview and any credit estimate before starting. Once processing completes, inspect the result categories and explanations. Export the rows appropriate for your workflow. Apply consent and suppression controls before sending. Troubleshooting: If the email column is not detected, verify its header and delimiter. If the file is rejected, check the published format and size limits. If work is still processing, check the job status before starting a duplicate upload.
