About this product

Signal Desk helps small teams review contact CSVs before using them. Map columns from different file formats, then check for missing values, malformed email formats, possible duplicates, and old check dates. Review flagged rows and download a copy of the CSV. Files are processed in your browser. Signal Desk checks data quality; it doesn’t verify whether an email can receive mail or enrich contact records.
