CSV import failed or contacts not imported
Common CSV import issues: 1) File must be UTF-8 encoded CSV with headers in the first row. 2) Maximum 10,000 rows per import — split larger files. 3) Required column: 'email' — rows without a valid email are skipped (unless they have a linkedinUrl, which creates a LinkedIn-only prospect). 4) Check column mapping — after upload, you map CSV columns to WarmySender fields (email, firstName, lastName, company, role, phone, linkedinUrl, website, country, city, industry). 5) Duplicates are automatically skipped — if an email already exists in your workspace, it won't be imported again. 6) Suppressed emails are skipped — check your blocklist in Settings. 7) Invalid emails (failing MX validation) are skipped. 8) For custom fields, prefix your CSV column headers with 'custom:' (e.g., 'custom:department'). Check the import job status for a breakdown of created, skipped, duplicate, and invalid counts.
