Upload a CSV file containing emails to verify them in bulk

Upload Your CSV File

Drag & drop your file here or click to browse

Instructions:

  1. Upload a CSV file with one email per line or one column
  2. Choose verification options (more checks = more accurate but slower)
  3. Wait for processing to complete
  4. Download results with valid and invalid emails separated

Note: SMTP checking is slower but more accurate. For large lists (>10,000), use only syntax and DNS checks.
