2 Split settings
Choose how the PDF should be sliced into smaller documents.
For example, N = 1 for single-page letters, N = 2 for 2-page letters.
3 Naming & split
For mail-merged PDFs, “Use line AFTER selected line” is usually best for naming.
Mail-merge Field detection
“Use line AFTER selected line (mail merge)” works like this:
  • You load page 1’s text.
  • You click the line that appears before the field (e.g. the LETTER heading).
  • Each split then uses the line immediately after that as the filename.
