You’re sending course certificates. One student finished a single course, another finished three, another finished six. Each cert needs to stand on its own. pdfMachine merge generates one PDF per row and packages them as separate attachments — one email per student, however many certificates they earned.
Each row, its own PDF.
pdfMachine merge runs your template once per row and produces a separate file each time. Each PDF is a complete, standalone document.
Grouped by recipient, attached separately.
Rows sharing an email address land in one email — with each row’s PDF as its own attachment. Three rows for one student? One email, three attached certificates.
Pick this when each PDF must stand alone.
Different from each row appends (tip on building a single multi-page PDF) and line items (tip on items inside one document). Use this when recipients need to forward, file, or verify each doc on its own.
One merge. Some recipients get one. Some get five. The data decides.
