You’re sending out monthly rental statements. Each row in your spreadsheet has one property’s data; some owners have one rental, some have five. pdfMachine merge groups all an owner’s properties into one PDF, and sends each owner a single email — no matter how many rows behind it.
Each row generates a page.
pdfMachine merge runs your template once per row, then stacks the results into a single multi-page PDF — one row in, one page out.
Grouped by recipient.
Consecutive rows sharing an email address become one PDF. One owner with five properties? Five pages, one PDF, one email.
Different from line items.
Use this when each row is a full page on its own (a property statement, an account summary, a site report). For line items within one document, see the 'one or more rows generates a PDF' method instead.
One owner. All their pages. One attachment.
