You’re mail-merging policy renewals. Auto customers should also get the Auto safety brochure. Home customers get the Home one. Different file per row, same merge.
pdfMachine merge reads a merge field on each row and attaches the file that matches.
Match files to merge field values.
Tell pdfMachine merge which field drives the attachment (say product) and which folder holds the files. Auto picks Auto.pdf; Home picks Home.pdf.
Personalised PDF plus matched file.
Each email carries the recipient’s own merged PDF and the file that matches their data. Same merge, both attachments.
New product? Drop a file in.
Launching a new product line? Add NewProduct.pdf to the folder. The next merge picks it up automatically for every row that matches.
One merge. The right file every time.
Requires a pdfMachine merge license.
