PDF trick

[Alpha1404]

Hello,
I have a funny problem.
Until now, my production was free. I'm going to charge for some of my writing.
For purely legal reasons, I will not put a paywall on my site. My only option? PDFs to send.
I've started looking around, but do you know of a solution to do mass tagging on PDFs to incorporate the identity of the people to whom the PDFs will be sent?
To give you an idea of the volume, we're talking about a minimum of 400 PDFs, each of which needs to be marked.

incorporate the identity? Please be more specific

I didn't understand the question clearly. Are you talking about sharing PDF files with a list of people?

You can upload the files in a Google drive folder and add their emails as viewers.

Or... Could do something else.. *totally different*.. work on an entirely different project perhaps...just sayin..

NO WAY ! My customers will kill me if I do that.

As usual, it was after I posted my question that I found the solution.
I can do a custom mailing with Word. I can include in the footer or header something specific to each customer. I generate the watermark in Excel, link the two elements and it does the job.
As a joke, I was looking for a solution on Linux and I found the solution on an Ubuntu forum, which comes from Microsoft.
