It allows users to create personalized emails from the data in an Excel sheet. They write a template like
Hello {Name}

The mailer automatically fills out the gaps with the corresponding column of the Excel sheet.
Since it's been running, I got a single one-time payment (about four years ago). I'm using it a lot myself though.
Luckily, it's almost free to run (on a 13$/m Hetzner machine, shared with about 10 other applications). And as a teacher, I used it to send over 4000 emails containing grades and similar stuff to my students.
If you could include a generated PDF using the same simple template concept which gets attached to an (also templated) e-mail and ensure the e-mail isn't flagged as spam, and doesn't cost 60 dollars per user or some other such nonsense, I promise you there is a market for this. Big market.
Automatically replacing text in PDFs is not easy sadly. The problem is that the text doesn't automatically reflow if a long text is inserted. What exact application do you have in mind? It might be possible to use a Word file as a template, and automatically generate a personalized PDF from that.
