Hi ITRulz,
With just PrintShop Mail alone, while you can split a pdf on every records and save multiple splits in a folder, it won't let you control the name, and will automatically name them "XXXXXXXX_job2.pdf", "XXXXXXXX_job3.pdf", and so on...
However, it would be possible if you had PlanetPress Workflow, which can also integrate our PrintShop Mail software. It would allow you to generate a pdf file, split it and control the names of the splits. Of course, a PlanetPress Workflow license is rather expensive, especially if that's the only thing you need it for, but that's an option to consider.
