Hello and welcome to Apple Support Communities, thewoodshopguy.
If I understand your post correctly, you're trying to view PDF documents sent via email. I'm happy to help.
Follow these steps:
You can open PDF documents, such as a PDF attached to an email, with iBooks:
- Open the email with the PDF attachment, and tap the attachment.
- Tap the Share icon
.
- Tap "Copy to iBooks" to open the attachment in iBooks.

When you use iBooks to open a PDF, iBooks automatically saves a copy of the PDF to your iBooks PDF shelf.
The next time you sync your iOS device with a computer, your PDF saves to either iBooks or iTunes.
- For OS X Mavericks or later, your PDF syncs to your iBooks Library.
- For OS X Mountain Lion and earlier or Windows users, these PDFs will sync to your iTunes Book Library.

Use iBooks with PDF documents on your iPhone, iPad, or iPod touch
Let us know if that resolves this issue for you.
Thanks for using the Apple Support Communities. Take care.
