Email not a good idea
Email to Goodnote 5 is not a good feature.
I have Goodnote 5 installed on my iPad and home computer Mac. The PDF files are no issue to sync. When I am in the compony which only use the Window 10 computer, I can't easily put the PDF file into the Goodnote easily. The easier method I know is to put the files into the Dropbox or cloud storage. Then, import the PDF files to the Goodnote 5 from Mac or iPad when I go back home. If I annotate the files using other software then follow the same steps to import into the Goodnote5, I might lost trace which is the latest files.
The best solution is to use airSlate PDFfiller to annotate in company and sync using Dropbox. When I reach home, I can use Goodnote5 to annotate from iPad or Mac.
