Thanks! Right now don't have automatic integrations for those yet but we do allow you to individually save emails and docs. Full integrations and sync for Drive and Email coming soon!

So at present one needs to export a Google doc as PDF first? But then it won't have a stable URL, seems to me. Is there a way to upload (e.g. drag and drop -or- using a local folder) a PDF directly?

No need to export the Google doc as a PDF. Zenfetch can save Google docs directly by clicking the zenfetch button once your on that page :)

Yep we do support PDF upload today
