Content for PBN's from customers' inquiries ??

I'm a real newbie, so forgive me if this subject has come up before, or if it's an obvious 'No No !'.

I'm wanting to start setting up my own personal blog network and it has just suddenly occurred to me that I possibly have a huge amount of niche specific content sitting in my email inbox... about 9 years worth. Most of these are questions relating to my products, which I have answered. I probably get 1 or 2 emails a day relating to something about my products..

Would this stuff be useful to post on my blogs just to add some content or is there a problem which hasn't occurred to me yet ?

Great if I could get some advice here.

I would create a FAQ page out of those, or use them as a skeleton for a more in-depth content.

Your PBN is supposed to look like it's owned by random other people. Why post in depth info on your products (which only you can know) onto your PBN? It will obviously look like you're the author...

Hi Kennyg,

for sure, this mails are very helpful for a PGN! How long are the answers who you given? More then 200 / 300 words?
I see this similar like SEOHanK - go deeper in the content, further expand your answers and make for each topic a blog with 10 / 15 articles.

Best Regards
