I think we may be getting terms mixed up, but just to be sure I need to confirm: I did not email you. I have only communicated with you here in these forums. I foolishly left my lap-top logged in on my desk while I left the office, so if you did get an email from me, well, it wasn't me. Or do you mean this correspondence here in these public forums? I only wonder because if you got an email, then my computer may not be secure…
Okay, on to other topics:
I don't know anything about "fast pencil" so cannot advise about that.
The web site development can certainly take a lot of time. But what you have now looks great. Spend time on your writing.
As for the email notifications, you are doing things in an un-blog-like way. If you were doing posts, people /general public could "follow" or "subscribe" to your blog. But you are using pages and those are not options. And you want to target a particular audience, so I think you will have to do that by hand, or in person, or something like that: let them know via personal email that you have a book they would be interested in publishing.
My husband has published a couple of articles in a regional paper and that happened via personal contact with the editor? publisher? (I'm not sure of the fellow's exact position.) My sister-in-law also used personal contacts (and friends of friends) to get her first book of poetry published 25 years ago. She's published a number of poetry books, and co-authored various other books, worked for the poetry foundation and has a good reputation among poets to continue: but it was / is a lot of work.
I assume you know all of that though.
