Turn Blog Posts Into An Ebook? Turning Blog Posts Into An Email Campaign?

Hey everyone!
I came up with an idea to write a blog post that is basically "50 Ways To _____" (sorry, my niche is confidential).
When I first wrote the outline for this article, I thought I would write 100 words per item.

But as I started writing, I couldn't help myself. Each of these 50 items is averaging about 300 words per section...I am still in the middle of writing this article, and I'm on item #30ish... and I'm at 10,000 words already!

I"m pretty sure that's TOO long for an article.

So I came up with an idea a couple of ideas:

Idea #1)

Truncate this article and focus only on maybe the top 10 or the top 20, capping the article around 3000 to 5000 words... But then creating an Amazon eBook with the full-length "article" which I estimate will probably actually be about 15,000 words when all is said and done.

I was thinking to include a link to my blog in the eBook...

And I could charge a little something for the ebook too, like $1.99 or something like that? (Or should i give it away for free?)

Idea #2)

Take each of the 50 ideas and turn them into their own emails in an email campaign... That's 50 emails right there! Each email would of course have affiliate links and / or links back to my website.

Question Regarding Ebooks:

I have never published an ebook before:
Is it considered "redundant" to have an ebook that has the same content as my blog?

Just trying to see if I can repurpose this content, rather than having to write something unique... ?

Eg) If someone reads my ebook and then goes to my website, and sees identical content on it, is that necessarily a bad thing?

Question Regarding Email List Campaigns:

Would it make sense to take each of my 50 list items and create a separate email in my campaign for each?

a) Should each contain an excerpt from the article and then link back to the actual blog post..?

Or

b) Should each email contain the entire blog post in is entirety, and there should be a link back to the main page of the blog website?

Or

Should I link directly to my affiliate offer directly from my email, rather than linking back to the blog main page / blog post itself?

Your feedback is greatly appreciated!
