The best way to promote a blog's article is through Emails. Don't you guys agree?

Yeah, you can say if you have an organically grown email list then its the most cost effective way.

Through email will not be effective due to selected people and the worst it only goes to spam folder if finds out that they even didn't know the sender. There are many mediums to use like related blog sites, related forums, social media, etc.

It is effective if you have already built a good email list. Otherwise it will be just a waste of money and effort. Try finding other methods of promotion through social channels and forums etc.
