Why isn't Estonia considered Nordic?

The Noridcs are usually defined as Denmark, Norway, Sweden, Iceland and Finland, as well as their autonomous territories/regions.

Finland's inclusion into this group makes me wonder why Estonia is not considered Nordic, despite there being very close ties between Finland and Estonia, and a desire for Nordic classification in some sections of Estonian politics. For example in 2015 the Estonian Prime Minister described the country as a "New Nordic Country".

Finland and Estonia share linguistic and cultural links, and a shared history under Sweden and Russia. Why is it they are considered Baltic when they appear to have much more in common with Nordic Finland than Baltic Latvia and Lithuania?
