Is it correct to use "I myself" together [duplicate]

Question

Is it correct to say "I myself will call you back"

Answer 1

I'm sure that some people would say this but it is pseudo-formal these days and rather clumsy-sounding in my opinion.

I prefer: "I will call you back myself."

Or: "I will call you back personally."

Note that the following ngram shows that not everyone agrees with my opinion. However you can see that the usage is declining slowly.

Google ngram: I myself
