Help correct my grammar

I would like to apologize for the mistake that I have made. I was not aware that after doing the post. I should check whether it was grammatical or not. I overlooked this, and I hope in future I will be more alert regarding this matter.

I’am sorry about the twitter, I will improve from time to time by studying other libraries twitter. I’ll draft first and email to (Name) before tweet anything in future.

I would like to inform the grammatical error tweet already delete.
