"Early in the morning" is a more common expression than "Early morning". "Checked Italki" is more accurate than "Checked on Italki". "Receipted" is not a commonly used verb in this context. "Received" is a more appropriate verb here. "Many helps" should be changed to "a lot of help". "Some sentence" should be changed to "sentences". "Less brainstorming" could be better phrased as "less mental effort". The exclamation mark at the end is appropriate in this context as it shows enthusiasm. Overall, the corrected version is clearer, more concise, and grammatically correct. Good job!
