"Friday is the best day of the week" is an opinion
Answer:
The answer is ineffective since it doesn't describe what the field is or what the writer specifically did in that field.
To sound more sophisticated it could be written as: Hello, Cory
To add punctuation it would be simply: Hi, Cory
Or if casually like if you were texting it could be: Hi Core- left the same.
If you could please include a little more about the question, you could get a more reliable answer.
