だから is different from から. から is a small word you add to a reason. だから starts a new sentence. It shows your strong opinion. ので is like から but sounds softer. It shows a reason that is a fact. それで just shows one thing happened after another. It does not show a strong reason.
Watch out: 'だから' is casual. It is like saying 'so' or 'that's why' to a friend. Do not use 'だから' with your boss or teacher. Use 'ですから' instead. This makes your speech polite.
Use this when you want to say, "I already told you!" or "That's what I mean!" It shows you are firm or a little annoyed.
