That tells you very clearly that the message did not just get to Pharaoh, it also got to the people. God gave Egypt fair warning of what was going to occur, and whether you were an Egyptian or whether you were an Israelite, if you wanted to heed that warning, you saved your skin. Do you think that if an Egyptian heard the warning about the blood on the doorpost and the lintel and so forth and decided to put it on his own house, do you think that person would have died even though he was firstborn? Absolutely not! He would have been covered by the blood of the lamb because he believed. God's promises go out to everybody.
