The first one is grammatical; the second isn't.

Hello Raymott. How are you?:-)

But both look similar to me. First one is a simple sentence and the next one is a complex sentence. I can not find the grammatical error( in my poor eye).
Thankss.

"I don't remember we received a letter" This part is ungrammatical.
