Spintax and personalization

I am newbie, but training hard :wink:

Maybe somenone of you folks can help me: I am trying to understand spintax-rules better for my needs.
Do anyone knows how to combine spintax with @first name? so, that the whole sentence looks personal?

e. g. {Dear|Hi|Hello} @first name {how are you|everything fine|…}

thanks for giving my a hint!
