Could someone advise me please what kind of word/phrase is "thank you" or a "thank you" if you prefer. For example in this sample letter what sort of phrase is "thank you"?
What price are your bacon bits by the kilogram bag please?
Thank you for your time in this matter.

Further, is it a signature, greeting or tagline?
NB: Wasn't sure how to tag this, any edits for this appreciated.
