How to reply to the birthday party news?

How should I reply to the birthday party text message? I should be able to reply after receiving the birthday party text message: thank you.

Because the news of the birthday party is to invite you to the party, just say thank you. It means that you will attend on time after receiving the text message. On my friends' birthdays, I will only send them four words at the first time: "Happy birthday!" " "There are too many blessing messages now, and plagiarism is nothing new. It's better that these four words are from the heart, spelled one by one, and more real. When I receive the blessing, I will only say "thank you". I think it's hypocritical to copy a long paragraph of so-called true feelings and send it over. When I receive my blessing, I will only say thank you, and I mean it. There is no need to send anything too fancy.
