I can't answer if the receiver should feel as if the letter should be written from the heart or not... but I think some businesses are interested in sending nice handwritten letters. I see people in jewelry and fashion industries interested in sending these crafted handwritten letters to their clients as a thank you note, etc. It seems like they value their packaging. I am still learning why some of my clients are interested in this product myself ¯\_(ツ)_/¯ . My conclusion is that they want to stand out.

I agree with the final conclusion. Thanks for answering
