Over the summer I had 4 people write me a LOR. I wanted to tell them thank you once I had news received news from a school, but now I am going into the new year with limited responses from medical schools and 0 thank you cards delivered. I am currently in the process of applying to masters programs as a back up, which means that I will have to ask them to rewrite their previous letters. I feel like I waited an awkwardly long amount of time to say thank you, but I don't want to ask them for more help without saying it first. Does anybody have any advice as to how I should go about asking them to change the LOR they wrote for me without seeming like I was ungrateful for their previous letters? I don't want to come across as rude.
Also, would it just be better to send an email instead of a card?
