What should I know if I want to send a fan letter?
https://en.hololive.tv/contactHere it says the address I should send it to, but I'm worried about the part that says "We will only confirm items immediately if sent from electronic commerce sites". What does this mean? What counts as an electronic commerce site and what doesn't?
Also what information about myself should I write in the sender information part? Do I have to dox myself so my oshi can get the letter?
Another thing is that I have never sent a letter in my entire life, so what are the basics of sending a letter?
