Probably it's an e-mail specific for that rather than the author's *personal* e-mail, meant to be used like one would a social media account. I've seen a lot of authors (manga and webtoons alike) that have shared a e-mail address to receive fanmail. I'm not sure how common it is for them to respond to it but my guess is it'd be like seeing an eastern author reply to a tweet sometimes or smth?
Though all in all it's becoming less frequent lately
Writing directly to the author and sending them emails, is that a thing???? I've read plenty of books and novel myself but, apart from their socials, I've never seen authors share their emails too. Is this thing common in Korean webnovels?
