From what I’ve gathered it seems as though they no longer send out rejection letters through email. I submitted a comic back in 2021 and it took them 3 weeks to send a rejection email. I recently submitted again and will wait another 3 weeks and if I have not heard anything back by then I will assume it was not accepted.
I’ve been trying to search info about their submissions and what they look for when deciding whether or not to accept a comic but there is very limited information out there
