on Publishing … and Other Forms of Insanity:
Much like other genres of speculative fiction, horror enjoys a loyal, and possibly fixated, fan base.
Horror isn’t all blood and gore. The subgenres include everything from the mildly unsettling (like Twilight Zone), to splatterpunk (which is exactly what you think it is).
Some of the genres accepted by horror magazines include: humorous horror, holiday horror, psychological horror, science fiction horror, slasher horror, supernatural horror, gothic horror, erotic horror, teen horror and, of course, anything with zombies, werewolves, vampires, or other malevolent creatures.
Many of the magazines on this list also accept dark fiction, dark fantasy, and other genre crossovers that include a sinister mood.
