February 2026: Sourcebooks has closed to submissions to all their imprints. They no longer have a submissions page, and it appears that the closure may be permanent.
We’ve reviewed Sourcebooks before here, and their Romance imprint here. Their Horror imprint is now a few years old and they have published a lot of books under that imprint now, although it’s hard to know exactly how many because they still do not have a formal Horror section on the site. Their book covers for this imprint are really well done. They have published many of Darcy Coates books, and they all appear to have sold well. The search function has been improved and searching the site for horror, can now bring up a lot of options that are actually in that genre.
They are actively seeking agented and unagented submissions of horror fiction between 80,000 and 100,000 words in length. They are looking for “strong writers of all ethnicities, races, sexualities, gender identities, abilities and ages, whose stories have something fresh to offer in the Horror genre.”
All submissions must be made via email with word attachments. Include a 1-3 page synopsis which discloses the ending, a short query letter in the email itself, and if you have a track record include your sales history. You should also attach the full manuscript. They try to respond to all submissions within 8-12 weeks.
