This was a question from one of our EIC Info Sessions. Our answer: Last year, the open calls on Submittable received 15-70 submissions. We work with each EIC to ensure their calls reach as widely as possible, and that each EIC feels they have received enough high-quality work to publish. The number of submissions also depends on the type of submission process. For example, if your call is open to all writers or if it is only open to a specific demographic of folks. For the anthology that received 15 last year, it was only open to a specific type of creator, whereas the one with 70 submissions was open to all writers/artists. And, of course, quantity does not always reflect quality.
