Dear Ms. Hoy,
When submitting fillers, how long should I wait without hearing before submitting to another market? Am I under any obligation to tell the first magazine that I am withdrawing the filler and submitting it to another publication?
The publisher should have a response time listed in their writer’s guidelines or market listing. If they don’t, give them about 60-90 days and then notify them that you’re withdrawing your submission.
Many publications DO allow simultaneous submissions. In those cases, go ahead and submit simultaneously to more than one publication.
