Most editors are happy to answer questions regarding submissions. If a lit mag seems like a good fit for your work and it happens to be a collaboration, found poem, or other more nontraditional form, contact them via email or on other social media to ask if they are open to such forms. If you receive a response and can share it with me here, I’ll note it for others in the future.
Most of the 35 listings have accepted found work or other unusual formats of poetry and/or claim that they will. They are listed alphabetically; some are currently accepting submissions, some are temporarily closed. I’ve also included a link to their Duotrope page, which will allow you to track deadlines if you currently subscribe to Duotrope.
