Umbrella Factory Magazine
https://umbrellafactorymagazine.com/submit/
I can recommend Umbrella Factory Magazine for your submissions!
Here are some reasons why I recommend them:
They are on their 79th issue! Wow!
They curate a wonderful and accessible collection of work available free to share online.
They are super friendly and supportive. (Antony lives just one town over from me!)
They offer a place on Submittable to share past contributor success stories. As I said, super supportive.
They use Submittable AND submissions are free.
