The first publication that accepted me was Weeds & Wildflowers. Dennett is the editor and a real doll. It really depends on the type of poetry you want to write. Haiku Hub is just for haiku, but they don’t let you put poems behind the paywall. (Not a big deal since it would take you 50 years to make any money off a haiku on this platform.) search on the tag poetry and a bunch of publications will come up. Read a bunch to see where you might be a good match, then fire away! Good luck!
