Giveaways, posts asking for recommendations, and resharing work you admire from other pubs/writers are all pretty reliable ways to get engagement! If you want to do frequent posts, you could come up with weekly series like ICYMI reposts of new work, book/reading recs, or micro-interviews/features about writers you publish (or other experimental poets in the community). Collaboration with writers and new pubs could promising (anything that'd invite tags/reposts). Bluesky or a newsletter/mailing list might be worth a shot. Twitter's combustion has made getting the word out a little more challenging, but I've been trying to reframe the whole thing as a chance to think about marketing in a new way rather than an outright obstacle, lol. Wishing you luck!!
