The American Poetry Journal is now accepting unsolicited submissions...if you don't know what that means, it means you don't need an agent...
The good news is that they take online submissions, which anyone who has ever thumbed through The Poets Market will tell you is not something you can take for granted, even in the 21st century computer age...
The bad news is that they will not take anything that is previously published, and that means posted on sites like this...and I can tell you that is the case for 99.99% of "print" poetry publications...
But, if you have some unpublished poems, and don't mind waiting a year to see if they get accepted, it is an easy matter of e-mailing them in...
Here is the link...and good luck...
