Poetry Publishers Willing to Receive Submissions Electronically. Poets Online has been on the list for a number of years.
He lists poetry editors who are willing to receive submissions electronically with some preferring manuscripts in the body of an email message and others as attachments. Most of his entries have brief submission tips and direct you to a website.
Louie wisely suggests that you study a copy of the magazine or site archive to determine whether your material would have a fit with the other material published.
His page has been online since 1996 and visits each website at least once a month, and write to editors at least twice a year to confirm publications are still viable. he is also no fan of entry or reading fees or requiring an author to buy a copy of the publication to see her or his work. On the other hand, he says that he hopes "that all poets will be poetry consumers and subscribe voluntarily to a wide variety of literary magazines. It is vain to expect others to read our poetry if we have no abiding interest in poetry by other living writers."
