Each time I go to the post office to mail out submissions, I come home with an enhanced appreciation for those journals which accept submissions via email. With the cost of postage, mailing envelope, SASE, paper, and printer ink, sending out can get costly. Fortunately, a number of good journals now accept via email, some only that way. Here's a short list of journals that accept by email. All of these accept simultaneous submissions unless indicated otherwise.
Print Journals That Accept Email Submissions
Barn Owl Review—new journal
Kenyon Review—no simultaneous submissions
Many Mountains Moving ($2 fee)
Meridian ($2 fee)
The Normal School—new journal
Pebble Lake Review
no multiple subs (which in my book means don’t submit more than one packet at a time—if the editor means no simultaneous submissions, that needs to be changed)
Third Coast Review
There's a much lengthier list maintained online by Louie Crew. There are a few drawbacks to this list: 1) it does not indicate which are print and which are online journals 2) there is a huge variation in quality of the journals. So do be sure to check guidelines and past issues carefully.

Let me know if you have any print journals to add to my list.
