Here is sci fi writer John Scalzi on the dinosaurish habit of not accepting email submissions. He's talking about the big three sci fi magazines.
In our office, it’s very inconvenient to pass around an electronic submission from one reader to another. Why? Because you’re trying to lift a CRT from one desk to another? Put the submissions you want others to see into an online collaboration space, like, oh, Google Docs, which is free and dead simple to use. Heck, several people can look at the same submission at the same time that way, which is actually easier than passing around a paper version.
Y'know, there are so many literary magazines accepting e-subs now, maybe what we need is an outreach.
"Immersion in the life of the world, a willingness to be inhabited by and to speak for others, including those beyond the realm of the human, these are the practices not just of the bodhisattva but of the writer." --Jane Hirshfield
