If an editor or agent wants to provide you with their contact info, they are free to do so. However, in this age of cutbacks in the publishing industry, time is at a premium. Though publishing professionals enjoy speaking with prospective authors, it’s difficult to juggle multiple deadlines, wade through the slush pile, and spend fifteen minutes or more each time a writer calls wanting to check on the status of her submission. So, though you can see the company or agency name on Pubmission, the identities of the individuals contacting you shall remain safely anonymous (unless they decide otherwise).
