Assuming that along with her comments she included a request to see the revision, yes, it is ok to use email for future correspondence, as long as this means
A related question ... If an editor emails you, does that mean you have an "email relationship" now and it's fine to use email for future correspondence? For instance, I had an editor email revision comments to me; I did the revision and now need to check in to see where it stands (many months have passed). Is it OK to email for this, or should I mail a letter inquiring?
- asking her if she would like the revision via email or via post (don't assume)
- not emailing her more than twice in a four-month period (editors are in contact with so very many people; if every one of them emailed us just once a month, our heads (and computers) would explode.)
Likewise, another editor I met said that I could email a manuscript to her. She rejected it but said she'd look at other stuff. OK to email again?
Ok to ask her via email if she'd like the manuscript via email or post.
