Will my submission be rejected if I accidentally submit the non-blind version to a conference with double blind review? I recently submitted a paper for a conference, I'm pretty confident about the topic and contents of the paper, but I just realized I sent the copy where the authors' names are in it, i.e. not the "blind" version that the conference requires. And I realized this a few days from the notification due date, which is today. I cannot change my submission from EasyChair.

Do you think this will get me rejected? And what should I do now? Should I e-mail the organizer and send them the blind copy?
You might get rejected without review. I would write the Program Chair now, explain your accidental submission of the wrong version of the manuscript, and ask for permission to resubmit the correct version.
