Response to comiXology Submit has been overwhelmingly positive and the volume of submissions has been very high. Unlike other services, comiXology Submit curates the content uploaded through our portal and then once selected comiXology staffers then need to author the content in Guided View. So notification and release are unfortunately far from instantaneous.
As we try to get through the review process, there are things that can slow us down. File quality is the biggest hurdle. Combing how Guided View takes readers through a page with the new crop HD devices, things like pixilation and artifacting are more apparent. Submissions with poor file quality slows down the approval process. Please be proactive, please review our PDF generation guidelines (https://submit.comixology.com/site/formatting) to make sure your PDF file is the best quality it can be. You can update your PDF file at any time prior to the submission being approved simply by "withdrawing" it.
The second biggest hurdle is copyrighted material. If you use song lyrics or other copyrighted material in your submission, we will automatically reject the material.
