When you say the first 5 chapters, you mean the first 5 Tapas chapters? Not the first 5 chapters of the book as it would be when printed?
If we have a successful novel elsewhere with a certain amount of readers/subscribers, or if we have a non-exclusive contract with another platform/publisher, would that help increase our chances of getting selected for premium or decrease them? Do we include that in the cover letter?
When considering a novel for premium, do you take into account its current success or lack of on Tapas? Because there are many, many hidden gems on Tapas that just get buried because they are never put in front of the readers.
If one gets rejected now, can they re-apply with the same novel again in the future? For example, if they get rejected then go to another site and achieve a lot of success there, can they come back and re-apply? And if they do would there be a good chance of getting accepted? My intention isn't to question your ability to judge good novels, all I can say is that J.K.Rowling got rejected by 12 publishers.
You say that you might not respond to every submission, but how will we know whether we have been rejected or whether our submission has yet to be processed? How long does it usually take for you to process the submission?
