I am interested in submitting a manuscript to a certain scientific journal, because it is well ranked. The problem is that I am not sure if my manuscript totally meets the topics and requirements (e.g. lenght, etc.) of the journal.
I would like to send a letter to the editor of the journal in order to find out whether or not they believe my paper can be interesting to the readers and may fit the scope and conditions of the journal.
I have been told that, in cases like this, this option is better than just submitting the manuscript and getting it rejected.
So, my question is: Could you recommend me a letter model to this purpose?
In addition, in this similar question: [ When is it appropriate to contact the editor before submission to avoid rejection without review? ] they talk about even sending the whole manuscript to the editor in this pre-submission step! Actually, I was thinking of not even including the abstract of my work (but just a description) in this letter to the editor. Should I really include it?
