The information in the email response about the rejection reasons is rather generic. It goes as follows:
Due to the number of submissions we receive, which is many more than we can publish, I regret that the Journal will not be able to use your manuscript.
This decision was based on the editors' evaluation of the merits of your manuscript compared with those of the many others we receive. This evaluation includes consideration of the paper's interest to our readers, the originality and design of the study and the quality of the manuscript.
