Before submitting to a journal, the scope has to match the content of your submission. This is clear, however, many editors these says use this cliche statement "Thank you for submitting your manuscript. I regret to inform you that your manuscript does not fit within the scope of the journal and we must therefore reject it."
For instance as part of the scope of the journal, it reads " Big data, machine learning, and artificial intelligence applications and case studies", on seeing this, we submitted a paper where machine learning tools have been used (single and ensemble algorithm).
To add to those above, the transfer desk of elsevier suggested the journal as one of those that match our subject matter.
