Can anyone suggest few scopus indexed journals related to marketing domain which process the peer review process fastly and give accept/reject decision quickly as compared to other journals ?
MDPI's sustainability has an array of Marketing streams, and process submissions very quickly, but there is much debate about this publishers scientific rigor" - refer to Wikipedia for an overview - https://en.wikipedia.org/wiki/MDPI.
Personally, my experiences have been generally good with this journal!
Journals treat every submission individually. The speed of decision-making depends on the quality of the submission, following the instructions, and of course, if the submission fit into the scope and aim of the journal.
