I constantly receive emails from editors asking me to submit papers for their journals.
However, only a handful of them originate from a trustworthy source. The vast majority are just scams — journals with no reputation at all, willing to publish an(y) article for a fee.
My biggest problem with that is that I lost one or two real good opportunities to publish because I dismissed the email, thinking it was a scam.
Is there a list that I can use to easily check the reputation of a journal, in order to avoid this to happen?
