Institutional versus commercial email addresses: which one to use in your publications?

Peer review scams - in which reviews were submitted under the names of real researchers but with fake, non-institutional emails administered by those involved - have heightened curiosity about the email addresses used by researchers in their publications. Ronald Rousseau reports on research examining the prevalence of commercial email addresses in scholarly articles, their distribution per country, and whether there is a difference in visibility between articles with institutional and commercial emails, as measured by citations. Use of commercial emails is on the rise, particularly among researchers from Brazil, Russia, India, and China, but those articles with institutional emails were shown to receive more than double the number of citations.
