Writing the Email in Spanish and English: Brief Recommendations.
Dr. María Nayra Rodríguez Rodríguez, a member of the IATEXT, and Dr. Soraya García-Sánchez have recently published an electronic style recommendation guide in Spanish "Writing E-mail in Spanish and English: Brief Recommendations."
This document has suggestions for the correct use of Spanish and English in institutional emails, that is, it is intended to provide basic guidance on this topic. The guide is divided into two chapters, the first with style tips for preparing e-mails in Spanish and the second, with insights for e-mails in English for an institutional recipient.
