As I further progress in my publisher contacts and press access, I received an email from PR Manager Michael Hoss of Deck 13, who gave me advice on some professional etiquette that’s common among press/industry communications. He told me when contacting the publisher, I should email them directly via the public email that I have posted on my channel/website. The reason for this is authenticity and association. It explained that there is no harm in using a personal email, however, in order to ensure a professional communication, my contact should be via my publishing source (my channel).
Seems simple, but from this, I am effectively contacting all other companies via my professional email to keep within a specific industry guideline.
