I'm applying to a job where I, thanks to a referral, already have I contact within the company. However, I'm not at all sure who will be reading my cover letter - my contact is a team lead, but not a hiring manager.
Is it appropriate to include both the contact person and a "catch them all" phrase in the salutation?
Dear Mr. Smith, dear AwesomeCompany Recruiting Team,
Bonus: I have exchanged a couple of emails with said contact, on a first name basis (as seems customary in the US, at least in the IT sector). Nevertheless, I feel it is inappropriate to address someone by first name in a cover letter. Is that correct? Or should I stick to address this person by first name even in formal writing?
