I'm currently job searching and writing cover letters, the job postings don't contain any information about who I'm supposed to address in my cover letter.
I went to Linkedin, looked through the employee list, and found a few employees who provide there company e-mail addresses. Would it be okay to contact them, and ask them who I should address my cover letter to or is this unprofessional?
I found this page, but it's about contacting the person directly responsible for hiring, I'm looking for the person responsible for hiring.
