Happy Monday huttle!

I've already applied online to a job posting but if I were to also mail a resume with an accompanying cover letter addressed directly to the hiring manager of an open role, would that be a better chance to reach the hiring manager? (Considering there are a ton of applicant resumes piling up already)

I'm hoping to set myself apart from other applicants for a paid internship in a role that I am really interested in and a career path that I'm trying to transition into and learn a lot from.

I'm planning to send my material via UPS/fed ex priority Mail. Before I send it out, are there any reasons not to do so?

Would it be detrimental to my chances for the opening?
