I applied for a position about 10 days ago and I feel like my resume has improved significantly since then. I'm considering applying again, but I'm unsure if I should use a second email to do so. I've tried to find the hiring manager's contact information to send my updated resume directly, but I haven't had any luck. I'm feeling a bit stuck and looking for advice on whether I should go ahead and reapply or if that might hurt my chances.
