Should I apply for that position directly or send my resume to the company email?

The working principle of the recruitment website is to send an email to the mailbox of the enterprise leader or the person who posts the position. The content of the email is your resume and the position you applied for.

The recruitment website directly contacts the business personnel in need, and the company mailbox is maintained by customer service, which is not responsible for recruitment, so it is not effective to send them an email.
