1, the email name should be regular. When reading an email, the recruiter will first see who sent it. If you use too many "nicknames" and "common names", you will often leave a bad first impression. The mailbox should also use a formal and serious mailbox.
2. The main information of recruitment should be briefly explained in the email title. The correct spelling should be "apply for the position of ×××-majoring in ×× University". You only write one resume, and no one will spend a lot of time picking out work, school and major from your resume in front of many resumes.
