A CV is a document that contains basic information about you, your education, work experience and other skills.
Before sending your CV, it is good to let a few people read it, listen to their comments and, if necessary, revise it.
For international companies, a CV in a foreign language is often required, mostly in English. It is also important to have this CV checked and possibly corrected.
An e-mail is usually provided directly in the CV. It's important to know if your e-mail address is appropriate to contact your employer. If you have an address, eg email@example.com, I recommend that you create a "smarter" address.
