The normal form of applying for a Job through an Email is by attaching your resume or attaching Biodata along with the Email you send.
Write inside the Mail content : My Resume attached with this Email.

Type your Qualification also within that mail. But dont include detailed Biodata inside E-mail. Instead attach biodata in word format(.txt) or document format(.doc) or rich text format (.rtf).
Every Email service provider supports attachment of files. Scan your Resume with Anti- Virus to ensure that your file does not contain a virus attached with it before sending resume.

Upload your Resume to Email server and then send to the email address of the Job Providing company.
Thank You.
