What Is a Cover Letter Email Subject Line?

A cover letter email subject line is the short phrase or sentence you write in the subject field when sending your job application via email. It summarizes your purpose and helps the recruiter identify your message quickly.

Key Elements of a Strong Subject Line

• Job title
• Your name
• Reference number (if applicable)
• Relevant keywords
